I reviewed this book for a course titled "Creative and Critical Inquiry into Modern Life." It won't meet all my needs for that course, but I haven't yet found a book that would. I wanted to review this one because it states in the preface that it fits better for a general critical thinking course than for a true logic course. I'm not sure that I'd agree. I have been using Browne and Keeley's "Asking the Right Questions: A Guide to Critical Thinking," and I think that book is a better introduction to critical thinking for non-philosophy majors. However, the latter is not open source so I will figure out how to get by without it in the future. Overall, the book seems comprehensive if the subject is logic. The index is on the short-side, but fine. However, one issue for me is that there are no page numbers on the table of contents, which is pretty annoying if you want to locate particular sections.

Content Accuracy rating: 4

I didn't find any errors. In general the book uses great examples. However, they are very much based in the American context, not for an international student audience. Some effort to broaden the chosen examples would make the book more widely applicable.

Relevance/Longevity rating: 4

I think the book will remain relevant because of the nature of the material that it addresses, however there will be a need to modify the examples in future editions and as the social and political context changes.

Clarity rating: 3

The text is lucid, but I think it would be difficult for introductory-level students who are not philosophy majors. For example, in Browne and Keeley's "Asking the Right Questions: A Guide to Critical Thinking," the sub-headings are very accessible, such as "Experts cannot rescue us, despite what they say" or "wishful thinking: perhaps the biggest single speed bump on the road to critical thinking." By contrast, Van Cleave's "Introduction to Logic and Critical Thinking" has more subheadings like this: "Using your own paraphrases of premises and conclusions to reconstruct arguments in standard form" or "Propositional logic and the four basic truth functional connectives." If students are prepared very well for the subject, it would work fine, but for students who are newly being introduced to critical thinking, it is rather technical.

It seems to be very consistent in terms of its terminology and framework.

Modularity rating: 4

The book is divided into 4 chapters, each having many sub-chapters. In that sense, it is readily divisible and modular. However, as noted above, there are no page numbers on the table of contents, which would make assigning certain parts rather frustrating. Also, I'm not sure why the book is only four chapter and has so many subheadings (for instance 17 in Chapter 2) and a length of 242 pages. Wouldn't it make more sense to break up the book into shorter chapters? I think this would make it easier to read and to assign in specific blocks to students.

Organization/Structure/Flow rating: 4

The organization of the book is fine overall, although I think adding page numbers to the table of contents and breaking it up into more separate chapters would help it to be more easily navigable.

Interface rating: 4

The book is very simply presented. In my opinion it is actually too simple. There are few boxes or diagrams that highlight and explain important points.

The text seems fine grammatically. I didn't notice any errors.

The book is written with an American audience in mind, but I did not notice culturally insensitive or offensive parts.

Overall, this book is not for my course, but I think it could work well in a philosophy course.

This textbook is not particularly comprehensive (4 chapters long), but I view that as a benefit. In fact, I recommend it for use outside of traditional logic classes, but rather interdisciplinary classes that evaluate argument

To the best of my ability, I regard this content as accurate, error-free, and unbiased

The book is broadly relevant and up-to-date, with a few stray temporal references (sydney olympics, particular presidencies). I don't view these time-dated examples as problematic as the logical underpinnings are still there and easily assessed

Clarity rating: 4

My only pushback on clarity is I didn't find the distinction between argument and explanation particularly helpful/useful/easy to follow. However, this experience may have been unique to my class.

To the best of my ability, I regard this content as internally consistent

I found this text quite modular, and was easily able to integrate other texts into my lessons and disregard certain chapters or sub-sections

The book had a logical and consistent structure, but to the extent that there are only 4 chapters, there isn't much scope for alternative approaches here

No problems with the book's interface

The text is grammatically sound

Cultural Relevance rating: 4

Perhaps the text could have been more universal in its approach. While I didn't find the book insensitive per-se, logic can be tricky here because the point is to evaluate meaningful (non-trivial) arguments, but any argument with that sense of gravity can also be traumatic to students (abortion, death penalty, etc)

The text covers all the relevant technical aspects of introductory logic and critical thinking, and covers them well. A separate glossary would be quite helpful to students. However, the terms are clearly and thoroughly explained within the text, and the index is very thorough.

The content is excellent. The text is thorough and accurate with no errors that I could discern. The terminology and exercises cover the material nicely and without bias.

The text should easily stand the test of time. The exercises are excellent and would be very helpful for students to internalize correct critical thinking practices. Because of the logical arrangement of the text and the many sub-sections, additional material should be very easy to add.

The text is extremely clearly and simply written. I anticipate that a diligent student could learn all of the material in the text with little additional instruction. The examples are relevant and easy to follow.

The text did not confuse terms or use inconsistent terminology, which is very important in a logic text. The discipline often uses multiple terms for the same concept, but this text avoids that trap nicely.

The text is fairly easily divisible. Since there are only four chapters, those chapters include large blocks of information. However, the chapters themselves are very well delineated and could be easily broken up so that parts could be left out or covered in a different order from the text.

The flow of the text is excellent. All of the information is handled solidly in an order that allows the student to build on the information previously covered.

The PDF Table of Contents does not include links or page numbers which would be very helpful for navigation. Other than that, the text was very easy to navigate. All the images, charts, and graphs were very clear

I found no grammatical errors in the text.

Cultural Relevance rating: 3

The text including examples and exercises did not seem to be offensive or insensitive in any specific way. However, the examples included references to black and white people, but few others. Also, the text is very American specific with many examples from and for an American audience. More diversity, especially in the examples, would be appropriate and appreciated.

This is an excellent introductory (first-year) Logic and Critical Thinking textbook. The book covers the important elementary information, clearly discussing such things as the purpose and basic structure of an argument; the difference between an argument and an explanation; validity; soundness; and the distinctions between an inductive and a deductive argument in accessible terms in the first chapter. It also does a good job introducing and discussing informal fallacies (Chapter 4). The incorporation of opportunities to evaluate real-world arguments is also very effective. Chapter 2 also covers a number of formal methods of evaluating arguments, such as Venn Diagrams and Propositional logic and the four basic truth functional connectives, but to my mind, it is much more thorough in its treatment of Informal Logic and Critical Thinking skills, than it is of formal logic. I also appreciated that Van Cleave’s book includes exercises with answers and an index, but there is no glossary; which I personally do not find detracts from the book's comprehensiveness.

Overall, Van Cleave's book is error-free and unbiased. The language used is accessible and engaging. There were no glaring inaccuracies that I was able to detect.

Van Cleave's Textbook uses relevant, contemporary content that will stand the test of time, at least for the next few years. Although some examples use certain subjects like former President Obama, it does so in a useful manner that inspires the use of critical thinking skills. There are an abundance of examples that inspire students to look at issues from many different political viewpoints, challenging students to practice evaluating arguments, and identifying fallacies. Many of these exercises encourage students to critique issues, and recognize their own inherent reader-biases and challenge their own beliefs--hallmarks of critical thinking.

As mentioned previously, the author has an accessible style that makes the content relatively easy to read and engaging. He also does a suitable job explaining jargon/technical language that is introduced in the textbook.

Van Cleave uses terminology consistently and the chapters flow well. The textbook orients the reader by offering effective introductions to new material, step-by-step explanations of the material, as well as offering clear summaries of each lesson.

This textbook's modularity is really quite good. Its language and structure are not overly convoluted or too-lengthy, making it convenient for individual instructors to adapt the materials to suit their methodological preferences.

The topics in the textbook are presented in a logical and clear fashion. The structure of the chapters are such that it is not necessary to have to follow the chapters in their sequential order, and coverage of material can be adapted to individual instructor's preferences.

The textbook is free of any problematic interface issues. Topics, sections and specific content are accessible and easy to navigate. Overall it is user-friendly.

I did not find any significant grammatical issues with the textbook.

The textbook is not culturally insensitive, making use of a diversity of inclusive examples. Materials are especially effective for first-year critical thinking/logic students.

I intend to adopt Van Cleave's textbook for a Critical Thinking class I am teaching at the Community College level. I believe that it will help me facilitate student-learning, and will be a good resource to build additional classroom activities from the materials it provides.

While the book is admirably comprehensive, its extensive details within a few short chapters may feel overwhelming to students. The author tackles an impressive breadth of concepts in Chapter 1, 2, 3, and 4, which leads to 50-plus-page chapters that are dense with statistical analyses and critical vocabulary. These topics are likely better broached in manageable snippets rather than hefty single chapters.

The ideas addressed in Introduction to Logic and Critical Thinking are accurate but at times notably political. While politics are effectively used to exemplify key concepts, some students may be distracted by distinct political leanings.

The terms and definitions included are relevant, but the examples are specific to the current political, cultural, and social climates, which could make the materials seem dated in a few years without intentional and consistent updates.

While the reasoning is accurate, the author tends to complicate rather than simplify -- perhaps in an effort to cover a spectrum of related concepts. Beginning readers are likely to be overwhelmed and under-encouraged by his approach.

Consistency rating: 3

The four chapters are somewhat consistent in their play of definition, explanation, and example, but the structure of each chapter varies according to the concepts covered. In the third chapter, for example, key ideas are divided into sub-topics numbering from 3.1 to 3.10. In the fourth chapter, the sub-divisions are further divided into sub-sections numbered 4.1.1-4.1.5, 4.2.1-4.2.2, and 4.3.1 to 4.3.6. Readers who are working quickly to master new concepts may find themselves mired in similarly numbered subheadings, longing for a grounded concepts on which to hinge other key principles.

Modularity rating: 3

The book's four chapters make it mostly self-referential. The author would do well to beak this text down into additional subsections, easing readers' accessibility.

The content of the book flows logically and well, but the information needs to be better sub-divided within each larger chapter, easing the student experience.

The book's interface is effective, allowing readers to move from one section to the next with a single click. Additional sub-sections would ease this interplay even further.

Grammatical Errors rating: 4

Some minor errors throughout.

For the most part, the book is culturally neutral, avoiding direct cultural references in an effort to remain relevant.

This textbook covers enough topics for a first-year course on logic and critical thinking. Chapter 1 covers the basics as in any standard textbook in this area. Chapter 2 covers propositional logic and categorical logic. In propositional logic, this textbook does not cover suppositional arguments, such as conditional proof and reductio ad absurdum. But other standard argument forms are covered. Chapter 3 covers inductive logic, and here this textbook introduces probability and its relationship with cognitive biases, which are rarely discussed in other textbooks. Chapter 4 introduces common informal fallacies. The answers to all the exercises are given at the end. However, the last set of exercises is in Chapter 3, Section 5. There are no exercises in the rest of the chapter. Chapter 4 has no exercises either. There is index, but no glossary.

The textbook is accurate.

The content of this textbook will not become obsolete soon.

The textbook is written clearly.

The textbook is internally consistent.

The textbook is fairly modular. For example, Chapter 3, together with a few sections from Chapter 1, can be used as a short introduction to inductive logic.

The textbook is well-organized.

There are no interface issues.

I did not find any grammatical errors.

This textbook is relevant to a first semester logic or critical thinking course.

This text is a beginner textbook for arguments and propositional logic. It covers the basics of identifying arguments, building arguments, and using basic logic to construct propositions and arguments. It is quite comprehensive for a beginner book, but seems to be a good text for a course that needs a foundation for arguments. There are exercises on creating truth tables and proofs, so it could work as a logic primer in short sessions or with the addition of other course content.

The books is accurate in the information it presents. It does not contain errors and is unbiased. It covers the essential vocabulary clearly and givens ample examples and exercises to ensure the student understands the concepts

The content of the book is up to date and can be easily updated. Some examples are very current for analyzing the argument structure in a speech, but for this sort of text understandable examples are important and the author uses good examples.

The book is clear and easy to read. In particular, this is a good text for community college students who often have difficulty with reading comprehension. The language is straightforward and concepts are well explained.

The book is consistent in terminology, formatting, and examples. It flows well from one topic to the next, but it is also possible to jump around the text without loosing the voice of the text.

The books is broken down into sub units that make it easy to assign short blocks of content at a time. Later in the text, it does refer to a few concepts that appear early in that text, but these are all basic concepts that must be used to create a clear and understandable text. No sections are too long and each section stays on topic and relates the topic to those that have come before when necessary.

The flow of the text is logical and clear. It begins with the basic building blocks of arguments, and practice identifying more and more complex arguments is offered. Each chapter builds up from the previous chapter in introducing propositional logic, truth tables, and logical arguments. A select number of fallacies are presented at the end of the text, but these are related to topics that were presented before, so it makes sense to have these last.

The text is free if interface issues. I used the PDF and it worked fine on various devices without loosing formatting.

1. The book contains no grammatical errors.

The text is culturally sensitive, but examples used are a bit odd and may be objectionable to some students. For instance, President Obama's speech on Syria is used to evaluate an extended argument. This is an excellent example and it is explained well, but some who disagree with Obama's policies may have trouble moving beyond their own politics. However, other examples look at issues from all political viewpoints and ask students to evaluate the argument, fallacy, etc. and work towards looking past their own beliefs. Overall this book does use a variety of examples that most students can understand and evaluate.

My favorite part of this book is that it seems to be written for community college students. My students have trouble understanding readings in the New York Times, so it is nice to see a logic and critical thinking text use real language that students can understand and follow without the constant need of a dictionary.

This textbook is quite thorough--there are conversational explanations of argument structure and logic. I think students will be happy with the conversational style this author employs. Also, there are many examples and exercises using current events, funny scenarios, or other interesting ways to evaluate argument structure and validity. The third section, which deals with logical fallacies, is very clear and comprehensive. My only critique of the material included in the book is that the middle section may be a bit dense and math-oriented for learners who appreciate the more informal, informative style of the first and third section. Also, the book ends rather abruptly--it moves from a description of a logical fallacy to the answers for the exercises earlier in the text.

The content is very reader-friendly, and the author writes with authority and clarity throughout the text. There are a few surface-level typos (Starbuck's instead of Starbucks, etc.). None of these small errors detract from the quality of the content, though.

One thing I really liked about this text was the author's wide variety of examples. To demonstrate different facets of logic, he used examples from current media, movies, literature, and many other concepts that students would recognize from their daily lives. The exercises in this text also included these types of pop-culture references, and I think students will enjoy the familiarity--as well as being able to see the logical structures behind these types of references. I don't think the text will need to be updated to reflect new instances and occurrences; the author did a fine job at picking examples that are relatively timeless. As far as the subject matter itself, I don't think it will become obsolete any time soon.

The author writes in a very conversational, easy-to-read manner. The examples used are quite helpful. The third section on logical fallacies is quite easy to read, follow, and understand. A student in an argument writing class could benefit from this section of the book. The middle section is less clear, though. A student learning about the basics of logic might have a hard time digesting all of the information contained in chapter two. This material might be better in two separate chapters. I think the author loses the balance of a conversational, helpful tone and focuses too heavily on equations.

Consistency rating: 4

Terminology in this book is quite consistent--the key words are highlighted in bold. Chapters 1 and 3 follow a similar organizational pattern, but chapter 2 is where the material becomes more dense and equation-heavy. I also would have liked a closing passage--something to indicate to the reader that we've reached the end of the chapter as well as the book.

I liked the overall structure of this book. If I'm teaching an argumentative writing class, I could easily point the students to the chapters where they can identify and practice identifying fallacies, for instance. The opening chapter is clear in defining the necessary terms, and it gives the students an understanding of the toolbox available to them in assessing and evaluating arguments. Even though I found the middle section to be dense, smaller portions could be assigned.

The author does a fine job connecting each defined term to the next. He provides examples of how each defined term works in a sentence or in an argument, and then he provides practice activities for students to try. The answers for each question are listed in the final pages of the book. The middle section feels like the heaviest part of the whole book--it would take the longest time for a student to digest if assigned the whole chapter. Even though this middle section is a bit heavy, it does fit the overall structure and flow of the book. New material builds on previous chapters and sub-chapters. It ends abruptly--I didn't realize that it had ended, and all of a sudden I found myself in the answer section for those earlier exercises.

The simple layout is quite helpful! There is nothing distracting, image-wise, in this text. The table of contents is clearly arranged, and each topic is easy to find.

Tiny edits could be made (Starbuck's/Starbucks, for one). Otherwise, it is free of distracting grammatical errors.

This text is quite culturally relevant. For instance, there is one example that mentions the rumors of Barack Obama's birthplace as somewhere other than the United States. This example is used to explain how to analyze an argument for validity. The more "sensational" examples (like the Obama one above) are helpful in showing argument structure, and they can also help students see how rumors like this might gain traction--as well as help to show students how to debunk them with their newfound understanding of argument and logic.

The writing style is excellent for the subject matter, especially in the third section explaining logical fallacies. Thank you for the opportunity to read and review this text!

This is a review of Introduction to Logic and Critical Thinking, an open source book version 1.4 by Matthew Van Cleave. The comparison book used was Patrick J. Hurley’s A Concise Introduction to Logic 12th Edition published by Cengage as well as the 13th edition with the same title. Lori Watson is the second author on the 13th edition.

Competing with Hurley is difficult with respect to comprehensiveness. For example, Van Cleave’s book is comprehensive to the extent that it probably covers at least two-thirds or more of what is dealt with in most introductory, one-semester logic courses. Van Cleave’s chapter 1 provides an overview of argumentation including discerning non-arguments from arguments, premises versus conclusions, deductive from inductive arguments, validity, soundness and more. Much of Van Cleave’s chapter 1 parallel’s Hurley’s chapter 1. Hurley’s chapter 3 regarding informal fallacies is comprehensive while Van Cleave’s chapter 4 on this topic is less extensive. Categorical propositions are a topic in Van Cleave’s chapter 2; Hurley’s chapters 4 and 5 provide more instruction on this, however. Propositional logic is another topic in Van Cleave’s chapter 2; Hurley’s chapters 6 and 7 provide more information on this, though. Van Cleave did discuss messy issues of language meaning briefly in his chapter 1; that is the topic of Hurley’s chapter 2.

Van Cleave’s book includes exercises with answers and an index. A glossary was not included.

Reviews of open source textbooks typically include criteria besides comprehensiveness. These include comments on accuracy of the information, whether the book will become obsolete soon, jargon-free clarity to the extent that is possible, organization, navigation ease, freedom from grammar errors and cultural relevance; Van Cleave’s book is fine in all of these areas. Further criteria for open source books includes modularity and consistency of terminology. Modularity is defined as including blocks of learning material that are easy to assign to students. Hurley’s book has a greater degree of modularity than Van Cleave’s textbook. The prose Van Cleave used is consistent.

Van Cleave’s book will not become obsolete soon.

Van Cleave’s book has accessible prose.

Van Cleave used terminology consistently.

About the book.

This is an introductory textbook in logic and critical thinking. The goal of the textbook is to provide the reader with a set of tools and skills that will enable them to identify and evaluate arguments. The book is intended for an introductory course that covers both formal and informal logic. As such, it is not a formal logic textbook, but is closer to what one would find marketed as a “critical thinking textbook.”

What Is Critical Thinking?

Critical thinking, also known as critical reasoning, is the ability to assess a situation and consider/understand various perspectives, all while acknowledging, extracting and deciphering facts, opinions and assumptions. Critical thinking tests are a sub-type of aptitude exams  or psychometric tests used in pre-employment assessment for jobs reacquiring advanced analytical and learning skills.

The Skills You Will Be Tested On

Critical thinking tests can have 5 major sections or sub-tests that assess and measure a variety of aspects.

1) Inference

In this section, you are asked to draw conclusions from observed or supposed facts. You are presented with a short text containing a set of facts you should consider as true.

Below the text is a statement that could be inferred from the text. You need to make a judgement on whether this statement is valid or not, based on what you have read.

Furthermore, you are asked to evaluate whether the statement is true, probably true, there is insufficient data to determine, probably false, or false.

For example: if a baby is crying and it is his feeding time, you may infer that the baby is hungry. However, the baby may be crying for other reasons—perhaps it is hot.

2) Recognising Assumptions

In this section, you are asked to recognise whether an assumption is justifiable or not.

Here you are given a statement followed by an assumption on that statement. You need to establish whether this assumption can be supported by the statement or not.

You are being tested on your ability to avoid taking things for granted that are not necessarily true. For example, you may say, "I’ll have the same job in three months," but you would be taking for granted the fact that your workplace won't make you redundant, or that you won’t decide to quit and explore various other possibilities.

You are asked to choose between the options of assumption made and assumption not made.

3) Deduction

This section tests your ability to weigh information and decide whether given conclusions are warranted.

You are presented with a statement of facts followed by a conclusion on what you have read. For example, you may be told, "Nobody in authority can avoid making uncomfortable decisions."

You must then decide whether a statement such as "All people must make uncomfortable decisions" is warranted from the first statement.

You need to assess whether the conclusion follows or the conclusion does not follow what is contained in the statement. You can read more about our  deductive logical thinking test resources here. 

4) Interpretation

This section measures your ability to understand the weighing of different arguments on a particular question or issue.

You are given a short paragraph to read, which you are expected to take as true. This paragraph is followed by a suggested conclusion, for which you must decide if it follows beyond a reasonable doubt.

You have the choice of conclusion follows and conclusion does not follow.

5) Evaluation of Arguments

In this section you are asked to evaluate the strength of an argument.

You are given a question followed by an argument. The argument is considered to be true, but you must decide whether it is a strong or weak argument, i.e. whether it is both important and directly related to the question.

critical thinking sample questions

Example 1: Argument Analysis

Read the following:

In a recent study, anthropologists surveyed 250 adults who own pets and 250 adults who do not own pets on their interpersonal capacities. The questions asked of both those who own pets and those who do not own pets included tests for 'computational requirements', that is, tuning in to all the little signals necessary to operate as a couple. While members of each group displayed outstanding interpersonal capacities, in general, the adults who own pets were much more empathetic than those who do not own pets. This indicates that people who are especially empathetic are more likely to adopt a pet in spite of the personal sacrifice and the occasional inconvenience than people who are less empathetic.

Which of the following is true?

  • Most of the people surveyed, whether they own pets or do not own pets, displayed outstanding interpersonal capacities.
  • The adoption of a pet involves personal sacrifice and occasional inconvenience.
  • People with high degrees of empathy are more likely to adopt pets than people with low degrees of empathy.
  • Interpersonal capacities entail tuning in to all the little signals necessary to operate as a couple.
  • A person's degree of empathy is highly correlated with his or her capacity for personal sacrifice.

The correct answer is C

Answer explanation: In a question of this type, the rule is very simple: the main conclusion of an argument is found either in the first or the last sentence. If, however, the main conclusion appears in the middle of an argument, it will begin with a signal word such as thus, therefore, or so. Regardless of where the main conclusion appears, the rest of the passage will give the reasons why the conclusion is true or should be adopted. The main conclusion in this passage is the last sentence, signaled by the words, 'This indicates that people who are especially empathetic are more likely to adopt a pet than people who are less empathetic'.

Example 2: Argument Practice

A: No. Differential bonuses have been found to create a hostile working environment, which leads to a decrease in the quality and quantity of products .

This argument is:

The correct answer is A (Strong)

Schema of the statement: Differential cash bonuses (productivity↑) → workplace↑

Explanation: This argument targets both the action and the consequences of the action on the object of the statement. It states that the action (implementing differential cash bonuses) has a negative effect on the workplace (a decrease in the quality and quantity of products). Therefore, it is an important argument, one that is relevant for the workplace. Note that this argument does not specifically target differential cash bonuses. Still, they are considered a sub-group of the subject of the argument (differential bonuses).

Example 3 – Interpretations 

Proposed assumption: Vicki and Bill encountered a personal battle because they couldn’t come to terms with their disease.

A. Conclusion follows

B. Conclusion does not follow

The correct answer is B (Conclusion does not follow)

It is plausible that the reason people who suffer from sleep apnoea encounter a personal battle is because of an inability to come to terms with this disease. However, since the passage does not provide an actual reason, you cannot reach this conclusion without reasonable doubt. 

The most common type of Critical Thinking Assessment is the Watson Glaser .

Critical Thinking Tests FAQs

What are critical thinking tests

What critical reasoning test am I most likely to take?

Very Likely the Watson-Glaser test

Another popular critical thinking assessment, Watson-Glaser is a well-established psychometric test produced by Pearson Assessments.

The Watson-Glaser test is used for two main purposes: job selection/talent management and academic evaluations. The Watson-Glaser test can be administered online or in-person.

What skills do critical reasoning test measure?

Critical Thinking can refer to various skills:

  • Defining the problem
  • Selecting the relevant information to solve the problem
  • Recognising assumptions that are both written and implied in the text
  • Creating hypotheses and selecting the most relevant and credible solutions
  • Reaching valid conclusions and judging the validity of inferences

Pearson TalentLens condenses critical thinking into three major areas:

  • R ecognise assumptions – the ability to notice and question assumptions, recognise information gaps or unfounded logic. Basically not taking anything for granted.
  • E valuate arguments – the ability to analyse information objectively without letting your emotions affect your opinion.
  • D raw conclusions – the ability to reach focused conclusions and inferences by considering diverse information, avoiding generalisations and disregarding information that is not available.

These are abilities that employers highly value in their employees, because they come into play in many stages of problem-solving and decision-making processes in the workplace, especially in business, management and law.

Why are critical thinking tests important to employers?

Critical thinking, or critical reasoning, is important to employers because they want to see that when dealing with an issue, you are able to make logical decisions without involving emotions.

Being able to look past emotions will help you to be open-minded, confident, and decisive—making your decisions more logical and sound.

What professions use critical thinking tests?

Watson Glaser tests are a form of psychometric assessment that fall under the category of critical thinking tests. They are designed to determine how well an individual can process information from a logical perspective, and then evaluate, analyse and make sound judgements. As such, they are commonly used in the recruitment process for professions that rely on these skills.

What is a Watson Glaser test?

Watson Glaser test is a comprehensive psychometric assessment that falls under the category of critical thinking tests. It is designed to determine how well an individual can process information from a logical perspective, and then evaluate, analyze and make sound judgments. Watson Glaser test is commonly used in the recruitment process for professions that rely on these skills.

Watson Glaser tests have been around since 1925 when they were first developed by American psychologists Goodwin Watson and Edwin Glaser. Subject to many revisions and improvements over the years, they are now produced by test publisher TalentLens and are considered one of the most trusted methods of evaluating critical reasoning.

Critical thinking is a complex skill that requires the ability to interpret information, differentiate fact from fallacy, draw evidence-based conclusions and identify sound arguments, all while remaining objective.

Like many critical thinking tests , the Watson Glaser test measures these skills through verbal information: that is, statements or passages of text from which an individual is required to make deductions and inferences, pinpoint assumptions needed to validate a proposition, and weigh up the strength of an argument.

These are inherent skills, more prominent in some than others. The Watson Glaser test, therefore, requires no prior knowledge. Success relies on existing knowledge being put to one side, the sole focus being the evidence laid out in each question.

You may be asked to sit a Watson Glaser test by the potential employer if applying for a graduate, professional or managerial level position in a sector where critical thinking is a prerequisite. Watson Glaser Critical Thinking Appraisal is most commonly used in the legal sector, but also the selection process of organizations like the Bank of England.

The test may be used for screening purposes in the initial stages of the hiring process, or at a later date as part of an assessment day .

What is the format of a Watson Glaser test?

The Watson Glaser test is a timed, multiple-choice assessment, the most recent version of which consists of 40 critical reasoning questions with a 30-minute time constraint.

Questions are split across five areas of logical reasoning ability:

Drawing inferences

To draw inferences is essential to make an educated guess based on the evidence in front of you, without being swayed by any pre-existing knowledge or subconscious bias.

You’ll be presented with a short paragraph, followed by a set of inferred statements. Potential employees need to critically analyse the information in the given paragraph to determine if these statements are true, probably true, false, probably false, or if there is insufficient proof to determine either way.

Recognising assumptions

Assumptions relating to what we understand to be true without needing solid proof. They are the underlying facts that give an argument its validity.

In this section of the test, you’ll be presented with a statement and a set of assumptions. If the statement relies on the assumption being true, you would mark it as ‘assumption made’.

If the assumption is irrelevant to the statement or bears no weight on its validity, you would mark it as ‘assumption not made.

Deductive reasoning is the act of arriving at a fact-based conclusion through a logical thought process. A deduction differs from an assumption in that it is what we take away from an argument, as opposed to the facts on which an argument needs to stand.

Based solely on the evidence presented in a statement or short paragraph, you’ll need to determine if a list of conclusions does or does not logically follow the information in front of you.

Interpreting

The interpretation section of the Watson Glaser test is similar to the deduction section, in that you’ll be asked to determine whether a given conclusion can logically be drawn from an argument.

However, with these questions, you’ll need to be able to identify significant pieces of information and decide if a logical interpretation can be applied in support of the conclusion in question.

Evaluating arguments

This last section looks at your ability to separate a weak argument from a strong one. It is designed to test your impartial evaluation of arguments, not your personal opinion.

A question will be posted, followed by a set of arguments on either side of the debate. You’ll need to decide if an argument is relevant and challenging, and therefore strong, or vague and unrealistic, and therefore weak.

What skills does it look to measure?

The five sections combined to give an overall picture of your performance in key areas, and measure your ability to:

Define a problem

Select key points of information to formulate a solution

Understand when an assumption has been made, and when it has not

Hypothesise, or select an applicable hypothesis based on limited evidence

Draw fact-based conclusions

Determine the probability of an inference

What is a passing score on the Watson Glaser tests?

The results of your Watson Glaser test will be assessed against a norm group: individuals of a comparative educational background or professional standing – within a relevant field – that have previously sat the exam.

It is therefore difficult to state an exact pass score on the test since it depends entirely on the performance of your peers. Ideally, you’d look to reach 75% and above to give yourself a competitive edge.

Which professions use Watson Glaser tests, and why?

Watson Glaser tests are used to assess suitability for several occupations including those in the medical profession, marketing, and education. Those critical reasoning tests are most common in law firms and professional services sectors.

Many positions in law, banking, and finance, for example, require that an individual make informed decisions that can be justified, are rooted in fact, and are free from bias. Since critical thinking is an essential skill here, employers use Watson Glaser tests to determine how well-suited a candidate is for these professions.

How to prepare for a Watson Glaser test

Practice is the first port of call when preparing for your Watson Glaser test. Although critical thinking is an inherent skill, it can be nurtured and improved upon.

Watson Glaser tests are built around a model known as RED . Try to keep this in mind as you approach both practice tests and daily tasks.

The components associated with the RED model are:

Recognising assumptions . Instead of simply taking things at face value, such as the news or a part of a conversation with a friend or co-worker, ask yourself if what you’re hearing can be classified as true, and what the facts are that back it up. Are they evidential, or based on assumptions?

Evaluating arguments . We’re all guilty of seeking out information that confirms our perspective. Instead, actively look for opinions that contradict your own and assess them from an objective point of view. The better you become at seeing both sides of a story, the more prepared you’ll be to critically evaluate arguments in your Watson Glaser test.

Drawing conclusions . Try to get used to drawing fact-based conclusions, rather than those based on emotional reactions or subconscious bias. These conclusions may not align with your perspective, but a Watson Glaser test requires that you conclude impartially – and as with most things in life, practice makes perfect here.

Tips for Watson Glaser tests

Study the practice questions.

In the official test, you’ll have the opportunity to complete practice questions. These are there for a reason, so use them wisely. Each section of the test differs slightly in its approach, and the more comfortable you are with what is being asked of you, the more clearly you’ll be able to approach the problem.

Leave instinct and intuition at the door

To succeed on a Watson Glaser test, you need to go against human nature and ignore everything you think you know. Each question will contain all the relevant information you need. Whether you believe it to be true, agree with it, or not, is irrelevant. For the sake of the test, evaluate only the information given. Any outside knowledge should temporarily be forgotten.

Examine each question carefully

The key to strategic critical thinking is to fully understand what is being presented. You cannot draw a valid conclusion, or understand what assumptions support an argument, if you do not fully comprehend what is put forward. You may feel the need to rush under the time pressure, but attention to detail is vital.

Look for keywords and phrases

The statement, proposition or paragraph of text at the start of each question will inevitably include keywords or phrases that relate directly to the assumptions, inferences or conclusions given. These are your clues. Identify them, and you’ll find it much easier to analyse each scenario objectively.

Split your time evenly

Remember, you have a set amount of time to work through all five sections of the test. Split this evenly across the board before you start, and keep track of how much time you spend on each question. It may seem counterintuitive to add to the pressure, but in setting yourself a time frame, you eliminate the risk of dedicated excessive attention to any one part of the test.

According to the methodology behind Watson Glaser tests, critical thinking is the ability to observe a scenario and consider it from various perspectives, whilst identifying what is fact, what is assumed and what is mere opinion. In doing so, you should be able to draw logical conclusions and use these for informed decision making.

How can I improve my critical thinking skills?

Critical thinking is a part of our daily lives; we’re just not always aware that we’re doing it. To improve your skills, tune in to the world around you, ask questions, read actively and look for evidence in every statement or argument you come across. Take practice tests regularly to assess your progress.

Is the Watson Glaser test hard?

Watson Glaser tests are considered among the most challenging of all critical thinking assessments, since they test five separate aspects of logical reasoning ability . Time constraints also add to the pressure. That said, they are typically no harder than the careers for which they test your suitability, and with dedicated practice, you can hone your skills and make critical thinking second nature.

Where can I practice Watson Glaser tests?

There are multiple online resources available to help you prepare for your Watson Glaser test, including our own free practice tests . We recommended you work through these questions to familiarise yourself with the format and improve your critical thinking skills.

Doesn't cover all aspects of Watson-Glaser tests but useful

The WGCTA uses more categories to assess critical thinking, but this was useful for the inference section.

Just practicing for an interview

Good information and liked that it had a countdown clock, to give you that real feel in the test situation.

Aptitude test

It was OK, I didn't understand personally whether or not the "cannot say" option was acceptable or not in a lot of the questions, as it may have been a trick option.

I like the test because the platform is simple and engaging while the test itself is different than most of the Watson Glaser tests I've taken.

Alexis Sheridan

Some of the ratios were harder than I thought!

I like how clear the design and layout is - makes things very easy (even if the content itself is not!)

Mental arithmetic

I enjoyed the fact that there were multiple questions pertaining to one passage of information, rather than multiple passages. However I would've appreciated a more varied question type.

Analytics are the best questions

I like the test because of its time schedule. The way the questions are prepared makes it easy to crack the original test.

Interesting

I haven't done something like this for ages. Very good for the brain - although I certainly experienced some fog whilst doing it.

Population/exchange rates were the hardest

Great test as it felt a bit time pressured. Very different types of questions in terms of difficulty.

More attention to detail + be more time conscious

It was asking about daily stuff we all deal with, but as an assessment it's scrutinising how we approach these problems.

Critical Thinking Test: Online Preparation & Free Practice Questions – 2024

Job Assessment

  • Information
  • Free Example Questions

What Is Critical Thinking?

Critical thinking is a form of decision making and reasoning using data and observations. Someone who is a strong critical thinker can find quality solutions efficiently and can evaluate issues objectively.

What Is a Critical Thinking Test?

Critical thinking tests provide companies valuable insight into the leadership, reasoning, and overall capabilities of candidates. Because strong critical thinking skills are highly sought after, the critical thinking test can be applicable to any field and discipline across multiple levels of expertise from recent graduate to executive. However, it is commonly administered to those applying for criminal justice and business-related occupations.

Job seekers with upcoming critical thinking tests will be evaluated on more than their ability to rationalize, critical thinking tests also measure the following subsets:

  • Organizing & Planning
  • Strategizing
  • Decision Making
  • Problem Solving

The format of the critical thinking uses hypothetical scenarios to assess candidates. The scenarios are typically relevant to the field you are interested in to assess your knowledge of the role. There will also be general questions concerning more basic issues or problems that commonly occur in a workplace environment.

The critical thinking test is multiple-choice with thirty minutes to complete the assessment. Candidates will receive a notification stating whether or not they passed within a week of completion.

How Is the Critical Thinking Test Scored?

The critical reasoning test is scored based on your raw score and your percentile in comparison with your norm group. It’s important to note that these will not be the same number.

A norm group is a collection of scores from individuals in your field at your level of experience. The percentile score is used to alert employers if you exceed, meet or miss the benchmark for the average expectations of candidates. You will be rated on a scale of one to one hundred with fifty consisting of the mean and median scores.

A raw score is simply the number of correct answers. The critical thinking test comprises your raw score based on the performance in the following areas:

  • Recognizing Assumptions The candidate must be able to understand when a statement is made with no supporting evidence and how this can affect a decision. Further, candidates are asked to identify these discrepancies, whether they are stated explicitly or implicitly, and assess its relevance to the given scenario.
  • Evaluating Arguments Candidates must evaluate arguments without considering inferences or being subjective. Beyond that, candidates must assess the supporting evidence, the structure of the argument and the degree of its influence. It is very important to dismiss emotions for this portion of the critical thinking test.
  • Drawing Conclusions Drawing conclusions puts a large emphasis on reasoning. In this section, it’s important to assess all of the available evidence and data to form a plausible conclusion that accurately applies to all the given information. Employers also want to see candidates that will consider all possible solutions rather than making the evidence fit a desired narrative.

Employers will receive all of this information in a performance report construed by the assessment company. Employers will also be given insight into your overall potential, job knowledge, creativity and job performance per the report.

Where Will I Take a Critical Thinking Test?

Critical thinking tests are non-proctored online assessments that are typically sent via email after an initial screening. For some occupations, the company may ask that the candidate take the critical thinking test again on-site either before their final interview or during an assessment day. The most common test candidates are asked to take is the Watson Glaser Critical Thinking Appraisal (WGCTA) created by the popular assessment company, Pearson . This assessment company is on their third edition with new scoring and subsets described above. The WGCTA gained popularity because of its ability to assess a candidate’s potential alongside their aptitude. Another established assessment is the SHL Critical Reasoning Battery that contains sixty questions with a thirty-minute time limit. Both of the aforementioned critical thinking tests are multiple choice.

How to Prepare for the Critical Thinking Test?

The critical thinking test is difficult to study for because the test is designed to assess your bare knowledge and raw skills. In order to prepare successfully, it is important to focus on the areas of the test that you can equip yourself for. One aspect of the test that demands preparation is the time limit. Many candidates’ scores are negatively impacted because they skip or guess too many of the questions in an attempt to beat the clock. If you want to optimize your chances of achieving a good score, use online practice tests to acquaint yourself with the time constraint and the general theme of the questions. By utilizing the online practice tests, you can find the pace that works best for you. Another helpful way to prepare is running through sample questions. This way, you can warm-up your brain and gain an understanding of the expectations that both the test and the company have of you.

Critical thinking puzzles for adults (with answers)

critical thinking puzzles

Critical thinking can help to better navigate the information-dense and complex world we live in. By thinking critically we can better identify priorities, take a sensible approach to problem-solving and reach conclusions logically in line with evidence. Puzzles are an excellent way both to learn and practice critical thinking skills.

If you’d like to learn more about critical thinking or simply practice your skills with some puzzles, then this is the article for you. Read a little bit more about critical thinking skills and how to apply them first, or just skip straight to the puzzles and see how you get on.

What is critical thinking?

Critical thinking is a broad approach to problem solving and analysis based on logic and evidence. It brings together a wide range of intellectual competences and the ability to combine and cross-reference them. Some of the most important elements of a critical thinking approach include:

Analytical skills:

  • understanding of questions and concepts
  • differentiation of relevant / irrelevant evidence and information
  • identification of similarities, connections and differences
  • use of metaphors or analogies to communicate ideas

Powers of inference:

  • extraction of meaning from data using inductive or deductive reasoning
  • extrapolation of data or abstraction into concepts and patterns
  • correct identification and deployment of analogies and assumptions
  • grasp of causal relationships, allowing development of conclusions and theories.

Data and theory evaluation:

  • assessment of how strong, important or credible a theory might be
  • taking on board new data and new arguments which alter understanding of ideas and theory

Rational decision-making:

– application of all the skills and competences above in order to come to a rational conclusion.

Problem-solving attitude: In addition to being able to think critically, you must also be personally inclined to think critically when facing a difficult or complex challenge. Developing qualities including curiosity and fairness, while distancing yourself from ideologies and group-think, should all help to create the kind of psychological landscape where critical thinking can flourish.

How can I learn critical thinking?

Critical thinking skills are hard to develop from only reading books or listening to lectures. The most effective way to sharpen and deepen critical thinking faculties is to practice critical thinking . Critical thinking puzzles offer a fun way to learn and the eight critical thinking puzzles we’ve chosen for this article should help you make a good start.

CAN YOU HANDLE IT?..

Eight critical thinking puzzles – with answers

Puzzle 1 – letter puzzles.

What common feature do the following words share?

Answer: All of these words begin with a vowel. This type of puzzle may send your mind off in the wrong direction, thinking about the objects or concepts described by the words, and the properties they might share. In fact, the solution lies in a far more simple consideration of the alphabet. Puzzle 1 is a simple example of a common type of letter or word puzzle.

Puzzle 2 – Commonalities and differences

What do the following items have in common and which is the odd one out?

Orange Juice

Answer: These items are all liquids and the odd one out is petrol, since all the others are drinkable liquids.

Puzzle 3 – Falling on his feet

A man who lives in a high-rise building decides to exit through the window one morning rather than using the door. Somehow he survives the fall without a scratch and walks away to work. How did this happen?

Answer: The man lived on the ground or first floor and merely stepped or jumped down to the pavement outside. By stating early on that the building in question was a high-rise building, it’s easy for someone reading quickly to assume that the man jumped from a window on a high store but this it s not necessarily the case.

Puzzle 4 – Walk this way

A group of five people enter a windowless meeting room together. An hour later when the meeting ends, four walk out of the door, leaving the room empty. What has happened to the fifth member of the group?

Answer: The fifth person was in a wheelchair and wheeled out of the room rather than walked. Solving this puzzle requires you to think laterally about the question and the possible solutions. The answer can be found by asking yourself whether the emphasis of the question is on the emptiness of the room or the means by which the other four people left.

Puzzle 5 – Shapes and symbols

When lying on my side, I am everything, but when cut in half, I am nothing. What am I?

Answer: The number 8. This puzzle requires that you think about a shape being repositioned or cut in a way that can change it to “everything” or “nothing”. Number 8 on its side is the mathematical symbol for infinity (i.e. everything) and also shaped like two small number 0s put together.

Puzzle 6 – Three hard options

The hero is escaping the lair of an evil super-villain and is faced with three possible exits:

  • Door A leads into a pit of bubbling lava
  • Door B leads to a room housing a deadly hitman
  • Door C leads to the den full of lions that haven’t had a meal for a year.

Which door should the hero choose?

Answer: Door C. If the lion hasn’t eaten in a year, it will definitely be dead by now. This type of puzzle requires you to consider the full implications of the information given, rather than being drawn into a comparison of the relative dangers of lava, hitmen and lions…

Puzzle 7 – The bus driver’s eyes

You are a bus driver. Today the bus is empty at the start of your route but at the first stop, four people get onto the bus. Eight people get on at the second stop, while three alight. When the bus reaches the third stop, one more gets off, and three get on.

At the fourth stop, two people get off the bus and one gets on. The bus is traveling at an average speed of 30mph and its tires are new.  What color are the bus driver’s eyes?

Answer: You are the bus driver so the color will be the color of your own eyes. This type of puzzle tries to confuse you and obscure the single piece of relevant information by presenting large quantities of irrelevant information.

Puzzle 8 – Losing weight

A man walks into a room, closes the doors behind him and presses a button. In a matter of seconds the man is 20lb lighter. Despite this, he leaves the room at the same weight he entered it.

Answer: The room in question is actually an elevator. When the man gets in and presses the button, the elevator moves downwards with an acceleration that reduces the effect of gravity and makes the man temporarily 20lb lighter. Once the lift stops moving, the man’s weight is subject to normal gravity, just the same as before. Solving this puzzle requires a small piece of general physics knowledge.

A final word…

We hope you’ve enjoyed our critical thinking puzzles for adults and that your critical thinking skills are feeling refreshed and sharpened after reading our article. Whether at school, in the workplace, or in general life, critical thinking can be a valuable tool for success and anyone can learn to use it.
