9 characteristics of critical thinking (and how you can develop them)

It's no secret that critical thinking is essential for growth and success. Yet many people aren't quite sure what it means — it sounds like being a critic or cynical, traits that many people want to avoid.

However, thinking critically isn't about being negative. On the contrary, effective critical thinkers possess many positive traits. Attributes like curiosity, compassion, and communication are among the top commonalities that critical thinkers share, and the good news is that we can all learn to develop these capabilities.

This article will discuss some of the principal characteristics of critical thinking and how developing these qualities can help you improve your decision-making and problem-solving skills. With a bit of self-reflection and practice, you'll be well on your way to making better decisions, solving complex problems, and achieving success across all areas of your life.

What is critical thinking?

Scholarly works on critical thinking propose many ways of interpreting the concept ( at least 17 in one reference! ), making it challenging to pinpoint one exact definition. In general, critical thinking refers to rational, goal-directed thought through logical arguments and reasoning. We use critical thinking to objectively assess and evaluate information to form reasonable judgments.

Critical thinking has its roots in ancient Greece. The philosopher Socrates is credited with being one of the first to encourage his students to think critically about their beliefs and ideas. Socrates believed that by encouraging people to question their assumptions, they would be able to see the flaws in their reasoning and improve their thought processes.

Today, critical thinking skills are considered vital for success in academia and everyday life. One of the defining " 21st-century skills ," critical thinking is integral to problem-solving, decision making, and goal setting.

Why is it necessary to develop critical thinking skills?

Critical thinking skills help us learn new information, understand complex concepts, and make better decisions. The ability to be objective and reasonable is an asset that can enhance personal and professional relationships.

The U.S. Department of Labor reports critical thinking is among the top desired skills in the workplace. The ability to develop a properly thought-out solution in a reasonable amount of time is highly valued by employers. Companies want employees who can solve problems independently and work well in a team. A desirable employee can evaluate situations critically and creatively, collaborate with others, and make sound judgments.

Critical thinking is an essential component of academic study as well. Critical thinking skills are vital to learners because they allow students to build on their prior knowledge and construct new understandings. This will enable learners to expand their knowledge and experience across various subjects.

Despite its importance, though, critical thinking is not something that we develop naturally or casually. Even though critical thinking is considered an essential learning outcome in many universities, only 45% of college students in a well-known study reported that their skills had improved after two years of classes.

9 characteristics of critical thinking

Clearly, improving our ability to think critically will require some self-improvement work. As lifelong learners, we can use this opportunity for self-reflection to identify where we can improve our thinking processes.

Strong critical thinkers possess a common set of personality traits, habits, and dispositions. Being aware of these attributes and putting them into action can help us develop a strong foundation for critical thinking. These essential characteristics of critical thinking can be used as a toolkit for applying specific thinking processes to any given situation.

Curiosity is one of the most significant characteristics of critical thinking. Research has shown that a state of curiosity drives us to continually seek new information . This inquisitiveness supports critical thinking as we need to constantly expand our knowledge to make well-informed decisions.

Curiosity also facilitates critical thinking because it encourages us to question our thoughts and mental models, the filters we use to understand the world. This is essential to avoid critical thinking barriers like biases and misconceptions. Challenging our beliefs and getting curious about all sides of an issue will help us have an open mind during the critical thinking process.

Actionable Tip: Choose to be curious. When you ask “why,” you learn about things around you and clarify ambiguities. Google anything you are curious about, read new books, and play with a child. Kids have a natural curiosity that can be inspiring.

2. Analytical

Investigation is a crucial component of critical thinking, so it's important to be analytical. Analytical thinking involves breaking down complex ideas into their simplest forms . The first step when tackling a problem or making a decision is to analyze information and consider it in smaller pieces. Then, we use critical thinking by gathering additional information before getting to a judgment or solution.

Being analytical is helpful for critical thinking because it allows us to look at data in detail. When examining an issue from various perspectives, we should pay close attention to these details to arrive at a decision based on facts. Taking these steps is crucial to making good decisions.

Actionable Tip: Become aware of your daily surroundings. Examine how things work — breaking things down into steps will encourage analysis. You can also play brain and puzzle games. These provide an enjoyable way to stimulate analytical thinking.

3. Introspective

Critical thinkers are typically introspective. Introspection is a process of examining our own thoughts and feelings. We do this as a form of metacognition, or thinking about thinking. Researchers believe that we can improve our problem-solving skills by using metacognition to analyze our reasoning processes .

Being introspective is essential to critical thinking because it helps us be self-aware. Self-awareness encourages us to acknowledge and face our own biases, prejudices, and selfish tendencies. If we know our assumptions, we can question them and suspend judgment until we have all the facts.

Actionable Tip: Start a journal. Keep track of your thoughts, feelings, and opinions throughout the day, especially when faced with difficult decisions. Look for patterns. You can avoid common thought fallacies by being aware of them.

4. Able to make inferences

Another characteristic of critical thinking is the ability to make inferences, which are logical conclusions based on reviewing the facts, events, and ideas available. Analyzing the available information and observing patterns and trends will help you find relationships and make informed decisions based on what is likely to happen.

The ability to distinguish assumptions from inferences is crucial to critical thinking. We decide something is true by inference because another thing is also true, but we decide something by assumption because of what we believe or think we know. While both assumptions and inferences can be valid or invalid, inferences are more rational because data support them.

Actionable Tip: Keep an eye on your choices and patterns during the day, noticing when you infer. Practice applying the Inference Equation — I observe + I already know = So now I am thinking — to help distinguish when you infer or assume.

5. Observant

Observation skills are also a key part of critical thinking. Observation is more than just looking — it involves arranging, combining, and classifying information through all five senses to build understanding. People with keen observation skills notice small details and catch slight changes in their surroundings.

Observation is one of the first skills we learn as children , and it is critical for problem-solving. Being observant allows us to collect more information about a situation and use that information to make better decisions and solve problems. Further, it facilitates seeing things from different perspectives and finding alternative solutions.

Actionable Tip: Limit your use of devices, and be mindful of your surroundings. Notice and name one thing for each of your five senses when you enter a new environment or even a familiar one. Being aware of what you see, hear, smell, taste, and touch allows you to fully experience the moment and it develops your ability to observe your surroundings.

6. Open-minded and compassionate

Open-minded and compassionate people are good critical thinkers. Being open-minded means considering new ideas and perspectives, even if they conflict with your own. This allows you to examine different sides of an issue without immediately dismissing them. Likewise, compassionate people can empathize with others, even if they disagree. When you understand another person's point of view, you can find common ground and understanding.

Critical thinking requires an open mind when analyzing opposing arguments and compassion when listening to the perspective of others. By exploring different viewpoints and seeking to understand others' perspectives, critical thinkers can gain a more well-rounded understanding of an issue. Using this deeper understanding, we can make better decisions and solve more complex problems.

Actionable Tip: Cultivate open-mindedness and compassion by regularly exposing yourself to new ideas and views. Read books on unfamiliar topics, listen to podcasts with diverse opinions, or talk with people from different backgrounds.

7. Able to determine relevance

The ability to assess relevance is an essential characteristic of critical thinking. Relevance is defined as being logically connected and significant to the subject. When a fact or statement is essential to a topic, it can be deemed relevant.

Relevance plays a vital role in many stages of the critical thinking process . It's especially crucial to identify the most pertinent facts before evaluating an argument. Despite being accurate and seemingly meaningful, a point may not matter much to your subject. Your criteria and standards are equally relevant, as you can't make a sound decision with irrelevant guidelines.

Actionable Tip: When you're in a conversation, pay attention to how each statement relates to what you're talking about. It's surprising how often we stray from the point with irrelevant information. Asking yourself, "How does that relate to the topic?" can help you spot unrelated issues.

Critical thinking requires willingness. Some scholars argue that the "willingness to inquire" is the most fundamental characteristic of critical thinking , which encompasses all the others. Being willing goes hand in hand with other traits, like being flexible and humble. Flexible thinkers are willing to adapt their thinking to new evidence or arguments. Those who are humble are willing to acknowledge their faults and recognize their limitations.

It's essential for critical thinking that we have an open mind and are willing to challenge the status quo. The willingness to question assumptions, consider multiple perspectives, and think outside the box allows critical thinkers to reach new and necessary conclusions.

Actionable Tip: Cultivate willingness by adopting a growth mindset. See challenges as learning opportunities. Celebrate others' accomplishments, and get curious about what led to their success.

9. Effective communicators

Being a good critical thinker requires effective communication. Effective critical thinkers know that communication is imperative when solving problems. They can articulate their goals and concerns clearly while recognizing others' perspectives. Critical thinking requires people to be able to listen to each other's opinions and share their experiences respectfully to find the best solutions.

A good communicator is also an attentive and active listener. Listening actively goes beyond simply hearing what someone says. Being engaged in the discussion involves:

• Listening to what they say
• Being present
• Asking questions that clarify their position

Actively listening is crucial for critical thinking because it helps us understand other people's perspectives.

Actionable Tip: The next time you speak with a friend, family member, or even a complete stranger, take the time to genuinely listen to what they're saying. It may surprise you how much you can learn about others — and about yourself — when you take the time to listen carefully.

The nine traits above represent just a few of the most common characteristics of critical thinking. By developing or strengthening these characteristics, you can enhance your capacity for critical thinking.

Get to the core of critical thinking

Critical thinking is essential for success in every aspect of life, from personal relationships to professional careers. By developing your critical thinking skills , you can challenge the status quo and gain a new perspective on the world around you. You can start improving your critical thinking skills today by determining which characteristics of critical thinking you need to work on and using the actionable tips to strengthen them. With practice, you can become a great critical thinker.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Table of contents

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Ideas to Action (i2a)

• Paul-Elder Critical Thinking Framework

Critical thinking is that mode of thinking – about any subject, content, or problem — in which the thinker improves the quality of his or her thinking by skillfully taking charge of the structures inherent in thinking and imposing intellectual standards upon them. (Paul and Elder, 2001). The Paul-Elder framework has three components:

• The elements of thought (reasoning)
• The  intellectual standards that should be applied to the elements of reasoning
• The intellectual traits associated with a cultivated critical thinker that result from the consistent and disciplined application of the intellectual standards to the elements of thought

According to Paul and Elder (1997), there are two essential dimensions of thinking that students need to master in order to learn how to upgrade their thinking. They need to be able to identify the "parts" of their thinking, and they need to be able to assess their use of these parts of thinking.

Elements of Thought (reasoning)

The "parts" or elements of thinking are as follows:

• All reasoning has a purpose
• All reasoning is an attempt to figure something out, to settle some question, to solve some problem
• All reasoning is based on assumptions
• All reasoning is done from some point of view
• All reasoning is based on data, information and evidence
• All reasoning is expressed through, and shaped by, concepts and ideas
• All reasoning contains inferences or interpretations by which we draw conclusions and give meaning to data
• All reasoning leads somewhere or has implications and consequences

Universal Intellectual Standards

The intellectual standards that are to these elements are used to determine the quality of reasoning. Good critical thinking requires having a command of these standards. According to Paul and Elder (1997 ,2006), the ultimate goal is for the standards of reasoning to become infused in all thinking so as to become the guide to better and better reasoning. The intellectual standards include:

Intellectual Traits

Consistent application of the standards of thinking to the elements of thinking result in the development of intellectual traits of:

• Intellectual Humility
• Intellectual Courage
• Intellectual Empathy
• Intellectual Autonomy
• Intellectual Integrity
• Intellectual Perseverance
• Confidence in Reason
• Fair-mindedness

Characteristics of a Well-Cultivated Critical Thinker

Habitual utilization of the intellectual traits produce a well-cultivated critical thinker who is able to:

• Raise vital questions and problems, formulating them clearly and precisely
• Gather and assess relevant information, using abstract ideas to interpret it effectively
• Come to well-reasoned conclusions and solutions, testing them against relevant criteria and standards;
• Think open-mindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and practical consequences; and
• Communicate effectively with others in figuring out solutions to complex problems

Critical Thinking

Developing the right mindset and skills.

By the Mind Tools Content Team

We make hundreds of decisions every day and, whether we realize it or not, we're all critical thinkers.

We use critical thinking each time we weigh up our options, prioritize our responsibilities, or think about the likely effects of our actions. It's a crucial skill that helps us to cut out misinformation and make wise decisions. The trouble is, we're not always very good at it!

In this article, we'll explore the key skills that you need to develop your critical thinking skills, and how to adopt a critical thinking mindset, so that you can make well-informed decisions.

What Is Critical Thinking?

Critical thinking is the discipline of rigorously and skillfully using information, experience, observation, and reasoning to guide your decisions, actions, and beliefs. You'll need to actively question every step of your thinking process to do it well.

Collecting, analyzing and evaluating information is an important skill in life, and a highly valued asset in the workplace. People who score highly in critical thinking assessments are also rated by their managers as having good problem-solving skills, creativity, strong decision-making skills, and good overall performance.

Critical thinkers possess a set of key characteristics which help them to question information and their own thinking. Focus on the following areas to develop your critical thinking skills:

Being willing and able to explore alternative approaches and experimental ideas is crucial. Can you think through "what if" scenarios, create plausible options, and test out your theories? If not, you'll tend to write off ideas and options too soon, so you may miss the best answer to your situation.

To nurture your curiosity, stay up to date with facts and trends. You'll overlook important information if you allow yourself to become "blinkered," so always be open to new information.

But don't stop there! Look for opposing views or evidence to challenge your information, and seek clarification when things are unclear. This will help you to reassess your beliefs and make a well-informed decision later. Read our article, Opening Closed Minds , for more ways to stay receptive.

Logical Thinking

You must be skilled at reasoning and extending logic to come up with plausible options or outcomes.

It's also important to emphasize logic over emotion. Emotion can be motivating but it can also lead you to take hasty and unwise action, so control your emotions and be cautious in your judgments. Know when a conclusion is "fact" and when it is not. "Could-be-true" conclusions are based on assumptions and must be tested further. Read our article, Logical Fallacies , for help with this.

Use creative problem solving to balance cold logic. By thinking outside of the box you can identify new possible outcomes by using pieces of information that you already have.

Self-Awareness

Many of the decisions we make in life are subtly informed by our values and beliefs. These influences are called cognitive biases and it can be difficult to identify them in ourselves because they're often subconscious.

Practicing self-awareness will allow you to reflect on the beliefs you have and the choices you make. You'll then be better equipped to challenge your own thinking and make improved, unbiased decisions.

One particularly useful tool for critical thinking is the Ladder of Inference . It allows you to test and validate your thinking process, rather than jumping to poorly supported conclusions.

Developing a Critical Thinking Mindset

Combine the above skills with the right mindset so that you can make better decisions and adopt more effective courses of action. You can develop your critical thinking mindset by following this process:

Gather Information

First, collect data, opinions and facts on the issue that you need to solve. Draw on what you already know, and turn to new sources of information to help inform your understanding. Consider what gaps there are in your knowledge and seek to fill them. And look for information that challenges your assumptions and beliefs.

Be sure to verify the authority and authenticity of your sources. Not everything you read is true! Use this checklist to ensure that your information is valid:

• Are your information sources trustworthy ? (For example, well-respected authors, trusted colleagues or peers, recognized industry publications, websites, blogs, etc.)
• Is the information you have gathered up to date ?
• Has the information received any direct criticism ?
• Does the information have any errors or inaccuracies ?
• Is there any evidence to support or corroborate the information you have gathered?
• Is the information you have gathered subjective or biased in any way? (For example, is it based on opinion, rather than fact? Is any of the information you have gathered designed to promote a particular service or organization?)

If any information appears to be irrelevant or invalid, don't include it in your decision making. But don't omit information just because you disagree with it, or your final decision will be flawed and bias.

Now observe the information you have gathered, and interpret it. What are the key findings and main takeaways? What does the evidence point to? Start to build one or two possible arguments based on what you have found.

You'll need to look for the details within the mass of information, so use your powers of observation to identify any patterns or similarities. You can then analyze and extend these trends to make sensible predictions about the future.

To help you to sift through the multiple ideas and theories, it can be useful to group and order items according to their characteristics. From here, you can compare and contrast the different items. And once you've determined how similar or different things are from one another, Paired Comparison Analysis can help you to analyze them.

The final step involves challenging the information and rationalizing its arguments.

Apply the laws of reason (induction, deduction, analogy) to judge an argument and determine its merits. To do this, it's essential that you can determine the significance and validity of an argument to put it in the correct perspective. Take a look at our article, Rational Thinking , for more information about how to do this.

Once you have considered all of the arguments and options rationally, you can finally make an informed decision.

Afterward, take time to reflect on what you have learned and what you found challenging. Step back from the detail of your decision or problem, and look at the bigger picture. Record what you've learned from your observations and experience.

Critical thinking involves rigorously and skilfully using information, experience, observation, and reasoning to guide your decisions, actions and beliefs. It's a useful skill in the workplace and in life.

You'll need to be curious and creative to explore alternative possibilities, but rational to apply logic, and self-aware to identify when your beliefs could affect your decisions or actions.

You can demonstrate a high level of critical thinking by validating your information, analyzing its meaning, and finally evaluating the argument.

What is critical thinking?

Jean Kaluza

Critical thinking involves analyzing all data before making a judgment, and it considers known and subconscious biases. It requires credible sources, evaluating the argument, assessing any alternate views, and testing the hypothesis.

Let’s look at everything you need to know about critical thinking. 

• Why is critical thinking important?

Critical thinking hinges on being rational and objective, which is useful in various disciplines and settings. It’s the keystone of science, humanities, and anyone wanting to have information literacy and engage independently without media and popular bias.

• 5 characteristics of critical thinking

Critical thinking has five main characteristics that affect any decision-making process:

Dispositions

Critical thinkers have certain traits and dispositions, so they can think through all parts of a problem. Some of these traits include:

Open-mindedness

Respecting evidence and data

Valuing fair-mindedness

Using clarity

Cognitive flexibility

The ability to make sound arguments is part of critical thinking, and they involve supporting evidence. You’ll consider several arguments for and against before coming to your reasoning.

You need to meet some conditions for something to be factual. Critical thinking means you can discern fact from fiction.

Metacognition

When you think about your thoughts, analyze them, and see other avenues of thinking, that is metacognition. Being able to do this means you can reach better hypotheses and more definite conclusions.

• 6 key critical thinking skills

Six thinking skills help a critical thinker create a thorough conclusion:

Identifying bias

Identifying your bias is a major factor in critical thinking. This internal bias can alter how you see evidence and read project data. It’s good to uncover bias when working with people, as it can create workplace inequalities and group discord.

Inference is the ability to come up with a logical conclusion from the available data and information. 

You must research the facts and information to generate your conclusion. Some projects or situations require much more research than others. 

Identification

The ability to identify problems and what is affecting that problem is called identification. The skill helps you know when to analyze a situation after seeing broken patterns or other issues.

Intellectual curiosity means you can question what’s happening around you and explore different measures of changing or affecting it. Beginning with an open mind full of wonder can help you see things others may not. It can also help you ‘ think outside the box.’

Judging relevance

A wealth of research can be part of a data set, but not all information is relevant. A key part of critical thinking is seeing what is and isn’t important. 

Relevance helps you stay focused and not wander to parts of a project or data set that aren't essential to your conclusion. 

• An example of critical thinking skills

Let’s imagine you’re reading about a new drug: One article shows thrilling results. 

Thinking critically, you compare the study cited in the article with other results. You discover that it’s an outlier—most other research has shown it’s ineffective in treating the condition. 

You take another look at the first journal article and see the drug company paid for it. With the outlier results, bias, and conflict of interest, you reject the study’s conclusion. 

• 9 actionable tips to improve critical thinking skills

Want to improve your critical thinking ability? Here are a few ways to boost that process: 

Play logic games

Spend time playing logic puzzles or other games that make you think critically.

Question your assumptions

When you notice you've made an assumption, question it and think about where that belief stems from.

Ask more questions

Increase the number of questions that you ask on a day-to-day basis. Preferably, use open questions instead of closed yes/no questions.

Practice active listening

Most people don’t truly listen to what others say. Developing active listening skills means you’ll pick up on a lot more in conversation. 

Go beyond the echo chamber

Diversify your thoughts and think outside your comfort zone. That may mean consuming media from a different source or having a discussion with someone with opposing views. 

Consider your actions

Before acting, think about the consequences of your actions and develop more than one way to respond. After considering your options, form a more logical and less emotional response.

This also applies when you have a problem. Try to think of multiple solutions and analyze how you came up with them.

Look for a mentor

Embrace individualism.

Forge your own thinking path: Don’t just follow the crowd. One way of fending off herd mentality is being aware of your thoughts and questioning what others are following.

Stay on top of problems

Develop the skills to identify problems in your home and work environment faster. Be more mindful of what is going on around you.

How do you identify a critical thinker?

People who can stay objective during a situation and follow the facts are critical thinkers. Separating emotion when making a decision or judgment is another core aspect.

Identifying these skills in advance is a great way to be a more competent manager and create a better work environment.

What are the types of thinkers?

There are five types of thinkers: Realists, analysts, synthesists, idealists, and pragmatists.

Realists go headstrong into problems without issue.

Analysts need procedure to look at all the data first. 

Synthesists consider possibilities creatively for their problems. 

Idealists set a high bar and work toward goals for the issue. 

Pragmatists want fast and long-term results while working through the problem logically.

What part of the brain is responsible for critical thinking?

The prefrontal cortex (PFC) is responsible for behavior, thinking, and emotional response. As the most evolved part of the brain, it’s the primary region for critical thinking.

What are the 4 Cs of 21st-century skills?

The four Cs are communication, critical thinking, creativity, and collaboration.

Communication ensures you consider everyone's thoughts and draw other conclusions. 

Critical thinking means you can logically create an unbiased response. 

Creativity finds new ways to respond to information. 

Collaboration helps mindsets work together to create a unified front for the conclusion.

Critical thinking has been defined in numerous ways. At its most basic, we can think of critical thinking as active thinking in which we evaluate and analyze information in order to determine the best course of action. We will look at more expansive definitions of critical thinking and its components in the following pages. Before we get there, though, let's consider a hypothetical example of critical thinking in action.

We are approaching a new age of synthesis. Knowledge cannot be merely a degree or a skill... it demands a broader vision, capabilities in critical thinking and logical deduction, without which we cannot have constructive progress. ~ Li Ka Shing

Shonda was researching information for her upcoming persuasive speech. Her goal with the speech was to persuade her classmates to drink a glass of red wine every day. Her argument revolved around the health benefits one can derive from the antioxidants found in red wine. Shonda found an article reporting the results of a study conducted by a Dr. Gray. According to Dr. Gray’s study, drinking four or more glasses of wine a day will help reduce the chances of heart attack, increase levels of good cholesterol, and help in reducing unwanted fat. Without conducting further research, Shonda changed her speech to persuade her classmates to drink four or more glasses of red wine per day. She used Dr. Gray’s study as her primary support. Shonda presented her speech in class to waves of applause and support from her classmates. She was shocked when, a few weeks later, she received a grade of “D”. Shonda’s teacher had also found Dr. Gray’s study and learned it was sponsored by a multi- national distributor of wine. In fact, the study in question was published in a trade journal targeted to wine and alcohol retailers. If Shonda had taken a few extra minutes to critically examine the study, she may have been able to avoid the dreaded “D.”

Shonda’s story is just one of many ways that critical thinking impacts our lives. Throughout this chapter we will consider the importance of critical thinking in all areas of communication, especially public speaking. We will first take a more in-depth look at what critical thinking is – and isn’t.

Before we get too far into the specifics of what critical thinking is and how we can do it, it’s important to clear up a common misconception. Even though the phrase critical thinking uses the word “critical,” it is not a negative thing. Being critical is not the same thing as criticizing. When we criticize something, we point out the flaws and errors in it, exercising a negative value judgment on it. Our goal with criticizing is less about understanding than about negatively evaluating. It’s important to remember that critical thinking is not just criticizing. While the process may involve examining flaws and errors, it is much more.

critical thinking defined

Just what is critical thinking then? To help us understand, let’s consider a common definition of critical thinking. The philosopher John Dewey, often considered the father of modern day critical thinking, defines critical thinking as:

“Active, persistent, careful consideration of a belief or supposed form of knowledge in light of the grounds that support it and the further conclusions to which it tends” (Dewey, 1933, p. 9).

The first key component of Dewey’s definition is that critical thinking is active . Critical thinking must be done by choice. As we continue to delve deeper into the various facets of critical thinking, we will learn how to engage as critical thinkers.

Probably one of the most concise and easiest to understand definitions is that offered by Barry Beyer: "Critical thinking... means making reasoned judgments" (Beyer, 1995, p. 8). In other words, we don’t just jump to a conclusion or a judgment. We rationalize and justify our conclusions. A second primary component of critical thinking, then, involves questioning. As critical thinkers, we need to question everything that confronts us. Equally important, we need to question ourselves and ask how our own biases or assumptions influence how we judge something.

In the following sections we will explore how to do critical thinking more in depth. As you read through this material, reflect back on Dewey’s and Beyer’s definitions of critical thinking.

critical thinking traits and skills

Critical thinkers tend to exhibit certain traits that are common to them. These traits are summarized in Table 6.1 (adapted from Facione, 1990, p. 6):

Recall that critical thinking is an active mode of thinking. Instead of just receiving messages and accepting them as is, we consider what they are saying. We ask if messages are well-supported. We determine if their logic is sound or slightly flawed. In other words, we act on the messages before we take action based on them. When we enact critical thinking on a message, we engage a variety of skills including: listening, analysis, evaluation, inference and interpretation or explanation, and self- regulation (adapted from Facione, 1990, p. 6)

Next, we will examine each of these skills and their role in critical thinking in greater detail. As you read through the explanation of and examples for each skill, think about how it works in conjunction with the others. It’s important to note that while our discussion of the skills is presented in a linear manner, in practice our use of each skill is not so straightforward. We may exercise different skills simultaneously or jump forward and backward.

Without an open-minded mind, you can never be a great success. ~ Martha Stewart

In order to understand listening, we must first understand the difference between listening and hearing . At its most basic, hearing refers to the physiological process of receiving sounds, while listening refers to the psychological process of interpreting or making sense of those sounds.

Every minute of every day we are surrounded by hundreds of different noises and sounds. If we were to try to make sense of each different sound we would probably spend our day just doing this. While we may hear all of the noises, we filter out many of them. They pass through our lives without further notice. Certain noises, however, jump to the forefront of our consciousness. As we listen to them, we make sense of these sounds. We do this every day without necessarily thinking about the process. Like many other bodily functions, it happens without our willing it to happen.

Critical thinking requires that we consciously listen to messages. We must focus on what is being said – and not said. We must strive not to be distracted by other outside noises or the internal noise of our own preconceived ideas. For the moment we only need to take in the message.

Listening becomes especially difficult when the message contains highly charged information. Think about what happens when you try to discuss a controversial issue such as abortion. As the other person speaks, you may have every good intention of listening to the entire argument.

However, when the person says something you feel strongly about you start formulating a counter-argument in your head. The end result is that both sides end up talking past each other without ever really listening to what the other says.

Once we have listened to a message, we can begin to analyze it. In practice we often begin analyzing messages while still listening to them. When we analyze something, we consider it in greater detail, separating out the main components of the message. In a sense, we are acting like a surgeon on the message, carving out all of the different elements and laying them out for further consideration and possible action.

Let’s return to Shonda’s persuasive speech to see analysis in action. As part of the needs section of her speech, Shonda makes the following remarks:

If we were to analyze this part of Shonda’s speech (see Table \(\PageIndex{2}\)), we could begin by looking at the claims she makes. We could then look at the evidence she presents in support of these claims. Having parsed out the various elements, we are then ready to evaluate them and by extension the message as a whole.

When we evaluate something we continue the process of analysis by assessing the various claims and arguments for validity. One way we evaluate a message is to ask questions about what is being said and who is saying it. The following is a list of typical questions we may ask, along with an evaluation of the ideas in Shonda’s speech.

Is the speaker credible?

Yes. While Shonda may not be an expert per se on the issue of health benefits related to wine, she has made herself a mini-expert through conducting research.

Does the statement ring true or false based on common sense?

It sounds kind of fishy. Four or more glasses of wine in one sitting doesn’t seem right. In fact, it seems like it might be bordering on binge drinking.

Does the logic employed hold up to scrutiny?

Based on the little bit of Shonda’s speech we see here, her logic does seem to be sound. As we will see later on, she actually commits a few fallacies.

What questions or objections are raised by the message?

In addition to the possibility of Shonda’s proposal being binge drinking, it also raises the possibility of creating alcoholism or causing other long term health problems.

How will further information affect the message?

More information will probably contradict her claims. In fact, most medical research in this area contradicts the claim that drinking 4 or more glasses of wine a day is a good thing.

Will further information strengthen or weaken the claims?

Most likely Shonda’s claims will be weakened.

What questions or objections are raised by the claims?

In addition to the objections we’ve already discussed, there is also the problem of the credibility of Shonda’s expert “doctor.”

A wise man proportions his belief to the evidence. ~ David Hume

inference and interpretation or explanation

The next step in critically examining a message is to interpret or explain the conclusions that we draw from it. At this phase we consider the evidence and the claims together. In effect we are reassembling the components that we parsed out during analysis. We are continuing our evaluation by looking at the evidence, alternatives, and possible conclusions.

Before we draw any inferences or attempt any explanations, we should look at the evidence provided. When we consider evidence we must first determine what, if any, kind of support is provided. Of the evidence we then ask:

• Is the evidence sound?
• Does the evidence say what the speaker says it does?
• Does contradictory evidence exist?
• Is the evidence from a valid credible source?

Even though these are set up as yes or no questions, you’ll probably find in practice that your answers are a bit more complex. For example, let’s say you’re writing a speech on why we should wear our seatbelts at all times while driving. You’ve researched the topic and found solid, credible information setting forth the numerous reasons why wearing a seatbelt can help save your life and decrease the number of injuries experienced during a motor vehicle accident. Certainly, there exists contradictory evidence arguing seat belts can cause more injuries. For example, if you’re in an accident where your car is partially submerged in water, wearing a seatbelt may impede your ability to quickly exit the vehicle. Does the fact that this evidence exists negate your claims? Probably not, but you need to be thorough in evaluating and considering how you use your evidence.

“Imply” or “Infer”?

For two relatively small words, imply and infer seem to generate an inordinately large amount of confusion. Understanding the difference between the two and knowing when to use the right one is not only a useful skill, but it also makes you sound a lot smarter!

Let’s begin with imply. Imply means to suggest or convey an idea. A speaker or a piece of writing implies things. For example, in Shonda’s speech, she implies it is better to drink more red wine. In other words, she never directly says that we need to drink more red wine, but she clearly hints at it when she suggests that drinking four or more glasses a day will provide us with health benefits.

Now let’s consider infer. Infer means that something in a speaker’s words or a piece of writing helps us to draw a conclusion outside of his/her words. We infer a conclusion. Returning to Shonda’s speech, we can infer she would want us to drink more red wine rather than less. She never comes right out and says this. However, by considering her overall message, we can draw this conclusion.

• Another way to think of the difference between imply and infer is:
• A speaker (or writer for that matter) implies.
• The audience infers.

Therefore, it would be incorrect to say that Shonda infers we should drink more rather than less wine. She implies this. To help you differentiate between the two, remember that an inference is something that comes from outside the spoken or written text.

A man who does not think for himself does not think at all. ~ Oscar Wilde

self-regulation

The final step in critically examining a message is actually a skill we should exercise throughout the entire process. With self-regulation, we consider our pre-existing thoughts on the subject and any biases we may have. We examine how what we think on an issue may have influenced the way we understand (or think we understand) the message and any conclusions we have drawn. Just as contradictory evidence doesn’t automatically negate our claims or invalidate our arguments, our biases don’t necessarily make our conclusions wrong. The goal of practicing self- regulation is not to disavow or deny our opinions. The goal is to create distance between our opinions and the messages we evaluate.

the value of critical thinking

In public speaking, the value of being a critical thinker cannot be overstressed. Critical thinking helps us to determine the truth or validity of arguments. However, it also helps us to formulate strong arguments for our speeches. Exercising critical thinking at all steps of the speech writing and delivering process can help us avoid situations like Shonda found herself in. Critical thinking is not a magical panacea that will make us super speakers. However, it is another tool that we can add to our speech toolbox.

As we will learn in the following pages, we construct arguments based on logic. Understanding the ways logic can be used and possibly misused is a vital skill. To help stress the importance of it, the Foundation for Critical Thinking has set forth universal standards of reasoning. These standards can be found in Table \(\PageIndex{3}\).

When the mind is thinking, it is talking to itself. ~ Plato

A Crash Course in Critical Thinking

What you need to know—and read—about one of the essential skills needed today..

Posted April 8, 2024 | Reviewed by Michelle Quirk

• In research for "A More Beautiful Question," I did a deep dive into the current crisis in critical thinking.
• Many people may think of themselves as critical thinkers, but they actually are not.
• Here is a series of questions you can ask yourself to try to ensure that you are thinking critically.

Conspiracy theories. Inability to distinguish facts from falsehoods. Widespread confusion about who and what to believe.

These are some of the hallmarks of the current crisis in critical thinking—which just might be the issue of our times. Because if people aren’t willing or able to think critically as they choose potential leaders, they’re apt to choose bad ones. And if they can’t judge whether the information they’re receiving is sound, they may follow faulty advice while ignoring recommendations that are science-based and solid (and perhaps life-saving).

Moreover, as a society, if we can’t think critically about the many serious challenges we face, it becomes more difficult to agree on what those challenges are—much less solve them.

On a personal level, critical thinking can enable you to make better everyday decisions. It can help you make sense of an increasingly complex and confusing world.

In the new expanded edition of my book A More Beautiful Question ( AMBQ ), I took a deep dive into critical thinking. Here are a few key things I learned.

First off, before you can get better at critical thinking, you should understand what it is. It’s not just about being a skeptic. When thinking critically, we are thoughtfully reasoning, evaluating, and making decisions based on evidence and logic. And—perhaps most important—while doing this, a critical thinker always strives to be open-minded and fair-minded . That’s not easy: It demands that you constantly question your assumptions and biases and that you always remain open to considering opposing views.

In today’s polarized environment, many people think of themselves as critical thinkers simply because they ask skeptical questions—often directed at, say, certain government policies or ideas espoused by those on the “other side” of the political divide. The problem is, they may not be asking these questions with an open mind or a willingness to fairly consider opposing views.

When people do this, they’re engaging in “weak-sense critical thinking”—a term popularized by the late Richard Paul, a co-founder of The Foundation for Critical Thinking . “Weak-sense critical thinking” means applying the tools and practices of critical thinking—questioning, investigating, evaluating—but with the sole purpose of confirming one’s own bias or serving an agenda.

In AMBQ , I lay out a series of questions you can ask yourself to try to ensure that you’re thinking critically. Here are some of the questions to consider:

• Why do I believe what I believe?
• Are my views based on evidence?
• Have I fairly and thoughtfully considered differing viewpoints?
• Am I truly open to changing my mind?

Of course, becoming a better critical thinker is not as simple as just asking yourself a few questions. Critical thinking is a habit of mind that must be developed and strengthened over time. In effect, you must train yourself to think in a manner that is more effortful, aware, grounded, and balanced.

For those interested in giving themselves a crash course in critical thinking—something I did myself, as I was working on my book—I thought it might be helpful to share a list of some of the books that have shaped my own thinking on this subject. As a self-interested author, I naturally would suggest that you start with the new 10th-anniversary edition of A More Beautiful Question , but beyond that, here are the top eight critical-thinking books I’d recommend.

The Demon-Haunted World: Science as a Candle in the Dark , by Carl Sagan

This book simply must top the list, because the late scientist and author Carl Sagan continues to be such a bright shining light in the critical thinking universe. Chapter 12 includes the details on Sagan’s famous “baloney detection kit,” a collection of lessons and tips on how to deal with bogus arguments and logical fallacies.

Clear Thinking: Turning Ordinary Moments Into Extraordinary Results , by Shane Parrish

The creator of the Farnham Street website and host of the “Knowledge Project” podcast explains how to contend with biases and unconscious reactions so you can make better everyday decisions. It contains insights from many of the brilliant thinkers Shane has studied.

Good Thinking: Why Flawed Logic Puts Us All at Risk and How Critical Thinking Can Save the World , by David Robert Grimes

A brilliant, comprehensive 2021 book on critical thinking that, to my mind, hasn’t received nearly enough attention . The scientist Grimes dissects bad thinking, shows why it persists, and offers the tools to defeat it.

Think Again: The Power of Knowing What You Don't Know , by Adam Grant

Intellectual humility—being willing to admit that you might be wrong—is what this book is primarily about. But Adam, the renowned Wharton psychology professor and bestselling author, takes the reader on a mind-opening journey with colorful stories and characters.

Think Like a Detective: A Kid's Guide to Critical Thinking , by David Pakman

The popular YouTuber and podcast host Pakman—normally known for talking politics —has written a terrific primer on critical thinking for children. The illustrated book presents critical thinking as a “superpower” that enables kids to unlock mysteries and dig for truth. (I also recommend Pakman’s second kids’ book called Think Like a Scientist .)

Rationality: What It Is, Why It Seems Scarce, Why It Matters , by Steven Pinker

The Harvard psychology professor Pinker tackles conspiracy theories head-on but also explores concepts involving risk/reward, probability and randomness, and correlation/causation. And if that strikes you as daunting, be assured that Pinker makes it lively and accessible.

How Minds Change: The Surprising Science of Belief, Opinion and Persuasion , by David McRaney

David is a science writer who hosts the popular podcast “You Are Not So Smart” (and his ideas are featured in A More Beautiful Question ). His well-written book looks at ways you can actually get through to people who see the world very differently than you (hint: bludgeoning them with facts definitely won’t work).

A Healthy Democracy's Best Hope: Building the Critical Thinking Habit , by M Neil Browne and Chelsea Kulhanek

Neil Browne, author of the seminal Asking the Right Questions: A Guide to Critical Thinking, has been a pioneer in presenting critical thinking as a question-based approach to making sense of the world around us. His newest book, co-authored with Chelsea Kulhanek, breaks down critical thinking into “11 explosive questions”—including the “priors question” (which challenges us to question assumptions), the “evidence question” (focusing on how to evaluate and weigh evidence), and the “humility question” (which reminds us that a critical thinker must be humble enough to consider the possibility of being wrong).

In this article, we will explain 9 strategies that any motivated person can use to develop as a thinker. As we explain the strategy, we will describe it as if we were talking directly to such a person. Further details to our descriptions may need to be added for those who know little about critical thinking. Here are the 9:

There is nothing magical about our ideas. No one of them is essential. Nevertheless, each represents a plausible way to begin to do something concrete to improve thinking in a regular way. Though you probably can’t do all of these at the same time, we recommend an approach in which you experiment with all of these over an extended period of time.

First Strategy: Use “Wasted” Time. All humans waste some time; that is, fail to use all of their time productively or even pleasurably. Sometimes we jump from one diversion to another, without enjoying any of them. Sometimes we become irritated about matters beyond our control. Sometimes we fail to plan well causing us negative consequences we could easily have avoided (for example, we spend time unnecessarily trapped in traffic — though we could have left a half hour earlier and avoided the rush). Sometimes we worry unproductively. Sometimes we spend time regretting what is past. Sometimes we just stare off blankly into space.

The key is that the time is “gone” even though, if we had thought about it and considered our options, we would never have deliberately spent our time in the way we did. So why not take advantage of the time you normally waste by practicing your critical thinking during that otherwise wasted time? For example, instead of sitting in front of the TV at the end of the day flicking from channel to channel in a vain search for a program worth watching, spend that time, or at least part of it, thinking back over your day and evaluating your strengths and weaknesses. For example, you might ask yourself questions like these:

When did I do my worst thinking today? When did I do my best? What in fact did I think about today? Did I figure anything out? Did I allow any negative thinking to frustrate me unnecessarily? If I had to repeat today what would I do differently? Why? Did I do anything today to further my long-term goals? Did I act in accordance with my own expressed values? If I spent every day this way for 10 years, would I at the end have accomplished something worthy of that time?

It would be important of course to take a little time with each question. It would also be useful to record your observations so that you are forced to spell out details and be explicit in what you recognize and see. As time passes, you will notice patterns in your thinking. Second Strategy: A Problem A Day. At the beginning of each day (perhaps driving to work or going to school) choose a problem to work on when you have free moments. Figure out the logic of the problem by identifying its elements. In other words, systematically think through the questions: What exactly is the problem? How can I put it into the form of a question. How does it relate to my goals, purposes, and needs?

Third Strategy: Internalize Intellectual Standards. Each week, develop a heightened awareness of one of the universal intellectual standards (clarity, precision, accuracy, relevance, depth, breadth, logicalness, significance). Focus one week on clarity, the next on accuracy, etc. For example, if you are focusing on clarity for the week, try to notice when you are being unclear in communicating with others. Notice when others are unclear in what they are saying.

When you are reading, notice whether you are clear about what you are reading. When you orally express or write out your views (for whatever reason), ask yourself whether you are clear about what you are trying to say. In doing this, of course, focus on four techniques of clarification : 1) Stating what you are saying explicitly and precisely (with careful consideration given to your choice of words), 2) Elaborating on your meaning in other words, 3) Giving examples of what you mean from experiences you have had, and 4) Using analogies , metaphors, pictures, or diagrams to illustrate what you mean. In other words, you will frequently STATE, ELABORATE, ILLUSTRATE, AND EXEMPLIFY your points. You will regularly ask others to do the same.

Fourth Strategy: Keep An Intellectual Journal. Each week, write out a certain number of journal entries. Use the following format (keeping each numbered stage separate):

Strategy Five: Reshape Your Character. Choose one intellectual trait---intellectual perseverance, autonomy, empathy, courage, humility, etc.--- to strive for each month, focusing on how you can develop that trait in yourself. For example, concentrating on intellectual humility, begin to notice when you admit you are wrong. Notice when you refuse to admit you are wrong, even in the face of glaring evidence that you are in fact wrong. Notice when you become defensive when another person tries to point out a deficiency in your work, or your thinking. Notice when your intellectual arrogance keeps you from learning, for example, when you say to yourself “I already know everything I need to know about this subject.” Or, “I know as much as he does. Who does he think he is forcing his opinions on me?” By owning your “ignorance,” you can begin to deal with it.

Strategy Six: Deal with Your Egocentrism. Egocentric thinking is found in the disposition in human nature to think with an automatic subconscious bias in favor of oneself. On a daily basis, you can begin to observe your egocentric thinking in action by contemplating questions like these: Under what circumstances do I think with a bias in favor of myself? Did I ever become irritable over small things? Did I do or say anything “irrational” to get my way? Did I try to impose my will upon others? Did I ever fail to speak my mind when I felt strongly about something, and then later feel resentment? Once you identify egocentric thinking in operation, you can then work to replace it with more rational thought through systematic self-reflection, thinking along the lines of: What would a rational person feel in this or that situation? What would a rational person do? How does that compare with what I want to do? (Hint: If you find that you continually conclude that a rational person would behave just as you behaved you are probably engaging in self-deception.)

Strategy Seven: Redefine the Way You See Things . We live in a world, both personal and social, in which every situation is “defined,” that is, given a meaning. How a situation is defined determines not only how we feel about it, but also how we act in it, and what implications it has for us. However, virtually every situation can be defined in more than one way. This fact carries with it tremendous opportunities. In principle, it lies within your power and mine to make our lives more happy and fulfilling than they are. Many of the negative definitions that we give to situations in our lives could in principle be transformed into positive ones. We can be happy when otherwise we would have been sad.

We can be fulfilled when otherwise we would have been frustrated. In this strategy, we practice redefining the way we see things, turning negatives into positives, dead-ends into new beginnings, mistakes into opportunities to learn. To make this strategy practical, we should create some specific guidelines for ourselves. For example, we might make ourselves a list of five to ten recurrent negative contexts in which we feel frustrated, angry, unhappy, or worried. We could then identify the definition in each case that is at the root of the negative emotion. We would then choose a plausible alternative definition for each and then plan for our new responses as well as new emotions. For example, if you tend to worry about all problems, both the ones you can do something about and those that you can’t; you can review the thinking in this nursery rhyme: “For every problem under the sun, there is a solution or there is none. If there be one, think til you find it. If there be none, then never mind it.”

Let’s look at another example. You do not have to define your initial approach to a member of the opposite sex in terms of the definition “his/her response will determine whether or not I am an attractive person.” Alternatively, you could define it in terms of the definition “let me test to see if this person is initially drawn to me—given the way they perceive me.” With the first definition in mind, you feel personally put down if the person is not “interested” in you; with the second definition you explicitly recognize that people respond not to the way a stranger is, but the way they look to them subjectively. You therefore do not take a failure to show interest in you (on the part of another) as a “defect” in you.

Strategy Eight: Get in touch with your emotions: Whenever you feel some negative emotion, systematically ask yourself: What, exactly, is the thinking leading to this emotion? For example, if you are angry, ask yourself, what is the thinking that is making me angry? What other ways could I think about this situation? For example, can you think about the situation so as to see the humor in it and what is pitiable in it? If you can, concentrate on that thinking and your emotions will (eventually) shift to match it.

Strategy Nine: Analyze group influences on your life: Closely analyze the behavior that is encouraged, and discouraged, in the groups to which you belong. For any given group, what are you "required" to believe? What are you "forbidden" to do? Every group enforces some level of conformity. Most people live much too much within the view of themselves projected by others. Discover what pressure you are bowing to and think explicitly about whether or not to reject that pressure.

Conclusion: The key point to keep in mind when devising strategies is that you are engaged in a personal experiment. You are testing ideas in your everyday life. You are integrating them, and building on them, in the light of your actual experience. For example, suppose you find the strategy “Redefine the Way You See Things” to be intuitive to you. So you use it to begin. Pretty soon you find yourself noticing the social definitions that rule many situations in your life. You recognize how your behavior is shaped and controlled by the definitions in use:

• “I’m giving a party,” (Everyone therefore knows to act in a “partying” way)
• “The funeral is Tuesday,” (There are specific social behaviors expected at a funeral)
• “Jack is an acquaintance, not really a friend.” (We behave very differently in the two cases)

You begin to see how important and pervasive social definitions are. You begin to redefine situations in ways that run contrary to some commonly accepted definitions. You notice then how redefining situations (and relationships) enables you to “Get in Touch With Your Emotions.” You recognize that the way you think (that is, define things) generates the emotions you experience. When you think you are threatened (i.e., define a situation as “threatening”), you feel fear. If you define a situation as a “failure,” you may feel depressed. On the other hand, if you define that same situation as a “lesson or opportunity to learn” you feel empowered to learn. When you recognize this control that you are capable of exercising, the two strategies begin to work together and reinforce each other.

Next consider how you could integrate strategy #9 (“Analyze group influences on your life”) into your practice. One of the main things that groups do is control us by controlling the definitions we are allowed to operate with. When a group defines some things as “cool” and some as “dumb, ” the members of the group try to appear “cool” and not appear “dumb.” When the boss of a business says, “That makes a lot of sense,” his subordinates know they are not to say, “No, it is ridiculous.” And they know this because defining someone as the “boss” gives him/her special privileges to define situations and relationships.

You now have three interwoven strategies: you “Redefine the Way You See Things,” “Get in touch with your emotions,” and “Analyze group influences on your life.” The three strategies are integrated into one. You can now experiment with any of the other strategies, looking for opportunities to integrate them into your thinking and your life. If you follow through on some plan analogous to what we have described, you are developing as a thinker. More precisely, you are becoming a “Practicing” Thinker. Your practice will bring advancement. And with advancement, skilled and insightful thinking may becomes more and more natural to you.

Critical thinking has become an invaluable skill in a world overflowing with information. It’s not just about analyzing arguments or solving problems; it’s a way of approaching life more logically and thoughtfully. But what makes someone a critical thinker? What are the characteristics that set them apart?

In this article, we delve into the minds of critical thinkers and uncover the 18 essential characteristics that define them. From curiosity and open-mindedness to skepticism and intellectual humility, we explore the traits that shape their thought process and decision-making abilities. We’ll also discuss the importance of critical thinking in various aspects of life, from personal relationships to professional success.

Whether you’re a student preparing for exams, a business professional making important decisions, or simply someone looking to enhance your cognitive skills, this article will provide valuable insights and tips to unlock the power of critical thinking. So join us on this journey of exploration as we unravel the mysteries of the critical thinker’s mind and inspire you to cultivate these essential characteristics for a more meaningful and successful life.

1. Open-Mindedness: The Cornerstone of Critical Thought

Open-mindedness stands out as a defining characteristic in the realm of critical thinking. This willingness to entertain various perspectives, ideas, and opinions without rushing to judgment is not merely a trait but a foundational pillar. But what makes open-mindedness so crucial in the framework of critical thought? An individual with a truly open mind doesn’t hastily dismiss ideas, especially if they’re novel or unfamiliar. Instead, they perceive them as opportunities – gateways to deeper learning, understanding, and personal growth. Everyone possesses inherent biases; it’s part of the human condition. However, an open-minded individual actively works to rise above these biases. This conscious effort becomes indispensable in our diverse global landscape, where interactions span various backgrounds and cultures.

Moreover, open-mindedness speaks to a certain flexibility in one’s beliefs. While holding onto certain beliefs is a natural human inclination, the open-minded are ever ready to reevaluate and recalibrate their beliefs in light of fresh evidence or alternative viewpoints. This adaptability doesn’t suggest fickleness but indicates a profound dedication to the pursuit of truth, even if it necessitates altering one’s stance. Additionally, these individuals have a heightened appreciation for the diversity of thought, recognizing how varied viewpoints can infuse discussions with rich insights, facilitate holistic problem-solving, and even be the catalysts for innovation.

One of the common pitfalls in reasoning is confirmation bias, a trap of only seeking information that aligns with our existing beliefs. Open-minded thinkers, however, remain vigilant against this bias. They actively pursue diverse sources and perspectives to gain a rounded understanding. This open-minded stance is frequently paired with an inherent curiosity. They commonly say, “I don’t have all the answers,” or “Let’s delve deeper into this,” highlighting their willingness to probe further into subjects and discussions. They also acknowledge the fluid nature of knowledge. In our ever-shifting world, they recognize that absolute certainty is elusive. They are comfortable navigating the ambiguities, understanding that most knowledge is tentative and evolving.

In essence, open-mindedness goes beyond mere passive acceptance. It’s a dynamic journey, a continuous commitment to shedding preconceived notions and embracing the broad array of ideas and perspectives the world presents. For those walking the path of critical thinking, open-mindedness is the starting point, paving the way for unbiased assessment, profound comprehension, and enlightened decision-making.

2. Curiosity: A natural inclination to question, explore, and understand deeper insights about a subject.

Diving deeper into the characteristics of critical thinkers, Curiosity stands out prominently. Often described as an insatiable thirst for knowledge, it serves as the driving force propelling critical thinkers forward in their intellectual quests. The importance of curiosity in critical thinking cannot be overstated. It’s reflected in the behavior and mindset of those who never cease to question and explore. This trait’s essence is an innate desire to learn, not driven by external rewards but by a profound intrinsic motivation to understand the world better.

Unlike many who might accept information as it’s presented, those fueled by curiosity have a restless mind. They are the ones challenging the status quo, continually asking questions like “Why?”, “How?”, and “What if?”. Such probing often leads them to challenge established norms, providing them with deeper insights and a more profound understanding. This drive pushes them beyond mere surface-level knowledge. They strive to get to the root of issues, taking the time to research, analyze, and reflect upon complex topics.

Moreover, their curiosity isn’t confined to just academic or intellectual arenas. It spills over into their daily lives, leading them to seek diverse experiences. They are stepping out of their comfort zones, eager to immerse themselves in new cultures or try out unfamiliar activities. Each of these experiences, they believe, adds a new layer to their understanding of the world. The unknown, which might deter many, is a beckoning call for them. They approach uncertainty with excitement, seeing it not as a hindrance but as a golden opportunity for discovery.

Such individuals also stand out in their engagement with information. Rather than being passive consumers, they actively engage with content. They reflect on ideas, discuss them with peers, and even engage in healthy debates to refine their understanding further. This constant quest for knowledge, however, doesn’t make them overconfident. They remain cautious, aware of the pitfalls of assumptions. Aware that every learning journey has its dangers, they ensure they don’t fall prey to presuming they have complete knowledge about a subject. This humility and their insatiable desire for understanding make them value lifelong learning. They don’t see the end of formal education as the end of their learning journey. Instead, they embrace every opportunity to expand their horizons, irrespective of where they are in their life or career.

Curiosity isn’t just another trait on a list; it’s a dynamic, ever-present force shaping a critical thinker’s very approach and outlook. It keeps them engaged, pushes them to explore varied avenues, and ensures they approach the world with humility and receptiveness; fostering and cherishing their curiosity is crucial for anyone keen on sharpening their critical thinking abilities.

3. Analytical Ability: Can dissect complex ideas or problems to understand their components.

Within the vast landscape of critical thinking, analytical ability emerges as a paramount pillar. It’s far more than a mere grasp of concepts or problems. Rather, it signifies the capacity to delve beneath the surface, fragmenting intricate issues into their elemental parts, revealing a nuanced understanding. Analytical thinkers are distinguished by their systematic approach, systematically dissecting situations to discern underlying patterns. In our data-saturated world, their aptitude for sifting essential information from the cacophony stands invaluable.

This leads to clarity and enables a holistic comprehension, ensuring each fragment is evaluated within the context of the larger tapestry. Such an approach greatly amplifies their problem-solving prowess, directing them toward the root of issues rather than mere symptoms. When faced with choices, this intricate understanding capacitates them to make well-informed decisions, gauging potential challenges and rewards. Their analytical strength also shines in communication, enabling them to elucidate complex concepts with clarity and persuasion.

This mindset invariably fuels their insatiable curiosity, urging them to bridge knowledge gaps and expand their horizons continuously. Furthermore, their ability to promptly dissect and adapt to new challenges becomes invaluable in our dynamic world. Analytical ability isn’t just a skill but a unique prism that enhances a critical thinker’s view of the world. This prism reveals hidden layers and connections, allowing for profound insights, fostering innovation, and engendering a deeper, more engaged interaction with intricate worldly challenges.

4. Logical Reasoning: The Structured Pathway to Sound Decisions

In the intricate maze of problem-solving and decision-making, logical reasoning is the guiding light, illuminating the path toward clarity and coherence. Unlike impulsive or emotion-driven approaches, logical reasoning epitomizes a methodical, step-by-step progression that ensures every decision or solution is rooted in reason and evidence.

At its core, logical reasoning is a marriage of structured thought processes and evidence-based conclusions. A thinker employing this approach will meticulously evaluate each piece of information, considering its relevance and validity. This discernment allows them to discard irrelevant or misleading data, ensuring that only the most pertinent facts shape their conclusions.

Furthermore, the structured nature of logical reasoning mandates the identification of cause-and-effect relationships. This means that the thinker anticipates potential outcomes and consequences before arriving at a solution or decision, weighing the pros and cons methodically. Such foresight minimizes unforeseen setbacks and strengthens the viability of the chosen solution or decision.

Additionally, logical reasoning is self-correcting. By consistently questioning and validating each step in their thought process, individuals are less likely to be swayed by cognitive biases or fallacies. If an inconsistency or error is spotted, they can trace their steps, pinpoint the flaw, and recalibrate their approach.

In essence, logical reasoning is not just a tool but an anchor, grounding critical thinkers in a realm of rationality and coherence. In a world teeming with information and complexity, this methodical approach stands as a beacon, guiding thinkers away from the pitfalls of hasty judgments and towards well-founded, robust conclusions. For anyone striving to master the art of critical thinking, honing their logical reasoning skills is not merely advantageous—it’s indispensable.

5. Attention to Detail: Unearthing Nuances in the Tapestry of Complexity

Amidst the vast expanse of information and stimuli we encounter daily, the ability to discern subtle details can be a transformative power. Attention to detail is much more than just observational prowess; it’s an art of recognizing the intricate stitches that, while seemingly insignificant on their own, form the fabric of larger narratives and problems.

A person endowed with keen attention to detail doesn’t merely skim the surface. They delve deeper, sifting through layers of information, discerning patterns and irregularities that might escape the cursory glance of many. It’s akin to a jeweler who, amidst the glitter of a gem-studded necklace, identifies one slightly flawed diamond that could compromise the entire piece’s value.

This trait is invaluable across myriad contexts. In analytical pursuits, for instance, noticing a minor discrepancy in data can be the key to unearthing larger issues or breakthrough insights. It could be the difference between a masterpiece and mediocrity in creative fields, as details breathe life and authenticity into artworks or narratives.

Moreover, acute attention to detail often translates into higher accuracy and efficiency. One can prevent larger complications or misunderstandings by catching errors or anomalies early on. It’s a proactive approach, eliminating the need for extensive revisions or damage control later.

Yet, it’s also essential to understand that this attribute isn’t about nitpicking or getting bogged down by minutiae. Instead, it’s about balancing recognizing subtleties and grasping the broader perspective. It’s the dance between the macro and the micro, ensuring neither is overlooked.

In conclusion, attention to detail is a compass in a world of information and distractions. It steers individuals towards clarity, precision, and excellence, making them stand out in a crowd where many are content with just seeing the bigger picture. For those aspiring to elevate their thinking and work to unprecedented heights, cultivating this discerning eye for detail is not just beneficial—it’s pivotal.

6. Skepticism: The Guardian of Authentic Knowledge

In an era overflowing with information, where digital platforms and media constantly bombard us with narratives, facts, and viewpoints, skepticism emerges as a crucial shield against misinformation and shallow understanding. Far from being a sign of cynicism or distrust, skepticism is a rigorous intellectual stance, urging individuals to pause, probe, and ponder before accepting any information.

A true skeptic does not dismiss information outright. Instead, they approach it with a discerning mind, evaluating its source, scrutinizing its context, and cross-referencing it with other reliable data. Such a perspective stems from an understanding that even well-intentioned sources can err, and even widely accepted beliefs can sometimes be misguided or incomplete.

This attitude is particularly invaluable in today’s “post-truth” world, where emotional or sensational narratives often overshadow factual accuracy. Skepticism is a filter helping individuals differentiate between genuine knowledge and mere noise. It pushes them to go beyond the surface, to trace the origins of claims, and to weigh them against empirical evidence.

Moreover, skepticism nurtures a proactive mindset. Instead of passively absorbing information, skeptics actively engage with it, raising questions, spotting inconsistencies, and seeking clarifications. This ensures they gather authentic knowledge and deepens their understanding of the subject at hand.

But it’s also worth noting that skepticism, while invaluable, must be balanced with an openness to new ideas. It should not morph into stubborn disbelief or close-mindedness. Rather, it should serve as a tool for rigorous evaluation, ensuring that the knowledge one acquires is robust and reliable.

In essence, skepticism is not a barrier but a beacon in the pursuit of truth. It challenges us to elevate our standards of acceptance, demand evidence, and never settle for the superficial. For those committed to genuine understanding and informed decision-making, cultivating a healthy skepticism is not just an asset—it’s a necessity.

7. Clear Communication: The Bridge Between Thought and Understanding

Clear communication emerges as the choreographer in the intricate dance of ideas, arguments, and insights that define our interpersonal and intellectual interactions. It is the channel through which complex concepts flow, are understood, and eventually take shape in the minds of others. But what does it truly mean to communicate clearly, and why is it such an essential facet of a well-rounded thinker?

At its core, clear communication is about transcending mere information transfer. It’s about ensuring that the essence of an idea, with all its subtleties and nuances, is accurately and effectively conveyed. This requires linguistic proficiency and a deep empathy for the listener’s perspective. Clear communicators are acutely aware of their audience, tailoring their message to suit the listener’s background, level of understanding, and potential biases.

Several dimensions define this art:

• Simplicity: While it’s tempting to use jargon or complex language, especially when discussing intricate topics, clear communication often thrives in simplicity. It’s about breaking down complex ideas into digestible, relatable chunks.
• Structure: An organized flow of thoughts, with a clear beginning, middle, and end, aids comprehension. Clear communicators are adept at sequencing their points logically, guiding their audience through the narrative.
• Relevance: Effective communicators ensure their message remains potent and undiluted by staying on topic and avoiding tangential diversions.
• Feedback: Interactivity is a hallmark of clear communication. By encouraging questions, seeking clarifications, and being receptive to feedback, communicators can ensure their message lands as intended.
• Visual Aids: Whether it’s a simple diagram, a comprehensive infographic, or a vivid analogy, visual or descriptive tools can dramatically enhance understanding, bridging gaps that words alone might leave behind.
• Empathy: Understanding and anticipating the audience’s needs, doubts, or potential misconceptions allows a communicator to address them proactively, fostering a deeper connection and comprehension.

Clear communication stands out as a beacon of clarity in a world filled with noise, ambiguity, and information overload. It’s more than just a skill—it’s a responsibility, ensuring that ideas reach others and truly resonate. For anyone aspiring to influence, educate, or connect on a deeper level, mastering the art of clear communication is an investment that pays immeasurable dividends.

8. Problem-Solving: The Systematic Unraveling of Challenges

In the vast and intricate landscape of skills required to navigate our world, problem-solving firmly establishes itself as an indispensable cornerstone. This prowess extends beyond mere solution-seeking; it delves deep, aiming to understand, dissect, and craft enduring resolutions to challenges. But how does one truly master this art, and what role does it play in the broader spectrum of critical thinking?

Envision problem-solving as an orchestra of cognitive processes seamlessly converging toward a singular goal. It resembles a detective’s diligence in piecing together seemingly unrelated clues. The journey of a proficient problem solver begins with clearly identifying the problem, differentiating between mere symptoms and the core issue. This clarity paves the way for gathering pertinent data, ensuring a comprehensive understanding of the challenge.

As this information is sifted through, patterns are discerned, leading to the crystallization of potential solutions. Rather than settling for a single answer, multiple pathways are assessed for pros and cons. Armed with these alternatives, they employ logical reasoning to zero in on the most practical solution, always mindful of its broader implications. Once decided, the focus shifts to the effective implementation of this solution. However, the process doesn’t end there; a genuine problem solver consistently evaluates the solution’s efficacy, making necessary adjustments.

In life’s grand puzzle filled with diverse challenges, a methodical approach to problem-solving transforms daunting hurdles into solvable mysteries. This skill provides solutions and nurtures confidence, resilience, and proactive thinking — traits vital in all endeavors. Those who aspire to leave a mark, professionally and personally, will find sharpening their problem-solving acumen to be a pursuit of unparalleled worth.

9. Objectivity: Navigating Truth Beyond Personal Filters

In the vast landscape of critical thinking, the significance of Objectivity is undeniable. Living in an era of information and many viewpoints, our need for a reliable compass—a tool that helps us distinguish truth from falsehood—has never been more pronounced. Objectivity emerges as that guiding compass. But what does it entail?

To truly grasp the essence of objectivity, one must see it as an art of discerning truth without being ensnared by personal emotions, biases, or preconceived notions. It’s about achieving a vantage point, a place from which things can be seen for what they are, devoid of personal coloring or distortion.

An individual rooted in objectivity doesn’t blindly embrace any piece of information. Instead, they prioritize evidence-based facts, sidelining unverified claims or mere anecdotes. This meticulous approach ensures that their decisions and beliefs are anchored firmly in truth. Emotional intelligence plays a part too. While emotions are integral to our humanity, they can sometimes muddy the waters of clear thinking. Objective thinkers possess the astuteness to acknowledge their feelings without letting them skew the interpretation of facts.

The world isn’t black and white; it’s a kaleidoscope of experiences and backgrounds. Each person’s life story comes with its unique set of biases. Recognizing and addressing these inherent biases is a hallmark of the objective thinker. They actively seek multiple perspectives, understanding that a multifaceted approach often leads to a richer, more comprehensive grasp of issues. This openness also extends to their informational sources. They strive to diversify, ensuring they don’t become ensnared in echo chambers that merely echo back their existing beliefs.

Perhaps one of the most notable traits of objective individuals is their unwavering commitment to the truth. They’re not rigidly attached to their beliefs. They’re more than willing to adapt when presented with compelling evidence that challenges their stance, highlighting their ceaseless quest for genuine understanding. In today’s era, where “opinionated facts” often blur the lines between evidence and mere opinion, objectivity is a bastion of reason and clarity.

Objectivity isn’t just a skill—it’s a guiding philosophy. It serves as a beacon, illuminating the path for critical thinkers amidst the storms of misinformation, bias, and emotional upheaval. By emphasizing clear, unbiased thinking, objectivity ensures that our journey through this intricate, interconnected world is rooted in truth and clarity. Those who truly wish to engage with the world’s complexities would do well to embrace and nurture their objective thinking, for it promises clarity and a deeper, more genuine connection with the world around them.

10. Empathy: Bridging Minds and Hearts in Critical Thought

In discussions about critical thinking, one might not immediately think of empathy as a cornerstone. Yet, this emotion-driven quality finds its strength in the world of feelings and rigorous analytical thinking. Critical thinking, while primarily governed by logic and objectivity, finds profound enhancement when paired with the deep understanding inherent to empathy. So, why is empathy invaluable in critical reasoning? Empathy goes beyond mere sympathy.

It is the profound ability to wear the shoes of another, deeply understanding their perspectives, emotions, and lived experiences. This capability of genuine understanding offers many advantages to the discerning mind. For one, it permits a richer and more nuanced understanding of matters, tapping into the underlying intricacies that a single perspective might overlook. Empathy also paves the way for more effective communication.

Discussions transform into more constructive exchanges when we approach dialogue with an understanding heart. It also plays a vital role in curbing biases. By immersing ourselves in diverse perspectives, we are more equipped to challenge and rectify our inherent biases. This empathetic approach drives more inclusive decision-making, ensuring that choices are well-rounded, considering all stakeholders involved. Moreover, in situations of disagreement, empathy proves to be an unparalleled tool, assisting in pinpointing shared grounds and crafting mutually beneficial solutions.

Engaging empathetically also deepens our learning experience. It prods us to continually evaluate our beliefs and grow our understanding, opening us up to a wealth of insights. Furthermore, empathy reminds us of the human stories behind the numbers in a world increasingly leaning towards data and statistics. It ensures that our decision-making, while data-informed, remains human-centric. As we traverse the complexities of today’s interconnected world, the amalgamation of diverse cultures and ideas underscores the need for empathy.

It’s more than just a commendable trait; it’s a vital skill, acting as a bridge that fosters mutual understanding in an often polarized world. In the journey of critical thinking, embedding empathy ensures that the journey is intellectually rich and profoundly humane.

11. Flexibility in Critical Thinking: The Power to Pivot in an Ever-Changing Landscape

Adaptability is a beacon of effective decision-making in our modern, rapidly-evolving era of diverse information. Amidst the overflowing ocean of varied ideas, beliefs, and insights, flexibility emerges — not as an emblem of indecisiveness but as a testament to intellectual maturity. True flexibility in critical thinking transcends mere vacillation between opinions.

Instead, it represents a profound acknowledgment of the dynamic nature of knowledge and an individual’s capacity to recalibrate their perspectives when new, compelling evidence surfaces, even if it juxtaposes their entrenched beliefs.

This intellectual dance encompasses various dimensions: a perpetual commitment to learning, recognizing that enlightenment is an unending journey; an aversion to the constrictions of dogma, valuing the fluid essence of understanding; an insatiable curiosity that fuels exploration beyond the familiar; an appreciation for the mosaic of diverse opinions, understanding that this tapestry lends depth to comprehension; an emotional steadiness that responds to contrasting views with intrigue rather than defensiveness; and, most vitally, unwavering allegiance to truth, even if it demands a humbling shift in stance.

As we chart our course through the intricate maze of knowledge, flexibility becomes our compass — ensuring our navigation is nimble, receptive, and perennially aligned with the quest for profound truths. It embodies not the weakness of being effortlessly influenced but the strength to refine one’s understanding with the expanding vistas of enlightenment.

12. Patience: The Deliberate Pursuit of Depth in Thought

In our age of immediacy, patience emerges as a refreshing, even revolutionary, trait. It stands contrary to our digital landscape’s quick clicks and rapid scrolls, particularly within critical thinking. So, what makes patience so integral, especially when the world often demands immediate answers?

Patience isn’t mere waiting; it’s an intentional deep dive into the ocean of thought, providing the time and space for ideas to germinate and evolve. This considered approach offers discerning thinkers several advantages:

• Depth Over Speed: Rather than skimming the surface, patient thinkers plunge into the depths, uncovering intricacies that might be overlooked in haste.
• Minimizing Mistakes: Rushed judgments can be fraught with errors. By pondering over details, patient thinkers ensure accuracy and thoroughness.
• Comprehensive Insights: Giving thoughts time to simmer allows thinkers to view issues from multiple angles, leading to a rounded understanding.
• Balanced Emotions: Reactivity can cloud judgment. Patience acts as a stabilizing force, ensuring emotions don’t unduly sway decisions.
• Cultivating Curiosity: Patience encourages a journey led by curiosity, where every avenue of thought is explored, and nothing is taken at face value.
• Resilience in Problem-Solving: When faced with knotty challenges, it’s patience that grants thinkers the perseverance to unravel them.
• Clearer Conclusions: Giving ample time for reflection often results in sharper clarity, enabling thinkers to differentiate between the essential and the extraneous.

In a nutshell, patience is the unsung hero of critical thinking. While it may seem counterintuitive in our fast-paced world, patience often leads to the most profound and enduring insights. As thinkers navigate the vast seas of information, this virtue ensures they don’t merely paddle on the surface but dive deep, seeking pearls of wisdom that lie beneath.

13. Self-awareness: The Mirror of Mindful Thinking

Like a dance, critical thinking requires an acute awareness of every step and nuance. In this choreography of the mind, self-awareness stands out as a dancer would attune to their every movement. This isn’t just a venture into the vast expanse of external knowledge but a deep dive inward. This journey uncovers our personal biases and the underlying reasons for our beliefs. So, what makes self-awareness so crucial in our thinking processes?

When we speak of self-awareness, we refer to the introspective lens that illuminates our feelings, beliefs, and inherent biases. It acknowledges our mental processes, triggers, and innate tendencies. This depth of understanding oneself offers many benefits for those dedicated to critical thinking. For starters, it aids in identifying our intellectual blind spots. Even the most objective of us harbor biases, often unbeknownst to us. Recognizing these is the first step towards ensuring they don’t unduly skew our judgments. This self-recognition leads to enhanced objectivity. By being aware of our predispositions, we can tackle issues with a clearer, less biased mind. Furthermore, it helps regulate our emotions, ensuring that while we respect our feelings, we don’t let them cloud our analytical process.

But the journey doesn’t end there. Self-awareness fosters continuous personal and intellectual growth. It’s the driving force behind self-improvement, pushing us to refine our beliefs and actions constantly. When making decisions, an awareness of our biases can help us seek out diverse perspectives, leading to more informed and holistic choices. On a more interpersonal level, understanding ourselves sets the foundation for understanding and empathizing with others, promoting fruitful and empathetic discussions. Additionally, true authenticity in thought springs from self-awareness. It ensures our beliefs are genuine reflections of our understanding, not just molded by societal expectations or external pressures.

To sum it up, self-awareness is not just a tool but the compass for our intellectual journey. In the information age, where we’re bombarded with many opinions and perspectives, self-awareness keeps us anchored. It reminds us to challenge the vast world of external information and regularly question and understand the intricate world within us.

14. Resilience: A Pillar of Critical Thinking in the Face of Challenges

When we delve into the world of critical thinking, resilience emerges as a steadfast anchor, holding firm amidst the turbulent waves of intellectual challenges. It’s more than just a skill; it’s a driving force that empowers thinkers to transform setbacks into springboards for growth. But what role does resilience, a trait so deeply tied to enduring hardships, play in our journey of knowledge?

Resilience, at its core, champions the undeterred pursuit of knowledge. It isn’t just about the journey but an acknowledgment that this journey, filled with its twists, turns, and bumps, is replete with invaluable lessons. What sets a resilient thinker apart?

Such thinkers view failures as invaluable lessons, pivoting from potential dead-ends to deep introspection and learning. They remain staunchly committed to understanding, even when faced with perplexing complexities. Mistakes become growth opportunities, analyzed in depth to ensure they’re not repeated. Their strategy is fluid, always ready to adapt to overcome hurdles. They maintain a broad viewpoint, ensuring temporary challenges don’t detract from their objectives. Their ethos is grounded in a growth mindset, viewing challenges as avenues for intellectual expansion. Beyond this, their emotional resilience keeps them anchored, ensuring that emotional highs and lows don’t deter their quest.

In the intricate world of critical thinking, resilience acts as the binding thread, maintaining the fabric’s coherence and strength. It is a testament to a thinker’s ability to endure and flourish amidst adversity. As they navigate the dense terrains of information, theories, and hypotheses, resilience is their guiding light, reinforcing an ever-evolving quest for knowledge.

15. Humility: The Beacon of Critical Thought

In critical thinking, where myriad traits claim prominence, humility subtly commands respect. It thrives quietly in a society that often conflates boldness with brilliance, making humility’s power even more remarkable. Contrary to conventional thought, this virtue doesn’t indicate feebleness; it’s a testament to intellectual authenticity and a willingness to evolve.

At its core, humility embraces the vastness of knowledge, acknowledging our limited grasp and the infinite lessons awaiting discovery. It’s a gentle nudge, reminding thinkers that true wisdom lies in understanding the scope of what they don’t know. This humbleness in approach drives a continuous hunger for learning, prompting individuals to value varied perspectives, acknowledging that collective insights often eclipse solitary views. Such thinkers, grounded in humility, not only admit their lapses but use them as pivot points for growth.

Their authenticity in admitting errors earns them trust, facilitating enriching dialogues. Moreover, humble thinkers shield themselves against personal biases, ensuring balanced and fair decisions. Their modesty naturally attracts collaboration, fostering a spirit of shared discovery.

But perhaps most crucially, humility is the guardian of a thinker’s sincerity, emphasizing truth over ego, making the intellectual journey not a race to be right but a pursuit of genuine understanding. In an era overflowing with information, humility anchors thinkers, guiding them through the expansive oceans of knowledge, always reminding them that learning is an endless voyage and every individual a constant apprentice.

16. Holistic Thinking: The Art of Seeing Beyond the Pieces

Within the vast panorama of cognitive abilities, holistic thinking shines as a beacon, orchestrating diverse elements into a harmonized whole. This thinking style prompts us to step back and embrace the entire tableau in an era often lost in the details. Rather than merely focusing on isolated fragments, it insists on recognizing their place within the greater mosaic.

Holistic thinkers see landscapes beyond individual trees or streams; they fathom how each element contributes to the collective ecosystem. This breadth of vision equips them to discern intricate relationships, anticipate far-reaching consequences, and cultivate synergies. Such thinkers are not merely addressing the symptoms of issues but delving into their very core, crafting comprehensive solutions that consider the broader context.

Their approach is a testament to the belief that the entirety of a situation often offers insights that its parts cannot. As the modern world inundates us with fragmented information, holistic thinking stands as our guide, ensuring we navigate with a perspective that acknowledges the interwoven intricacies of our complex reality.

17. Active Listening: The Unsung Hero of Effective Communication

In today’s cacophonous world, brimming with distractions and the relentless tug for our attention, genuine communication becomes a treasure. Active listening emerges as potent and paradoxically under-recognized among the myriad communication tools.

This isn’t merely the passive receipt of words; it’s an immersion into deep engagement, empathy, and connection. At the heart of active listening is a profound recognition of words’ essence, context, and the emotions they channel. Such listening demands our full presence, sidelining any preconceptions or hurried responses.

We build trust and rapport when we actively listen, laying the foundations for more profound interactions. This form of attentive listening illuminates nuances and subtle cues, fostering an enriched understanding. It significantly reduces miscommunication, nurtures empathy, and promotes open dialogue.

Furthermore, with a more rounded grasp of various perspectives, active listeners can make better-informed decisions and absorb information deeply, enhancing learning. At its deepest level, active listening is both a skill and a gift—a profound acknowledgment that the speaker’s thoughts and feelings are valued and understood.

As it becomes increasingly challenging to focus on in our digitized age, the cultivation of active listening is a testament to the significance of true human connection. Through this art, we hear and truly connect, reminding ourselves and others of the irreplaceable power of being genuinely present.

18. Continuous Learning: Embracing the Infinite Potential of Knowledge

At the heart of human evolution lies an insatiable hunger for knowledge. This isn’t just about formal education or acquiring skills for professional pursuits; it’s about the unending journey of personal and intellectual growth. Continuous learning embodies this journey. It’s not a phase or a stage but a lifestyle choice championed by those who realize that the realms of knowledge are limitless.

The continuous learner emerges as an adaptive powerhouse in today’s rapidly evolving world, with its surging technological innovations and shifting paradigms. Such individuals aren’t merely reacting to change; they’re anticipating it, armed with fresh insights, diverse skills, and a mindset anchored in curiosity. This approach transcends professional excellence. It’s about personal fulfillment, where every new knowledge adds depth to one’s worldview, fuels creativity, and nurtures resilience. The continuous learner understands that every day offers lessons, every person they meet can be a teacher, and every challenge, while daunting, carries the seeds of growth.

Moreover, as they delve into diverse fields and platforms, they build networks, fostering professionally enriching and personally rewarding connections. The essence of continuous learning is understanding that our quest for knowledge is a journey without a final destination. In embracing this, individuals don’t just keep pace with the world; they often lead the way, charting paths into yet undiscovered territories of potential and understanding.

In Conclusion: The Symphony of the Mind

Each attribute explored in this series—humility, holistic thinking, active listening, or continuous learning—serves as a distinct note in the vast symphony of critical thinking and personal growth. Individually, they are powerful; collectively, they are transformative. In a constantly evolving world, where challenges morph, and opportunities arise in unexpected quarters, these traits empower us to navigate with clarity, empathy, and foresight.

But beyond the practical benefits, there lies a deeper truth. Our pursuit of knowledge, understanding, and growth is a testament to the indomitable human spirit. It affirms our innate curiosity, resilience, and insatiable desire to make a meaningful mark on the world.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.

Sanju Pradeepa

Have you ever had a problem that was too big to solve right away? Or perhaps you just couldn’t figure out how to approach it? Whether it’s a personal, academic, or professional problem, having the right set of critical thinking skills can help.

Critical thinking is all about carefully evaluating data and making rational decisions. In other words, it’s the skill of analyzing information from many different points of view before drawing a conclusion. It’s an ongoing process that involves gathering information, asking questions, and considering various solutions.

In this guide, we’ll go over different types of critical thinking skills and provide examples of how to apply these skills when approaching a problem from any angle. We’ll also look at ways to sharpen your critical thinking skills so you can tackle any challenge with ease. So let’s get started.

Table of Contents

What is “critical thinking”.

Critical thinking is the ability to analyze a problem or situation and come up with a rational, informed solution. It’s an essential skill for all kinds of processes, from problem solving to decision-making to creative thinking.

In order to tackle complex problems, you need to be able to think critically and evaluate the information at your disposal in order to come up with the best solution.

Critical thinking involves breaking down a problem into its component parts and analyzing it systematically to determine how best to proceed. It requires the ability to think objectively and make informed judgments based on facts and evidence rather than just guesswork or opinion. It also involves the use of several different types of critical thinking skills, such as:

• Analytical Thinking : This type of critical thinking skill involves analyzing data or information in order to draw logical conclusions or find solutions. It’s important for problem-solving and decision-making since it helps you find solutions through careful analysis.
• Creative Thinking: This type of critical thinking skill requires imagination and open-mindedness in order to come up with innovative ideas and solutions. It can help you identify new ways of looking at a situation or find different solutions to a problem.
• Problem-Solving Thinking : This type of critical thinking skill involves developing strategies in order to solve problems quickly and effectively.

Different Types of Critical Thinking

Critical thinking involves analyzing and evaluating information in order to come to a conclusion or make decisions. But did you know that there are different types of critical thinking?

Let’s break down those types of critical thinking skills into 7 different titles and learn them one by one:

1. Analytical Thinking

It is all about taking the pieces of a problem, digging into them, and methodically finding a solution. Analytical thinking is a key element in working through problems and coming up with the best plan of action for success.

So, what does analytical thinking involve? It involves being able to break a problem down into smaller bits and pieces, understanding how each piece interconnects, and developing strategies for solving each individual piece by gathering information relating to it.

Analyzing how each piece of the puzzle affects the next requires you to really understand how they connect together, and using this approach can help you come up with better solutions that can help improve the overall situation.

You’ll also need to make sure any strategies or solutions you come up with are grounded in evidence-based research so that your conclusions are reliable.

Here are some key skills necessary for effective analytical thinking:

• Evaluating: being able to review facts and make judgments about them depending on the situation at hand
• Investigating means asking questions about various aspects of a problem and doing research so that you can identify its root causes.
• Synthesizing: Combining different pieces of data or information together to create new solutions or approaches to existing problems
• Reasoning logically means connecting bits of data together in order to evaluate different possibilities that could help solve the problem or issue at hand.

With these analytical thinking skills, you can start breaking down any problem into smaller, manageable parts, think logically through how they connect together, assess what evidence is needed to make decisions, and draw conclusions based on facts rather than just opinions or hunches.

2. Creative Thinking and Idea Generation

Do you ever feel like your thoughts are stuck in a rut ? Creative thinking and idea generation can help you come up with fresh solutions to problems and break out of that rut.

Creative thinking is an essential critical thinking tool. It can help you look at an issue from a different point of view or think of new ways to approach the problem. Here are some tips for giving your creative thinking skills an extra boost:

• Challenge assumptions.    Even if something seems obvious, take some time to question it and consider other possibilities.
• Brainstorm different solutions . Try writing down potential solutions, no matter how wild they may seem, then look for patterns between them or ideas that can be combined into something new.
• Consider different perspectives. Even if the issue seems cut and dry from one perspective, try to imagine it from other angles and think about how the issue appears from those views.
• Take a break and come back later with fresh eyes: sometimes taking a step away from the problem is enough to give you the necessary distance to discover new ideas or paths of exploration.

These strategies will help dramatically improve your ability to generate new ideas and jumpstart your creative thinking process whenever you need it.

3. Decision-Making

When it comes to critical thinking, decision-making is an essential skill. It’s not just about being able to evaluate a situation; it’s about being able to make a well-informed decision that will bring the best results.

Here are four key components of decision-making:

• Goal Setting : Take time to first identify what you want to accomplish with your decision.
• Analyzing Alternatives: Evaluate the pros and cons of potential solutions before choosing one.
• Risk assessment: estimate the possible risks associated with each potential solution, based on current evidence.
• Implementation: Once the decision is made, start working on implementation tasks and track results for ongoing improvement or refinement.

By following these steps, you’ll be in a better position to make decisions that have positive outcomes for you and those involved in the decision-making process.

The ability to think critically and make sound decisions can not only help you solve problems quickly but can also lead to more successful long-term strategies for your business or organization.

4. Problem-Solving

It is one of the most essential types of critical thinking skills. Problem-solving involves taking all the pieces of a problem and figuring out how to resolve it. This can involve coming up with new solutions, making decisions, devising strategies, and identifying patterns and trends.

It’s an invaluable skill in many aspects of life and can help you create effective solutions to a wide range of problems. To use your problem-solving skills effectively, keep these tips in mind:

• Break the problem down into smaller, manageable parts . Breaking down a problem into smaller chunks makes it easier to work on and understand.
• Look for connections between pieces. Try to identify any connections between different aspects or pieces of the problem to gain insights that may help you solve it more efficiently.
• Don’t get overwhelmed by the scope of the challenge at hand; take it one step at a time and remember that even small victories can help move you closer to finding a solution.
• Think creatively when coming up with possible solutions or strategies; often the best solution is not obvious at first glance.
• Keep track of what works and what doesn’t ; this will give you valuable insights for future problem-solving endeavors as well as feedback on your progress towards resolving the current one at hand.

5. Reflection and Assessing Evidence

Now it’s time to take a look at your own cognitive activity. Reflection and assessing evidence are two types of critical thinking skills that help you make sure you’re not jumping to conclusions without considering the pros and cons of a situation.

When it comes to reflection, this involves being honest with yourself and taking a deep look at the way your thoughts, feelings, and beliefs are informing your decisions. At its core, reflection allows you to objectively evaluate the evidence that’s in front of you so that you can make an informed assessment about what the best next step is for a given problem or situation.

Assessing evidence is also critical for coming up with effective solutions. This means carefully examining the available data and making sure you have all of the necessary information before reaching an opinion or making a decision. It involves looking at multiple perspectives and interpretations of any given issue so that you can form an educated conclusion about how best to solve it.

6. Open-mindedness

It is a critical thinking skill that is all about trying to understand something from different perspectives and being able to appreciate the difference in opinions. Open-mindedness allows you to analyze a problem from multiple angles and consider different solutions or ways of approaching it.

Here are some tips for developing open-mindedness as a critical thinking skill:

• Listen carefully and actively to others ; rather than just hearing words, try to understand their point of view.
• Ask questions without judgmen t and without assuming your own opinion is the right one.
• Pay attention to how other people view the same situation differently than you do.
• Think critically and evaluate arguments objectively, without assumptions or preconceived ideas about what the answer should be or which course of action should be taken.
• Suspend judgment until you have enough information about a topic or situation; don’t jump to conclusions too quickly.
• Prioritize respect when engaging with others who have different perspectives. Be willing to put in the effort required to understand why they think that way and why that might be important to them in their lives or work.
• Avoid making assumptions about what someone else believes; find out more first before passing judgment on someone’s opinion or actions.

By developing this type of open-mindedness, you can become more aware of how your personal biases may impact your ability to think critically, improving your overall decision-making skills over time and helping you become a more valuable asset as part of any team or organization.

7. Good communication

Good communication is an important part of the critical thinking process. That’s because having good communication skills helps you be more persuasive, helping you convince people of ideas and solutions that are well thought-out. It also allows you to better explain and justify your reasoning to others, which is essential when looking at complex problems.

To have strong communication skills, it’s important to think before you speak. You should also take the time to clearly articulate your thoughts, using simple yet powerful language. Additionally, having an open mind is key. It allows you to consider different angles and perspectives on any issue or problem that you might face.

Here are some tips for good communication:

• Take a moment to succinctly formulate your thoughts before speaking or writing them down.
• Ask questions when necessary, and listen carefully to what others have to say.
• Stay open-minded in conversations, as this will help broaden your knowledge of the situation.
• Speak clearly and use accurate language so that your message won’t be misunderstood.

While it’s true that critical thinking skills can’t be taught in just a few days, plenty of work and practice can go a long way toward equipping you to think critically about the problems in your life. With the right practice and guidance, you can become a master at analyzing issues, discerning cause and effect, and integrating facts to formulate your strategy.

If you’re looking to hone your critical thinking skills, start by breaking down a problem into its component parts. Assess the evidence, identify assumptions, and determine the best course of action. With practice and dedication, you can develop the analytical skills to resolve complex problems and make better decisions in the future.

 The widespread developments of the twenty-first century have been accompanied by the presentation of intellectual patterns and theories and new achievements. These new achievements emphasize the skill of thinking at high levels, especially in the educational system of universities. This skill is essential for medical students; therefore, the present study aimed to investigate the qualitative barriers of critical thinking in medical students' curriculum.

 This is a qualitative study in which the content analysis method has been used. Participants of this study included 11 medical education experts and medical students (6 females and 5 males) who were selected through a semi-structured interview and purposeful sampling. The data analysis method was conventional content analysis. In the next part, by more investigation of the data, various obtained concepts will be presented in the form of themes, categories, and subcategories.

We obtained two themes (socio-cultural conditions and traditional and unchanging system of education), eight categories and 14 subcategories. Also, these categories were resistance to critical society, intellectual tension, personality characteristics, lack of understanding of society's need for criticism, the rule of traditional teaching pattern, lack of critical thinking skills, ineffective evaluation, and difficulty of critical thinking training.

Conclusion:

 Given the results and the main emphasis of curriculum planners on incorporating high-level critical thinking and revision skills into the curriculum, the country's academic education system requires a change in the thinking style, research, deepening critical thinking, and a change in teachers' attitudes toward curriculum designing (goals, content, teaching and evaluation methods); also, it is suggested that the authorities should pay attention to the need to develop and utilize critical thinking skills in the learners’ education.

Introduction

The widespread and vast developments of the 21st century are accompanied by the presentation of intellectual patterns and theories and the production of modern science and technology. One of the new achievements of this century is emphasis on thinking methods, especially in the educational system ( 1 ).

Critical education is a relatively modern theory developed by educators such as Paulo Freiere, Henry Giroux, Peter McLaren, Michael Apple, and Douglass Kellner based on the principles of critical theory ( 2 ). In this type of education, wisdom, critique, and interpretation are considered as valuable educational goals. The primary approach of this tutorial is, as mentioned before, toward critical thinking. In this type of training, the use of memory and old knowledge is diminished, and learners can analyze, evaluate, and interpret the material. Accordingly, the training of the criticizer and wise students is the first goal of university education to confront the changing society in this age of multiple information explosion ( 3 ).

Critical thinking is a type of high-level thinking skills used by students, i.e. they use personal perspectives and approaches rather than simple acceptance without evaluating the others' judgments, attitudes, and information ( 4 ). The central core of critical thinking is cognitive skills such as interpretation, analysis, evaluation, inference, explanation, and self-regulation.

Critical thinking in the field of medical sciences is a kind of cognitive activity for understanding and evaluating the phenomena based on reasoning and analysing ( 5 - 6 ). Having a critical thinking skill for a physician helps him make the right clinical decision and provide the best care in the patient care process ( 7 - 8 ). The ability to solve a problem at the patient's bedside is valuable in the health process.

Designing the curricula can reflect the important belief in medical students that they should learn these experiences not only to maximize their potential, but also use it as a general skill in classrooms, and conduct this vital issue to the other areas, their other life aspects, and future career ( 9 , 10 ). With this in mind, the importance of the students' curriculum in fostering the students' critical thinking becomes apparent.

Therefore, the institution of education in academic education must carry out its mission to review the goals, content and educational materials, methods of teaching-learning, and the evaluation system and everything related to the curriculum. It should be noticed that the surface change will not be responsive to the revision of the curriculum and that fundamental and logical changes in all curriculum processes are essential ( 11 , 12 ).

The university education course is one of the most critical training courses in every person's life. As the period of school education transition, and objective thinking is the entry into the abstract and adolescent thinking that comes with entering the job market and assuming significant responsibilities in life ( 5 ). It should be stated that people studying critical thinking skills at the university are always looking for reasons and evaluating them in real life and resisting misleading prejudices ( 13 ). Therefore, if students engage in critical thinking skills and critical thinking values are developed in them, social benefits will have to be obtained that will be so huge ( 14 - 15 ).

Amini and Fazli Nejad (2000) reviewed the critical thinking skills of the students of the general practitioners of the medical school of Shiraz University of Medical Sciences; the results of this study showed that students were weak in using critical thinking skills ( 16 ).

Mc Grace's study (2003) showed that the mean scores of critical thinking skills of medical students are increasing from year 1 to 4 (except the third year) ( 17 ). The results of Paul's (2014) Delphi study showed that the curriculum should be designed in such a way as to enhance critical thinking and make it possible to evaluate it. Sufficient time needs to be allocated to assess critical thinking ( 18 ).

Agnesno and Marie (2005) in a study criticized barriers to critical thinking, such as lack of faculty knowledge, use of teaching and assessment methods that do not facilitate the critical thinking of the learners, negative attitudes of faculty members towards change and their resistance to change, inappropriate selection process and poor educational backgrounds that do not facilitate the students' critical thinking, insufficient socialization, culture, and inadequacies of education ( 19 ).

Recently, given the dramatic changes in the students' curriculum, especially the volume of courses and the need to integrate medical courses, the attention of the academic education system to curriculum revisions has been criticized. On the other hand, given the integrated complexity of critical thinking, the importance of revising the curriculum becomes more critical. Therefore, the present study aimed to investigate the barriers of critical thinking in the medical school curriculum from the viewpoints of medical education experts. Perhaps, the qualitative recognition of these barriers in the curriculum has made it possible to redefine it to develop critical thinking in medical students and its importance in their future lives and careers.

This is a qualitative study aiming to explain the barriers of critical thinking in the medical school curriculum. In this study, using the qualitative research approach, critical thinking barriers in the medical school curriculum were explained from the viewpoint of medical education experts of Shiraz University of Medical Sciences. In this section, semi-structured interviews were used to collect the data.

The research context was affiliated to Shiraz University of Medical Sciences, School of Medicine, and clinical and basic sciences groups. These environments provided access to qualified teachers. In this study, participants were selected from the Faculty of Medicine in the departments of Basic and Clinical Sciences, and faculty members of the Department of Medical Education and five medical students were selected by purposive sampling method. The sampling was continued until the previous information was repeated, and the content or new nature of the participants were not extracted.

Inclusion criteria were the participants’willingness to participate in the study and express their views, opinions and wealth of information, and teachers with more than five years of teaching experience in the university regarding the concept under the study. 

Before collecting the data, the researcher provided explanations about the goals, process and conditions of the interview. The data were then extracted using semi-structured interviews with open non-led questions and collected using a few guide questions. The interviews were started with general questions such as “What do you mean by critical thinking?”, “Have you experienced critical thinking in the curriculum?” and "How did you incorporate critical thinking into the curriculum?", Or "What are facilitators or inhibitors of critical thinking in medical students' curriculum? Explain it. Interviews continued based on the responses of contributors and with the help of exploratory questions, such as "Explain more. What is your example?, or What do you mean? ". Subsequent questions were based on initial responses of individuals or analysis of previous interviews. The duration of each interview was about 30 to 45 minutes, considering the faculty members' time. Interviews continued until data saturation, and sufficient information was received. After the participants' agreement interview was done in a relaxed and comfortable environment. All interviews were digitally recorded and verbatim word by word. Data analysis was carried out simultaneously with data collection. The simultaneous analysis of the interviews provided the main people with access to further interviews, resulting in more valuable information.

In the present study, to analyze the data obtained from interviews, we used a qualitative content analysis approach in the conventional way ( 20 ). The analytical unit was firstly determined by rewriting the interviews right after each section. Data analysis began by repeated reading of interviews, so that the researcher obtained an overview of the concept. Subsequently, based on the descriptions of the participants, semantic units containing meaningful sentences and words were identified and analyzed. In this way, the order of raw codes was extracted based on the nature of the data.

Continuously, the process of reduction and compression of semantic units was done. Thus, each semantic unit was named and conceptualized in terms of its implications. Then, the same necessary codes were merged and organized and categorized into the first classes.

We tried to group the codes that are more similar to each other in the same categories. In other words, the codes categorized within the classes were homogeneous and heterogeneous with other classes. Then, the primary classes were merged based on the relationship between them, and the main classes were formed. In the final stage, the researcher tried to discover the central themes by comparing and revisiting the classes and subclasses. At this stage, by integrating the same main classes, the content of the barriers to critical thinking was derived from the curriculum of medical students.

Strobert and Carpenter (2011) have proposed four criteria of validity or reliability, transferability, and verifiability for evaluating and validating data in qualitative research that have been used in this research ( 21 ).

Trustworthiness

In the end, the extracted themes were presented to the participants (member check) and it was found that some changes were needed. The themes were also provided by one of the qualified qualitative experts who tried to present all the opinions of the experts in conveying the concepts to the audience (peer check).

In this part of the study, the findings of the research are presented in order to explain and identify the barriers of critical thinking in the medical school curriculum by content analysis method. In general, the analysis of the interviews in this study was that during the data comparison process, 47 codes were initially extracted from the interviews, which were subdivided into nine main categories after data analysis and integration. Finally, from the clean codes, 14 subcategories, 8 main classes, 2 themes (socio-cultural conditions and traditional and unchanging system of education) were formed. Table 1 shows the themes, categories, and subcategories.

Subjects, main categories, and subcategories extracted from the study

A) Socio-cultural conditions

Providing the right educational and cultural conditions that separate the individual from school education and provide rapid and widespread access to the community and labor market in a college education course is useful in fostering a critical personality. . Given the importance of this topic, social-cultural conditions were the first themes extracted from the qualitative data analysis in this study. The theme consists of three main categories: "resistance to critical society," "tension," and personality factors, which are described below in each of the main categories and subcategories of this theme.

1. Resistance to the critical community: Based on the experiences of the study participants, resistance to society and belief in the superiority of collective thinking over independent thinking as the first significant category were the two subcategories of "linear thinking-intellectual dogmatism" and "systemic obedience."

1-1. The Linear Thinking-Intellectual Dogmatism

Based on the concept of this subcategory, the participants in this study acknowledged that in the current situation, some linear thinking prevails, according to which, without sufficient knowledge of the community's need for criticism, medical schools only train students in a parrot-like and linear fashion.

One contributor commented on positive support for critical thinking:

"When we train the learner with traditional methods, like lectures, and do not use collaborative educational methods and class discussions, the focus and accuracy will be reduced, and the quality of education will also be affected."  (Professor-Contributor No. 8).

The same participant said:

"... there are many students, and it is not easy to control them in the collaborative space and the discussion in the class; on the other hand, the increase in the volume of the course contents and the need to teach all the concepts in the classroom does not provide the opportunity for participatory teaching; therefore, there is not enough opportunity to interact or educate. "  (Professor-Contributor No. 8).

An increase in the volume of the course content, a large amount of documentation in the curriculum, unbalanced workload, and the need to maintain the conditions and get used to implementing traditional training in the classroom are the items participants referred to in expressing their experiences in examining the causes of linear thinking.

1.2. Obedience in the system

Submissiveness in the system is the second main category, and this means that obedient thinking is the product of linear thinking. Contributors mentioned the critical role of obedience, stereotyping, and non-positive mental flexibility in the learning system of learners. One of the participants said:

"The current educational system of the university directs the learner to follow a routine and uniform process and expects them to take a clear and coherent framework. In this atmosphere, the student moves toward a kind of stereotype and cliché. " (Participant No. 3).

One of the contributors believed in the students' desire for traditional education and use of simple mental stereotypes rather than using specific solutions and says:

"Students are interested in temporary and common solutions because of their past education during school time; they are reluctant to participate in class discussions and find creative solutions to the problems."  (Professor- Contributor No. 4).

Another participant believed that:

"Given that the professor has provided space for collaborative learning, in most cases, mental prejudice and lack of critical thinking of learners into specific ideologies and beliefs and mental stereotypes on a particular issue prevent the use of critical thinking skills and the emergence of creative solutions in the classroom." (Professor- Participant No. 12).

2. Intellectual tension

Intellectual stress is the second major category of socio-cultural conditions based on the participants' experiences, consisting of three subcategories of "anxiety, stress and fatigue," "curriculum overload," and "mental messiness." 

2.1. Anxiety, stress, and fatigue

Anxiety, stress, and fatigue were one of the aspects of distracting factors that triggered specific social conditions and factors such as war and sanctions, and ultimately prevented critical focus and thinking on the issues.

One of the participants stated his experiences on stress and exhaustion of learners in the educational environment:

"Sometimes in the classroom I find that some students do not have enough focus on lessons because of fatigue, and sometimes they take a nap in the classroom; stress makes them sick, perhaps due to the educational method, which has taken the opportunity of students to participate and think. "  (Professor- Participant No. 1).

2.2. Curriculum Overload

Providing enough space and time to think about the subject and participate in different topics that were experienced by most of the participants can be useful in enhancing critical thinking skills.

In this regard, one of the participants believed that:

"Due to the compactness of the curriculum of the basic sciences of students, there is no opportunity to present the concepts collaboratively, and they must quickly teach the subject, which removes the atmosphere of thinking and discussing from students." (Student- Participant No. 3).

Also, another participant believed that:

"A large amount of course content in the basic sciences causes the dispersion and confusion of students and takes the opportunity to discuss and think about different concepts from the students."  (Student- Participant No. 6).

2.3. Not-Organized Thinking

Most students expressed distraction, slackness, and lack of mental focus on various subject areas in their experiences, which reduced or neglected the use of critical thinking skills.

"Some participants at the time of entering the university do not have any specific plans of their future, and they are also confused, unobtrusive, and wacky in the classroom, and they usually go from branch to branch."  (Professor-Participant No. 5).

The other participant noted that:

"The confusion and distraction of learners during the education period and the lack of focus on the concepts of learning may prevent the acquisition of new information."  (Student-Participant No. 14).

Another participant in her experience stated that:

"Many entrance exam counselors advise the learners to endure the hardships of studying for a course that will make them more comfortable and free after passing the exam, which will confuse the learners."  (Student-Participant No. 15).

 Most learners in high-level mental situations often think of routines and familiar affairs, which is caused by the entrance exam thoughts leading to lack of attention to innovative and new options. This is due to brain dispersion ?? and slackness and, on the other hand, to thinking in a particular mental context that prevents a person from thinking and creative solutions.

3. Personality characteristics

Faculty members believe that increasing self-confidence is one of the essential needs of all people, especially students. We usually get the most out of those who have high self-esteem because these people have characteristics which make loving people and are often more admired. These people cause classroom dynamics, challenge different issues and opinions, and support their ideas in various topics and provide them with acceptable collective arguments. The existence of such learners is necessary for every educational environment. This theme consists of three categories: "lack of self-esteem," "lack of motivation," and "lack of curiosity in the search for information."

3.1. Lack of confidence

Based on the experiences of the participants, one of the characteristics of the learner's personality that is effective in strengthening critical thinking is self-confidence.

One of the participants believed that:

"Learners who have higher levels of self-esteem in the learning environment and lessons of discussion use critical thinking in decision making and solving different issues, and do not retreat from class positions in class discussions and debates. They have various reasons for their answers, which make a significant contribution to classroom dynamics. " (Student-Participant No. 12).

In this regard, one other participant also said:

"One of the significant barriers to developing critical thinking is the very nature of personal thinking processes. Individuals with high self-esteem seek information and exchange their thoughts in the classroom, and this results in classroom dynamics and better education and higher quality for all learners. " (Professor-Participant No. 4).

The findings suggest that learners with high self-esteem are more successful than their classmates. In other words, learners with a higher level of self-esteem have a better job and a better position than the others and achieve more success in society. This is why increasing self-esteem is one of the essential steps in the success of critical thinking in learners.

3.2. Lack of motivation

Participants' experiences confirm that lack of risk-taking, low self-esteem, and lack of motivation to risk are the primary barriers to critical thinking in learners.

One of the participants stated that:

"Teaching critical thinking is useless to learners who do not have the incentive to use critical thinking in the classroom." (Professor-Participant No. 3).

The participant adds that:

"Learners in the classroom have to work together with faculty members and other learners to analyze issues and topics and find the right solutions actively. To achieve this educational success, the learners should have sufficient motivation as a prerequisite. This motivation can be enhanced with various rewards such as class support and encouragement and feedback, and even so, to say, it can motivate learners to become more risk-averse. " (Professor-Participant No. 4)

3.3. Curiosity in search of information

Participants have experienced that curiosity is the key to developing learning intelligence, and it is a personality trait of some people. Having this feature strengthens critical thinking skills in classroom debates and topics.

“The faculty members must allocate more time for negotiation and show critical thinking while they are teaching. They should also use methods to raise the students’ curiosity.” (Professor- Participant No. 9).

Having some personality traits such as self-confidence, curiosity, flexibility, and creativity, willingness to think is useful in developing critical thinking.

B) The traditional and unchanging system of education

According to the participants and their experiences, the traditional and unchanging system is hard to change, and it doesn't accept any innovation. Believing in this method of passive teaching and learning is a common practice in many academic educational settings. In recent years, considering the positive effects of modern teaching and their acceptance in academic settings, the use of modern teaching methods has been considered that can provide a space for the use of critical thinking skills. The five main categories included "lack of understanding of the community needs for criticism," "dominance of the traditional teaching model," "lack of experts in critical thinking," "ineffective evaluation," and "the difficulty of critical thinking education."

1. Lack of understanding of social needs for criticism

Based on the experiences of the participants, the role of criticism in the curriculum is unclear, and the need for criticism seems urgent. In this regard, fostering critical thinking and developing an appropriate curriculum by incorporating critical thinking concepts and skills can be very useful.

One participant believed that:

"The current curriculum concepts are usually incompatible with the needs of learners and today's society, and the need to rethink curricula is very much felt, while students need to educate themselves on critical thinking and not just accumulate much content in their minds."  (Student- Participant No. 14).

Another participant adds that:

"Teaching students to use critical thinking skills helps them to solve real-life issues and situations in their community and their career prospects, which should be specifically addressed in the curriculum."  (Professor- Participant No. 9).

"Curriculum design is fundamental considering the space for research, hypothesis and idea development in different topics and appropriate timing for learners to utilize critical skills, and it will also have an impact on the future of students' careers and community needs. " (Professor- Participant No. 2).

Critical thinking can be improved through needs assessment and curriculum development which includes essential components such as goals, content, teaching, and evaluation process to foster the learners' critical thinking to achieve creativity and academic achievement.

2. The Rule of Traditional Teaching Pattern

New ways of planning and integrating student courses based on the participants' experiences have been considered. The use of these new teaching methods provides the appropriate space for practicing and critical thinking skills in learners. However, in practice, traditional teaching patterns usually preclude the comprehensive and complete implementation of new teaching methods.

"Most teachers are interested in using traditional teaching methods, and learners have become accustomed to these methods, and they are more than happy to be provided with written content and only memorize the content. " (Professor- Participant No. 10).

Another participant added that:

"Students usually fail to think multidimensional in a variety of subjects around the classroom, and they usually continue one-dimensionally and just memorize the lesson content and avoid participating in different topics or thinking about different subjects."  (Student- Participant No. 16).

This section notes that the use of new teaching methods can provide a space for the use of critical thinking skills.

3. Lack of critical thinking skills

Participants in their experiences stated that faculty members did not have sufficient mastery of critical thinking concepts at present. The use of highly qualified teachers in modern teaching methods and the provision of a suitable environment for student learning has made critical and questioning skills essential in the current teaching environment.

One participant added that:

"Young teachers are usually interested in new teaching methods in their teaching and provide a space for discussion, suggestions, and criticism of free and independent concepts and thinking, which is usually reduced by the work experience of the faculty members, as well as their lack of time. " (Professor- Participant No. 6).

"Some subjects are not considered by the teachers because they cannot be taught in traditional teaching methods. These topics will only be transferable to collaborative discussions or classroom discussions with learners."  (Professor- Participant No. 5).

4. Ineffective evaluation

The experiences of the participants in this study confirm that evaluation without feedback and taxonomy of critical thinking is ineffective in evaluating the learners, and providing feedback in this space is one of the most difficult challenges to which the teachers are faced. On the one hand, the provided feedback must be truthful. On the other hand, feedback should be given to learners at the right time in order to be active and efficient. Providing students with the right feedback at the right time can be one of the appropriate methods of evaluation that enhances their critical thinking skills.

One participant in providing feedback to the students mentioned that:

"Despite the fact that students enjoy receiving rewards or correcting their bugs during their teaching, university faculty members, due to their busy work and high volume of teaching materials, avoid providing a collaborative learning environment with questions and answers while teaching and appropriate evaluation and feedback and they usually finish the teaching with traditional teaching methods, which can affect the quality of teaching. " (Professor- Participant No. 11).

Good feedback always comes with positive things that help the learners feel more at ease and take more steps to succeed, advance and ask questions that require excellent thinking skills to be answered.

5. The difficulty of teaching critical thinking

Providing students with critical thinking skills in educational settings is very difficult, making it less likely to use this teaching method in the classroom.

One contributor believed that:

"Due to the size of the curriculum and the need to train all the resources, teaching traditionally seems more appropriate because taking classes in a new way of teaching will waste the time and not transfer all the subjects to the students."  (Participant No. 6).

"Holding the classroom in new ways is time-consuming and difficult, and the trainees usually do not make effective use of the available space, so the teaching time is spent on unnecessary discussions instead of transferring lesson concepts that will not do better for students than wasting class time."  (Participant No. 7).

It is necessary to develop critical thinking for a learner, due to the increased amount of information, judgment and decision making, and the improvement of the individual and professional life, ( 22 ). Analyzing the data showed that the two themes of cultural-social conditions and the unchanging traditional system are the main barriers of critical thinking in the medical school curriculum.

Cultural-social conditions constituted the first key infrastructure of critical thinking barriers for medical students. The findings of the present study showed that lack of support for independent and critical thinking was one of the most critical issues that most participants mentioned. Rezaei and Haqqani (2015) have studied the causes of resistance to change; they considered the lack of participation of learners in classroom education and values and the shortage of support for creative thinking as one of the most important reasons for resisting changes. What is more, he believes that in order to implement the change successfully, we need to find appropriate solutions to overcome these causes ( 23 ). The results of this study are consistent with those of the present research.

On the other hand, submissiveness in the system is another aspect of this dimension, which is incompatible with the results of the research by Graham (1991) ( 24 ). He has concluded that older people, especially if they are single, look at obedience superficially, and try to solve the issues more creatively and discuss different issues more critically. This result is also consistent with those of the Kalantari and Babayan’s (2014) study ( 25 ).

According to the findings of this study, distortion factors are one of the other themes of this research. Anxiety, stress, and fatigue were the most important aspects of this research. Najafian Zadeh et al. (2014) have concluded that the critical thinking of the students in our country is weak, and one of the causative factors was anxiety and fatigue in students, which was due to the high volume of the courses ( 26 ). Since critical thinking is not considered as an essential dimension in the teaching of students during the educational process by the educational system, and critical thinking is a complex mental process that provides flexibility, proper response, correct predictions and rational decision making of the students in different situations, it is necessary to pay attention to this issue by improving educational patterns, which is consistent with the results of this study.

The lack of enough time to think was another obstacle to this dimension. In this regard, Sharifi et al. (2016) concluded that the use of the assistants of critical thinking capabilities was weak, and this was because they are so busy and do not have enough time during the study that is in the same line with the results of this study ( 27 ).

Intellectual stress is the last theme of this study, the most important aspects of which were anxiety, stress and fatigue, an overload of curriculum, and intellectual fatigue. 

In the research by Durova et al., ( 28 ) participation learning was also a method of developing critical thinking; also, discussing and revealing new ideas and evaluating other people's ideas for developing critical thinking and problem-solving skills and participatory learning were usd. By creating learning management and meaningful experiences and stimulating the learners to think, faculty members have a facilitating role in this issue.

The last subject of this research was the personality factors that included issues such as lack of self-esteem, lack of motivation, and curiosity in seeking information that was attractive to the participants. In this regard, the results showed that, in the viewpoint of the experts participating in this study, one of the most effective barriers to the use of critical thinking is personality barriers. The investigation of numerous texts has shown that having some personality traits such as self-esteem, curiosity, flexibility, creativity, and willingness to think is valid in critical thinking skills ( 13 ). Therefore, the absence of any of these personality traits in individuals can be a barrier to critical thinking. Some scholars believe that critical thinking embraces something beyond the aspects of intelligence and individual performance, and other factors such as emotional and personality traits also affect it ( 14 ). As a result, it seems that before entering the clinical field, it is necessary to go through psychological courses to improve individual characteristics and, thus, increase the skill in critical thinking because the goal of teaching critical thinking is to educate people who are far from personal prejudice and who are careful about their work ( 13 ).

In the personality aspect of the students, "lack of self-esteem" was considered by the experts participating in this study to be the most crucial factor in not using critical thinking, which could cause passive confrontation with events and referral to the authorities. Therefore, along with nursing lessons and in-service training, it is necessary to use strategies for increasing the self-esteem of the nurses and students.

The second theme of this study was the traditional and unchanging system of education which consisted of five categories: "lack of understanding of the need for critical society," "rule of traditional teaching," "lack of experties in critical thinking," "ineffective evaluation" and "difficulty in teaching critical thinking." As noted, the lack of understanding of the community's needs for criticism was one of the main categories of the subject, and it addressed issues such as the lack of attention of curriculum planners to critical thinking and high-level skills in the curriculum. In this regard, researches have been done to confirm the impact of goals on the content, teaching methods, and evaluation as curriculum elements in fostering critical thinking. Based on Vagra’s research (2007) in Lipton School, which teaches in-service teachers, consideration of structure, theory process, this is an essential indicator that critical thinking skills can be achieved through the selection of goals, content, and processes and methods ( 29 ).

Another aspect of this theme was the ineffectiveness of the traditional model of teaching and evaluation. In other words, enhancing motivation to use thinking as the key to improving the quality of students' critical thinking is typically overlooked in the formal curriculum of students; therefore, one of the most effective measures in this regard is to improve the attitude aspects of critical thinking, considering the hidden curriculum function in higher education. In this regard, the researches by Alipour ( 2 ), Sharifi ( 26 ), and Shariatmadari ( 30 ), have neglected development of questioning, analysis, composition and evaluation skills and judgment in learner curriculum, and the lack of attention to the hidden curriculum has been considered one of the significant barriers to developing critical thinking skills. Research by Talebzadeh et al. (2009) has also considered attention to hidden curriculum elements as one of the influential factors in fostering critical thinking ( 29 - 31 ).

Lack of experts in critical thinking was one of the other main categories of this theme. In this regard, Cook and Mull's research points to learning-based approaches to promoting critical thinking, problem-solving, active participation, identification of learning needs, creative discussion, peer learning, and the integration and production of knowledge that make learning realistic, entertaining and attractive.

The difficulty of teaching critical thinking was the last category of this theme; in this regard, research by Drewa et al. found it necessary to discuss and reveal new ideas and evaluate the ideas of others to develop critical thinking and problem-solving skills and collaborative learning, and young teachers have been identified as facilitators or leaders of learning and creators of meaningful experiences that stimulate the learners to think.

According to the results of research done in this dimension, most educational systems tend to have a fixed curriculum content in the curriculum without the use of new, collaborative learning methods in learners, all of which discouraging the students from using critical thinking skills.

Application of findings

The findings of this study provide an overview of the critical thinking situation in the academic environment and the barriers of utilizing critical skills in medical students that can be a practical step in revising and designing curricula with a more comprehensive view of new educational practices, especially concepts and critical thinking skills.

Study limitation

In this study, access to experienced professors in this field was difficult nationwide. However, we sought to use any source of information, scholars, and students in this field.

The educational system Our educational system needs a development which relegates the education from extreme reliance on old knowledge; brings prospects into thinking, intellection, research, creativity, and innovation;blossoms the students’ talents; deepens the critical spirit of critique and review; boosts the self-esteem and self-confidence; and promotes the educational, biological, technical and professional skills in the young generation. Such a change will be possible by changes in the attitudes of the faculty members, planners and curriculum in formulating strategic plans for goals and content, and also teaching and evaluation methods for curricula and attention to the importance and necessity of developing critical thinking at different levels of education. 

In general, the cultural and social conditions of the traditional and unchanging system of education were two significant barriers to the implementation of the critical thinking program, which seems to overcome these barriers to provide critical thinking concepts and skills in medical students' curricula. Therefore, it can be concluded that the reform of the educational system in educational and clinical environments is one of the strategies for increasing the use of critical thinking.

Academic faculty members can help to improve the critical thinking skills of their learners by creating an atmosphere of inquiry and an appropriate platform for negotiation. Establishing workshops and meetings for familiarizing and enhancing search skills, questioning techniques, and evaluating the value and content of information, as well as holding workshops, can reduce the significant barriers to critical thinking development with effective use of information by students. Therefore, based on the results of this study, it is recommended that an effort should be made to transform the classroom environment into the interface between learners and faculty members through the elimination of the existing barriers.
