an effective thesis statement has the following three characteristics

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

• Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
• Makes a promise to the reader about the scope, purpose, and direction of your paper.
• Is focused and specific enough to be “proven” within the boundaries of your paper.
• Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
• Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

• Franco first tried to negotiate with the Axis
• Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.

• The simile compares Simoisius to a tree, which is a peaceful, natural image.
• The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

• This paper will look at modern language to see if it reflects male dominance or female oppression.
• I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

• nature = peaceful
• war matériel = violent (competes with 1?)
• need for time and space to mourn the dead
• war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

• although most readers of _______ have argued that _______, closer examination shows that _______.
• _______ uses _______ and _____ to prove that ________.
• phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

• Ask if your draft thesis addresses the assignment
• Question each part of your draft thesis
• Clarify vague phrases and assertions
• Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

• Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.

Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.

Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.

While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.

While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

• Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
• As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
• Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
• Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

Thesis Statements

A thesis statement is a sentence (sometimes more than one sentence) in the introduction that tells the reader the following information:

• What the topic of the paper is
• How the writer intends to discuss that topic
•  It gives a blueprint for how the essay will be structured
•  How the writer intends to prove or demonstrate his or her main points.

Think of your paper as a human body, and your thesis statement as the spinal cord. Without it, there is no structure.

For you as the writer, the thesis statement:

Develops through the interrelationship of thinking, reading, and writing;

Limits your research by providing you with one controlling main idea that intrigues you;

Narrows your writing to one specific claim that you can develop or prove;

Organizes your ideas so you know the important points you want to make in your paper; and

Clarifies your writing by keeping you on target to fulfill your proposed purpose.

For your readers, the thesis statement:

 Identifies the main point and sub-points of your essay clearly and quickly;

Functions as a road map so your readers can easily follow your ideas; and

Gives satisfaction at the conclusion of the paper when your readers discover you have fulfilled your promise by proving or developing your main point.

Characteristics of Effective Thesis Statements

An effective thesis statement must be  factual and narrow.

An effective thesis statement prepares readers for facts and details, but it cannot itself be a fact. It must always be an inference that demands proof or further development. These proofs come from the literature. 

UNT Dallas campus has two buildings.

Not factual enough: The UNT Dallas campus is the perfect size.

Just Right:  While some might see small universities as a disadvantage, the small campus of UNT Dallas holds many advantages for students, including a close-knit campus community, smaller class sizes, and better support from professors.

2. Narrow Topic

A good thesis should be narrow, and not too broad or too vague. If the topic is too broad, you won’t be able to cover the entire topic in your paper.  If it’s too narrow, you might not be able to find research, and your paper probably won’t be long enough. 

Too Broad: College students have a lot of responsibilities.

Too Narrow: Student workers in the Learning Commons at UNT Dallas have many responsibilities in their course work and tutoring. 

Just Right: College students who are financially independent have many responsibilities as they must maintain good grades, pay living expenses, and balance work and school.

Remember, a thesis statement is not: 

• Instead , you should argue, based on facts and literature, why or why not NASA should receive more funding.  
• Ask yourself--can I find anything in literature to prove this point, or is this MY opinion? 
• Instead, you should argue why or why not people like chocolate OR why or why not chocolate is healthy for you based on facts and literature findings. 
• Similar to the subjective opinion, ask yourself is this statement is based on facts and literature findings or if this is YOUR opinion. Although it is ok to have your own opinion, professors usually do not like to read articles about beliefs (students have been writing about these for years and years). 
• Instead, you could discuss theories about politics or religions and use literature to prove or disprove those theories.
• This is too factual (the Himalayas WERE formed from a collision of tectonic plates), and there is nothing to discuss because this IS a fact in itself. 
• Instead, you could compare and contrast the tectonic plate formation of different mountains. 

Examples of Thesis Statements

A thesis statement f or a 5 paragraph essay conta ins three parts:.

1. A Topic: the main idea of the essay

2. The Controlling Idea: what you want to say about the topic

3. The subtopics: usually 3 examples/reasons you will discuss in your paper

Here is an example  of a thesis statement.

Ex: Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.

The main topic explores the idea that regularly vsiting the writing center will help you become the best writer on the planet, and the subtopics further expand this opinion with three distinct examples: 1) tutors, 2) technology, and 3) the handouts.

Outline Example

The paper should be organized around the subtopics.  For example, for the thesis written above, the writer would write one body paragraph about the tutors, one about technology, and one about the handouts. 

Here is a sample essay outline based on this thesis:

• Introduce the topic of tutoring
• Thesis (last sentence of intro): Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.
• topic sentence
• Restate thesis
• Concluding remarks

For further assistance with the structure, see our handouts on Introductions and Conclusions and Topic Sentences.

A thesis statement for a LONG ESSAY contains two parts: A Topic: the main idea of the essay The Controlling Idea: what you want to say about the topic 

Throughout the paper, your thesis promises your readers that you will prove specific facts or develop certain ideas ; therefore, every paragraph, sentence, and word in your paper must relate to this controlling idea.

Here are some examples of thesis statements.

• Baseball, once a national pastime and even an addiction, has lost its popularity because of the new interest in more violent sports.
• Since the space program has yet to provide the American people with any substantial, practical returns, it is a waste of money and should be dissolved.
• To stop the alarming rise in the number of violent crimes committed every year, our courts must hand out tougher sentences.
• Detective stories appeal to the basic human desire for thrills.
• Hemingway's war stories helped to create a new prose style.
• Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Here is a suggested outline for a long essay and how that would look in terms of your thesis statement, topic, and controlling ideas:

• Introduce the novel Jane Eyre and the topic of symbolism
• Thesis (last sentence of intro): Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Learning Objectives

• Identify strong thesis statements

The thesis statment is the key to most academic writing. The purpose of academic writing is to offer your own insights, analyses, and ideas—to show not only that you understand the concepts you’re studying, but also that you have thought about those concepts in your own way and agreed or disagreed, or developed your own unique ideas as a result of your analysis. The thesis statement is the one sentence that encapsulates the result of your thinking, as it offers your main insight or argument in condensed form.

We often use the word “argument” in English courses, but we do not mean it in the traditional sense of a verbal fight with someone else. Instead, you “argue” by taking a position on an issue and supporting it with evidence. Because you’ve taken a position about your topic, someone else may be in a position to disagree (or argue) with the stance you have taken. Think about how a lawyer presents an argument or states their case in a courtroom—similarly, you want to build a case around the main idea of your essay. For example, in 1848, when Elizabeth Cady Stanton drafted “The Declaration of Sentiments,” she was thinking about how to convince New York State policymakers to change the laws to allow women to vote. Stanton was making an argument .

Some consider all writing a form of argument—or at least of persuasion. After all, even if you’re writing a letter or an informative essay, you’re implicitly trying to persuade your audience to care about what you’re saying. Your thesis statement represents the main idea—or point—about a topic or issue that you make in an argument. For example, let’s say that your topic is social media. A thesis statement about social media could look like one of the following sentences:

• Social media are hurting the communication skills of young Americans.
• Social media are useful tools for social movements.

A basic thesis sentence has two main parts:

• Topic: What you’re writing about
• Angle: What your main idea is about that topic

Example Thesis Statements

Thesis: A regular exercise regime leads to multiple benefits, both physical and emotional.

Topic: Regular exercise regime

Angle: Leads to multiple benefits

Thesis: Adult college students have different experiences than typical, younger college students.

Topic: Adult college students

Angle: Have different experiences

Thesis: The economics of television have made the viewing experience challenging for many viewers because shows are not offered regularly, similar programming occurs at the same time, and commercials are rampant.

Topic: Television viewing

Angle: Challenging because shows shifted, similar programming, and commercials

Identifying the Thesis Statement

You’ll remember that the first step of the reading process, previewing , allows you to get a big-picture view of the document you’re reading. This way, you can begin to understand the structure of the overall text. The most important step in getting a good understanding of an essay or book is to find the thesis statement.

A thesis consists of a specific topic and an angle on the topic. All of the other ideas in the text support and develop the thesis. The thesis statement is often found in the introduction, sometimes after an initial “hook” or interesting story; sometimes, however, the thesis is not explicitly stated until the end of an essay, and sometimes it is not stated at all. In those instances, there is an implied thesis statement, in which you can generally extract the thesis statement by looking for a few key sentences and ideas.

Most readers expect to see the point of your argument (the thesis statement) within the first few paragraphs. This does not mean that it has to be placed there every time. Some writers place it at the very end, slowly building up to it throughout their work, to explain a point after the fact. Others don’t bother with one at all but feel that their thesis is “implied” anyway. Beginning writers, however, should avoid the implied thesis unless certain of the audience. Almost every professor will expect to see a clearly discernible thesis sentence in the introduction.

Thesis statements vary based on the rhetorical strategy of the essay, but thesis statements typically share the following characteristics:

• Presents the main idea
• Most often is one sentence
• Tells the reader what to expect
• Is a summary of the essay topic
• Usually worded to have an argumentative edge
• Written in the third person

The following “How to Identify a Thesis Statement” video offers advice for locating a text’s thesis statement. It asks you to write one or two sentences that summarize the text. When you write that summary, without looking at the text itself, you’ve most likely paraphrased the thesis statement.

You can view the transcript for “How to Identify the Thesis Statement” here (download).

Writing a Thesis Statement

Remember your thesis should answer two simple questions: What issue are you writing about, and what is your position, or angle, on it?

A thesis statement is a single sentence (or sometimes two) that provides the answers to these questions clearly and concisely. Ask yourself, “What is my paper about, exactly?” to help you develop a precise and directed thesis, not only for your reader, but for you as well.

A good thesis statement will:

• Consist of just one idea
• Make your position clear
• Be specific
• Have evidence to support it
• Be interesting
• Be written clearly

A good basic structure for a thesis statement is “they say, I say.” What is the prevailing view, and how does your position differ from it? However, avoid limiting the scope of your writing with an either/or thesis under the assumption that your view must be strictly contrary to their view.

Following are some typical thesis statements:

• Although many readers believe Romeo and Juliet to be a tale about the ill fate of two star-crossed lovers, it can also be read as an allegory concerning a playwright and his audience.
• The “War on Drugs” has not only failed to reduce the frequency of drug-related crimes in America but actually enhanced the popular image of dope peddlers by romanticizing them as desperate rebels fighting for a cause.
• The bulk of modern copyright law was conceived in the age of commercial printing, long before the Internet made it so easy for the public to compose and distribute its own texts. Therefore, these laws should be reviewed and revised to better accommodate modern readers and writers.
• The usual moral justification for capital punishment is that it deters crime by frightening would-be criminals. However, the statistics tell a different story.
• If students really want to improve their writing, they must read often, practice writing, and receive quality feedback from their peers.
• Plato’s dialectical method has much to offer those engaged in online writing, which is far more conversational in nature than print.

Thesis Problems to Avoid

Although you have creative control over your thesis sentence, you still should try to avoid the following problems, not for stylistic reasons, but because they indicate a problem in the thinking that underlies the thesis sentence.

• For example, look at the thesis: Hospice workers need support. This is a thesis sentence; it has a topic (hospice workers) and an angle (need support). But the angle is very broad. When the angle in a thesis sentence is too broad, the writer may not have carefully thought through the specific support for the rest of the writing. A thesis angle that’s too broad makes it easy to fall into the trap of offering information that deviates from that angle.
• Consider this thesis: Hospice workers have a 55% turnover rate compared to the general health care population’s 25% turnover rate. This sentence really isn’t a thesis sentence at all, because there’s no angle idea to support. A narrow statistic, or a narrow statement of fact, doesn’t offer the writer’s own ideas or analysis about a topic. A clearer example of a thesis statement with an angle of development would be the following:

• Effective Thesis Statements

What is a Thesis Statement?

• A thesis statement tells a reader how you will interpret the significance of the subject matter under discussion. Such a statement is also called an “argument,” a “main idea,” or a “controlling idea.”
• A good thesis has two parts. It should tell what you plan to argue, and it should “telegraph” how you plan to argue—that is, what particular support for your claim is going where in your essay
• A standard place for your thesis is at the end of the introductory paragraph.
• A thesis is an interpretation of a subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel that others might dispute.
• A strong thesis not only grabs the interest of your reader, who now wants to see you support your unique interpretation, it also provides a focus for your argument, one to which every part of your paper refers in the development of your position.
• A thesis keeps the writer centered on the matter at hand and reduces the risk of intellectual wandering. Likewise, a thesis provides the reader with a “road map,” clearly laying out the intellectual route ahead.
• A thesis statement avoids the first person (“I believe,” “In my opinion”).

A simple equation for what a thesis might look like this:

What you plan to argue + How you plan to argue it = Thesis Specific Topic+ Attitude/Angle/Argument=Thesis

Steps To Write Effective Thesis Statement

• Choose a prompt or, if appropriate, select a topic: television violence and children
• What are the effects of television violence on children?
• Violence on television increases aggressive behavior in children.
• Avoid general phrasing and/or sweeping words such as “all” or “none” or “every”.
• Lead the reader toward the topic sentences (the subtopics needed to prove the thesis).
• While poor parenting and easy access to weapons may act as contributory factors, in fact when children are exposed to television violence they become less sensitive to the pain and suffering of others, are more fearful of the world around them, and are more likely to behave in aggressive or harmful ways toward others.

The Components of an Effective Thesis Statement

• You can’t just pluck a thesis out of thin air. Even if you have a terrific insight concerning a topic, it won’t be worth much unless you can logically and persuasively support it in the body of your essay. A thesis is the evolutionary result of a thinking process, not a miraculous creation. Formulating a thesis is not the first thing you do after reading an essay assignment .
• Substantial – Your thesis should be a claim for which it is easy to answer every reader’s question: “So what?”
• Supportable – A thesis must be a claim that you can prove with the evidence at hand (e.g., evidence from your texts or from your research). Your claim should not be outlandish, nor should it be mere personal opinion or preference (e.g., “Frederick Douglass is my favorite historical figure.”) It tackles a subject that could be adequately covered in the format of the project assigned.
• Precise – It is focused and specific. A strong thesis proves a point without discussing everything. It clearly asserts your own conclusion based on evidence. Note: Be flexible. It is perfectly okay to change your thesis!
• Arguable – It should be contestable, proposing an arguable point with which people could reasonably disagree.
• Relevant – If you are responding to an assignment, the thesis should answer the question your teacher has posed. In order to stay focused, pay attention to the task words in the assignment: summarize, argue, compare/contrast, etc.
• Aware of Counters – It anticipates and refutes the counter-arguments.

The best thesis statement is a balance of specific details and concise language. Your goal is to articulate an argument in detail without burdening the reader with too much information.

Questions To Review Your Thesis

• “Do I answer the question?” This might seem obvious, but it’s worth asking. No matter how intriguing or dazzling, a thesis that doesn’t answer the question is not a good thesis!
• “Have I taken a position that others might challenge or oppose?” If not, then you probably do not have a strong argument. Theses that are too vague often have this problem. If your thesis contains vague words like “good” or “successful,” see if you could be more specific: why is something “good”; what makes something “successful”?
• Would anyone possible care about this thesis? So What? Does your thesis present a position or an interpretation worth pursuing? If a reader’s first response is, “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• “Does my essay support my thesis specifically and without wandering?” Just as a thesis that doesn’t answer the question ultimately fails, so does a thesis that isn’t properly supported with evidence and reasoning.
• Does my thesis statement adequately address the direction words of the prompt: summarize, argue, compare/contrast, analyze, discuss, etc.?

Myths about Thesis Statements

• Every paper requires one . Assignments that ask you to write personal responses or to explore a subject don’t want you to seem to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.
• A thesis statement must come at the end of the first paragraph . This is a natural position for a statement of focus, but it’s not the only one. Some theses can be stated in the opening sentences of an essay; others need a paragraph or two of introduction; others can’t be fully formulated until the end.
• A thesis statement must be one sentence in length , no matter how many clauses it contains. Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.
• You can’t start writing an essay until you have a perfect thesis statement . It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. And some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.
• A thesis statement must give three points of support . It should indicate that the essay will explain and give evidence for its assertion, but points don’t need to come in any specific number.

How to Write a Strong Thesis Statement: 4 Steps + Examples

What’s Covered:

What is the purpose of a thesis statement, writing a good thesis statement: 4 steps, common pitfalls to avoid, where to get your essay edited for free.

When you set out to write an essay, there has to be some kind of point to it, right? Otherwise, your essay would just be a big jumble of word salad that makes absolutely no sense. An essay needs a central point that ties into everything else. That main point is called a thesis statement, and it’s the core of any essay or research paper.

You may hear about Master degree candidates writing a thesis, and that is an entire paper–not to be confused with the thesis statement, which is typically one sentence that contains your paper’s focus. 

Read on to learn more about thesis statements and how to write them. We’ve also included some solid examples for you to reference.

Typically the last sentence of your introductory paragraph, the thesis statement serves as the roadmap for your essay. When your reader gets to the thesis statement, they should have a clear outline of your main point, as well as the information you’ll be presenting in order to either prove or support your point. 

The thesis statement should not be confused for a topic sentence , which is the first sentence of every paragraph in your essay. If you need help writing topic sentences, numerous resources are available. Topic sentences should go along with your thesis statement, though.

Since the thesis statement is the most important sentence of your entire essay or paper, it’s imperative that you get this part right. Otherwise, your paper will not have a good flow and will seem disjointed. That’s why it’s vital not to rush through developing one. It’s a methodical process with steps that you need to follow in order to create the best thesis statement possible.

Step 1: Decide what kind of paper you’re writing

When you’re assigned an essay, there are several different types you may get. Argumentative essays are designed to get the reader to agree with you on a topic. Informative or expository essays present information to the reader. Analytical essays offer up a point and then expand on it by analyzing relevant information. Thesis statements can look and sound different based on the type of paper you’re writing. For example:

• Argumentative: The United States needs a viable third political party to decrease bipartisanship, increase options, and help reduce corruption in government.
• Informative: The Libertarian party has thrown off elections before by gaining enough support in states to get on the ballot and by taking away crucial votes from candidates.
• Analytical: An analysis of past presidential elections shows that while third party votes may have been the minority, they did affect the outcome of the elections in 2020, 2016, and beyond.

Step 2: Figure out what point you want to make

Once you know what type of paper you’re writing, you then need to figure out the point you want to make with your thesis statement, and subsequently, your paper. In other words, you need to decide to answer a question about something, such as:

• What impact did reality TV have on American society?
• How has the musical Hamilton affected perception of American history?
• Why do I want to major in [chosen major here]?

If you have an argumentative essay, then you will be writing about an opinion. To make it easier, you may want to choose an opinion that you feel passionate about so that you’re writing about something that interests you. For example, if you have an interest in preserving the environment, you may want to choose a topic that relates to that. 

If you’re writing your college essay and they ask why you want to attend that school, you may want to have a main point and back it up with information, something along the lines of:

“Attending Harvard University would benefit me both academically and professionally, as it would give me a strong knowledge base upon which to build my career, develop my network, and hopefully give me an advantage in my chosen field.”

Step 3: Determine what information you’ll use to back up your point

Once you have the point you want to make, you need to figure out how you plan to back it up throughout the rest of your essay. Without this information, it will be hard to either prove or argue the main point of your thesis statement. If you decide to write about the Hamilton example, you may decide to address any falsehoods that the writer put into the musical, such as:

“The musical Hamilton, while accurate in many ways, leaves out key parts of American history, presents a nationalist view of founding fathers, and downplays the racism of the times.”

Once you’ve written your initial working thesis statement, you’ll then need to get information to back that up. For example, the musical completely leaves out Benjamin Franklin, portrays the founding fathers in a nationalist way that is too complimentary, and shows Hamilton as a staunch abolitionist despite the fact that his family likely did own slaves. 

Step 4: Revise and refine your thesis statement before you start writing

Read through your thesis statement several times before you begin to compose your full essay. You need to make sure the statement is ironclad, since it is the foundation of the entire paper. Edit it or have a peer review it for you to make sure everything makes sense and that you feel like you can truly write a paper on the topic. Once you’ve done that, you can then begin writing your paper.

When writing a thesis statement, there are some common pitfalls you should avoid so that your paper can be as solid as possible. Make sure you always edit the thesis statement before you do anything else. You also want to ensure that the thesis statement is clear and concise. Don’t make your reader hunt for your point. Finally, put your thesis statement at the end of the first paragraph and have your introduction flow toward that statement. Your reader will expect to find your statement in its traditional spot.

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you. CollegeVine offers a free peer essay review tool where one of your peers can read through your essay and provide you with valuable feedback. Getting essay feedback from a peer can help you wow your instructor or college admissions officer with an impactful essay that effectively illustrates your point.

Key Concepts

• A thesis is a simple sentence that combines your topic and your position on the topic.
• A thesis provides a roadmap to what follows in the paper.
• A thesis is like a wheel's hub--everything revolves around it and is attached to it.

After your prewriting activities-- such as assignment analysis and outlining--you should be ready to take the next step: writing a thesis statement. Although some of your assignments will provide a focus for you, it is still important for your college career and especially for your professional career to be able to state a satisfactory controlling idea or thesis that unifies your thoughts and materials for the reader.

Characteristics of an Effective Thesis

A thesis consists of two main parts: your overall topic and your position on that topic. Here are some example thesis statements that combine topic and position:

Sample Thesis Statements

Importance of tone.

Tone is established in the wording of your thesis, which should match the characteristics of your audience. For example, if you are a concerned citizen proposing a new law to your city's board of supervisors about drunk driving, you would not want to write this:

“It’s time to get the filthy drunks off the street and from behind the wheel: I demand that you pass a mandatory five-year license suspension for every drunk who gets caught driving. Do unto them before they do unto us!”

However, if you’re speaking at a concerned citizen’s meeting and you’re trying to rally voter support, such emotional language could help motivate your audience.

Using Your Thesis to Map Your Paper for the Reader

In academic writing, the thesis statement is often used to signal the paper's overall structure to the reader. An effective thesis allows the reader to predict what will be encountered in the support paragraphs. Here are some examples:

Use the Thesis to Map

Three potential problems to avoid.

Because your thesis is the hub of your essay, it has to be strong and effective. Here are three common pitfalls to avoid:

1. Don’t confuse an announcement with a thesis.

In an announcement, the writer declares personal intentions about the paper instead stating a thesis with clear point of view or position:

Write a Thesis, Not an Announcement

 2. a statement of fact does not provide a point of view and is not a thesis..

An introduction needs a strong, clear position statement. Without one, it will be hard for you to develop your paper with relevant arguments and evidence.

Don't Confuse a Fact with a Thesis

3. avoid overly broad thesis statements.

Broad statements contain vague, general terms that do not provide a clear focus for the essay.

Use the Thesis to Provide Focus

Practice writing an effective thesis.

OK. Time to write a thesis for your paper. What is your topic? What is your position on that topic? State both clearly in a thesis sentence that helps to map your response for the reader.

Developing Strong Thesis Statements

Welcome to the Purdue OWL

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

Thesis Characteristics

Whenever you are writing to explain something to your reader or to persuade your reader to agree with your opinion, there should be one complete sentence that expresses the main idea of your paper. That sentence is often called the thesis, or thesis statement. (Some other names it goes by are "the main idea" and "the controlling idea.") Based on everything you've read, and thought, and brainstormed, the thesis is not just your topic, but what you're saying about your topic. Another way to look at it is, once you've come up with the central question, or organizing question, of your essay, the thesis is an answer to that question. Remember, though, while you are still writing your paper, to consider what you have to be a "working thesis," one that may still be "adjusted." As you continue to write, read, and think about your topic, see if your working thesis still represents your opinion.

Handy reminders about the thesis (on this page): 

• Where to put it
• Put it as a statement
• Don't go overboard
• Focus further
• Choose the right shape

Where to Put the Thesis

The thesis usually comes within the introductory paragraph, which prepares the reader to listen to your ideas, and before the body of the paper, which develops the thesis with reasons, explanations, and evidence or examples. In fact, if you examine a well-written thesis, you will find hidden in it the questions your reader will expect you to answer in the body. For example, if your thesis is "Cannibalism, if practiced tastefully, can be acceptable in extreme circumstances," the body of your essay will develop this idea by explaining HOW it can be practiced tastefully, WHY it would be acceptable, and WHAT you would consider extreme circumstances.

Put the Thesis as a Statement

Make sure your thesis is in the form of a statement, not a question. "Can we save the Amazon rain forest?" is an ear-catching question that might be useful in the introduction, but it doesn't express an opinion or perspective as the following statements do:

• "We can save the Amazon rain forest by limiting tourist presence, boycotting goods made by companies that deplete the forest's resources, and generally educating people about the need to preserve the rain forest in order to preserve the earth's ecological systems."
• "We cannot save the Amazon rain forest since the companies that deplete its resources in their manufacturing are so widely-spread throughout the world, so politically powerful in their respective countries, and so wealthy that they are able to fight the opposition fully."

Don't go Overboard!

Make sure your thesis expresses your true opinion and not an exaggerated version of it. Don't say "Computers are wonderful" or "Computers are terrible" if what you really believe is "Computers do more good than harm" or "Computers do more harm than good." Why commit yourself to an extreme opinion that you don't really believe in, and then look like you're contradicting yourself later on?

Focus Further

Make sure your thesis covers exactly the topic you want to talk about, no more and no less. "Drugs should not be legalized" is too large a thesis if all you want to talk about is marijuana. "Boxing should be outlawed" is too small a thesis if you also want to discuss wrestling and football. Bite off as much as you can chew thoroughly--then chew it!

Choose the Right Shape

Shape your thesis to fit the question you wish to answer. A thesis can come in many forms, including the following:

• Simply stating an opinion: "Langston Hughes was a master stylist."
• Indicating categories or reasons: "Langston Hughes was a master stylist because of his vivid imagery, surprising metaphors, and effective alliteration."
• Showing two aspects of a topic and emphasizing one (in this sample, the 2nd topic in the sentence is emphasized): "While Langston Hughes was a master stylist, as a critic he had several blind spots."

Writing Resources

Features of a successful thesis.

This handout is available for download in DOCX format and PDF format .

• A thesis must consist of a claim. Questions are not claims; nor are simple descriptions. A thesis is not a topic or theme, either. It is a contention —something to be argued.
• A thesis should not be obviously true or false. If a claim is obviously true, there is no need to argue for it; and if is it obviously false, there is no reason to argue for it, either. Rather, the claim should be plausible, but in need of argument and evidence to establish its veracity.
• A thesis should not be overly abstract or general. It must be specific enough to be arguable, that is, specific enough to support with the evidence available to you.
• A thesis should be original. It should not merely recapitulate another writer’s argument. However, this does not mean that a thesis cannot be based on or influenced by the arguments of other writers.
• There must be evidence available to support the claim made in the thesis.
• The claim must be of an appropriate scope such that it can be adequately argued within the length of the paper.
• A thesis should be clear. Remove as much ambiguity as possible from your thesis statement, and define any technical or ambiguous terms (e.g., “Durkheim-Boas tradition,” “reductionism”) that appear in your thesis or essay.
• A thesis should be concise. Generally, a thesis will be contained within a single sentence, although sometimes more complex theses are developed over two or three sentences.
• A thesis should be obvious to your reader. Often, a thesis statement begins with a phrase like “I will argue…,” “In this essay I will contend…,” etc. Theses are often stated in the first paragraph or in introductory paragraphs.

Module 3: Definition Essay

Effective thesis statements, what is a thesis statement.

• A thesis statement tells a reader how you will interpret the significance of the subject matter under discussion. Such a statement is also called an “argument,” a “main idea,” or a “controlling idea.”
• A good thesis has two parts. It should tell what you plan to argue, and it should “telegraph” how you plan to argue—that is, what particular support for your claim is going where in your essay
• A standard place for your thesis is at the end of the introductory paragraph.
• A thesis is an interpretation of a subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel that others might dispute.
• A strong thesis not only grabs the interest of your reader, who now wants to see you support your unique interpretation, it also provides a focus for your argument, one to which every part of your paper refers in the development of your position.
• A thesis keeps the writer centered on the matter at hand and reduces the risk of intellectual wandering. Likewise, a thesis provides the reader with a “road map,” clearly laying out the intellectual route ahead.
• A thesis statement avoids the first person (“I believe,” “In my opinion”).

A simple equation for what a thesis might look like this:

What you plan to argue + How you plan to argue it = Thesis Specific Topic+ Attitude/Angle/Argument=Thesis

Steps To Write Effective Thesis Statement

• Choose a prompt or, if appropriate, select a topic: television violence and children
• What are the effects of television violence on children?
• Violence on television increases aggressive behavior in children.
• Avoid general phrasing and/or sweeping words such as “all” or “none” or “every”.
• Lead the reader toward the topic sentences (the subtopics needed to prove the thesis).
• While poor parenting and easy access to weapons may act as contributory factors, in fact when children are exposed to television violence they become less sensitive to the pain and suffering of others, are more fearful of the world around them, and are more likely to behave in aggressive or harmful ways toward others.

The Components of an Effective Thesis Statement

• You can’t just pluck a thesis out of thin air. Even if you have a terrific insight concerning a topic, it won’t be worth much unless you can logically and persuasively support it in the body of your essay. A thesis is the evolutionary result of a thinking process, not a miraculous creation. Formulating a thesis is not the first thing you do after reading an essay assignment .
• Substantial – Your thesis should be a claim for which it is easy to answer every reader’s question: “So what?”
• Supportable – A thesis must be a claim that you can prove with the evidence at hand (e.g., evidence from your texts or from your research). Your claim should not be outlandish, nor should it be mere personal opinion or preference (e.g., “Frederick Douglass is my favorite historical figure.”) It tackles a subject that could be adequately covered in the format of the project assigned.
• Precise – It is focused and specific. A strong thesis proves a point without discussing everything. It clearly asserts your own conclusion based on evidence. Note: Be flexible. It is perfectly okay to change your thesis!
• Arguable – It should be contestable, proposing an arguable point with which people could reasonably disagree.
• Relevant – If you are responding to an assignment, the thesis should answer the question your teacher has posed. In order to stay focused, pay attention to the task words in the assignment: summarize, argue, compare/contrast, etc.
• Aware of Counters – It anticipates and refutes the counter-arguments.

The best thesis statement is a balance of specific details and concise language. Your goal is to articulate an argument in detail without burdening the reader with too much information.

Questions To Review Your Thesis

• “Do I answer the question?” This might seem obvious, but it’s worth asking. No matter how intriguing or dazzling, a thesis that doesn’t answer the question is not a good thesis!
• “Have I taken a position that others might challenge or oppose?” If not, then you probably do not have a strong argument. Theses that are too vague often have this problem. If your thesis contains vague words like “good” or “successful,” see if you could be more specific: why is something “good”; what makes something “successful”?
• Would anyone possible care about this thesis? So What? Does your thesis present a position or an interpretation worth pursuing? If a reader’s first response is, “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• “Does my essay support my thesis specifically and without wandering?” Just as a thesis that doesn’t answer the question ultimately fails, so does a thesis that isn’t properly supported with evidence and reasoning.
• Does my thesis statement adequately address the direction words of the prompt: summarize, argue, compare/contrast, analyze, discuss, etc.?

Myths about Thesis Statements

• Every paper requires one . Assignments that ask you to write personal responses or to explore a subject don’t want you to seem to pre-judge the issues. Essays of literary interpretation often want you to be aware of many effects rather than seeming to box yourself into one view of the text.
• A thesis statement must come at the end of the first paragraph . This is a natural position for a statement of focus, but it’s not the only one. Some theses can be stated in the opening sentences of an essay; others need a paragraph or two of introduction; others can’t be fully formulated until the end.
• A thesis statement must be one sentence in length , no matter how many clauses it contains. Clear writing is more important than rules like these. Use two or three sentences if you need them. A complex argument may require a whole tightly-knit paragraph to make its initial statement of position.
• You can’t start writing an essay until you have a perfect thesis statement . It may be advisable to draft a hypothesis or tentative thesis statement near the start of a big project, but changing and refining a thesis is a main task of thinking your way through your ideas as you write a paper. And some essay projects need to explore the question in depth without being locked in before they can provide even a tentative answer.
• A thesis statement must give three points of support . It should indicate that the essay will explain and give evidence for its assertion, but points don’t need to come in any specific number.

Resources for Writers: Understanding an Assignment

Before you can successfully select a topic, you must understand exactly what the assignment requires.

Types of writing assignments vary from department to department, from course to course, and from instructor to instructor, so it is important to understand thoroughly the requirements of a particular assignment.

If the topic is not provided by the instructor

Sometimes instructors leave the selection of meaningful topics or research questions up to you. In such cases, you can find a topic by doing the following:

Begin by asking yourself why you were interested in this particular course in the first place. Your interest in the course might provide a clue about what to investigate.

• Look over class notes for provocative or interesting ideas.
• Focus on points from the notes that you find interesting or puzzling.
• Consider points about which the instructor has said “No one has adequately explained or explored X yet” or “It would be interesting to find out more about Y.”
• Consider the personal relevance this course might have for you.
• Ask yourself if you can test or expand a model or concept studied in class.
• Glance through books and journals in the area studied in class to find out what scholars are talking about and whether anything is missing from that scholarly conversation. If something is missing, that might be your topic.
• Ask your instructor or TA for suggestions.
• Explore some disagreement with a particular author or scholar in the field.
• If the topic is provided by the instructor.

If the assignment is explained but is not given to you in written form, remember that your instructors or TAs are the best source of information about their expectations for the assignment. In class or during office hours, ask questions and take notes about the key aspects of the assignment:

• the paper’s purpose
• the intended audience for the essay
• the amount of research required
• length requirements
• possible approaches

and the criteria used to grade your paper:

• originality of thought
• amount of research
• use of concepts

If the assignment is written out for you on the syllabus or on an assignment sheet, the following procedure should help.

1. Read the assignment more than once.

Highlight or underline key assignment words such as:

• argue (agree/disagree)
• compare and contrast

Such words tell you what kind of tasks your instructor expects you to perform.

Then highlight all other key technical terms that are course-specific or discipline-specific. Check these words in a good dictionary, even if you think you know what they mean. Some words have multiple meanings and special discipline-related meanings that you may not know.

2. Consider suggestions for topics given by the assignment itself.

Sometimes instructors structure topics or assignments to reflect one possible approach to the paper. Occasionally the assignment will tell you, directly or indirectly, what topics or aspects to consider and in what order. If your assignment does this, use the assignment to make a topic outline for your paper.

3. Consider which concepts or methods the assignment asks you to use.

Are you being asked to argue a point, to compare similarities and differences, or to explore your own reactions to an event, text, or idea? Does the topic ask you to go into depth about some material already covered? Does it ask you to evaluate a theory or model by applying it to a real-world example? Does it ask you to use research?

Essay assignments usually ask you to use the concepts, techniques, and ways of thinking that are featured in the course. Use these to ask yourself questions about the topics. Look also for controversies within the material studied.

4. Form a tentative thesis statement or central idea in the early stages of writing.

Having a thesis or hypothesis to support or prove will focus your thinking and help you say something significant. As you move through the writing process, you may discover that your thesis must be changed. That’s not an unusual occurrence.

5. Devise your own topic, if that’s allowed.

Some instructors are willing to let you create your own topic, rather than write on one of the suggested topics. If you have a topic you would like to explore, ask your instructor if you might substitute it for one of the suggested topics. If the instructor refuses your request, remember that there are probably several good pedagogical reasons for his/her wanting all the students working on the specific topics already assigned. Return to the steps above and select one of the topics that seems most promising to you. Remember, though, if you do suggest your own topic, make it at least as difficult and complex as the topic(s) suggested by the instructor.

Once you have analyzed the assignment, you are ready to begin the writing process.
