what are the three elements of thesis statement

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.

9.1 Developing a Strong, Clear Thesis Statement

Learning objectives.

• Develop a strong, clear thesis statement with the proper elements.
• Revise your thesis statement.

Have you ever known a person who was not very good at telling stories? You probably had trouble following his train of thought as he jumped around from point to point, either being too brief in places that needed further explanation or providing too many details on a meaningless element. Maybe he told the end of the story first, then moved to the beginning and later added details to the middle. His ideas were probably scattered, and the story did not flow very well. When the story was over, you probably had many questions.

Just as a personal anecdote can be a disorganized mess, an essay can fall into the same trap of being out of order and confusing. That is why writers need a thesis statement to provide a specific focus for their essay and to organize what they are about to discuss in the body.

Just like a topic sentence summarizes a single paragraph, the thesis statement summarizes an entire essay. It tells the reader the point you want to make in your essay, while the essay itself supports that point. It is like a signpost that signals the essay’s destination. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

Elements of a Thesis Statement

For every essay you write, you must focus on a central idea. This idea stems from a topic you have chosen or been assigned or from a question your teacher has asked. It is not enough merely to discuss a general topic or simply answer a question with a yes or no. You have to form a specific opinion, and then articulate that into a controlling idea —the main idea upon which you build your thesis.

Remember that a thesis is not the topic itself, but rather your interpretation of the question or subject. For whatever topic your professor gives you, you must ask yourself, “What do I want to say about it?” Asking and then answering this question is vital to forming a thesis that is precise, forceful and confident.

A thesis is one sentence long and appears toward the end of your introduction. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body. It forecasts the content of the essay and suggests how you will organize your information. Remember that a thesis statement does not summarize an issue but rather dissects it.

A Strong Thesis Statement

A strong thesis statement contains the following qualities.

Specificity. A thesis statement must concentrate on a specific area of a general topic. As you may recall, the creation of a thesis statement begins when you choose a broad subject and then narrow down its parts until you pinpoint a specific aspect of that topic. For example, health care is a broad topic, but a proper thesis statement would focus on a specific area of that topic, such as options for individuals without health care coverage.

Precision. A strong thesis statement must be precise enough to allow for a coherent argument and to remain focused on the topic. If the specific topic is options for individuals without health care coverage, then your precise thesis statement must make an exact claim about it, such as that limited options exist for those who are uninsured by their employers. You must further pinpoint what you are going to discuss regarding these limited effects, such as whom they affect and what the cause is.

Ability to be argued. A thesis statement must present a relevant and specific argument. A factual statement often is not considered arguable. Be sure your thesis statement contains a point of view that can be supported with evidence.

Ability to be demonstrated. For any claim you make in your thesis, you must be able to provide reasons and examples for your opinion. You can rely on personal observations in order to do this, or you can consult outside sources to demonstrate that what you assert is valid. A worthy argument is backed by examples and details.

Forcefulness. A thesis statement that is forceful shows readers that you are, in fact, making an argument. The tone is assertive and takes a stance that others might oppose.

Confidence. In addition to using force in your thesis statement, you must also use confidence in your claim. Phrases such as I feel or I believe actually weaken the readers’ sense of your confidence because these phrases imply that you are the only person who feels the way you do. In other words, your stance has insufficient backing. Taking an authoritative stance on the matter persuades your readers to have faith in your argument and open their minds to what you have to say.

Even in a personal essay that allows the use of first person, your thesis should not contain phrases such as in my opinion or I believe . These statements reduce your credibility and weaken your argument. Your opinion is more convincing when you use a firm attitude.

On a separate sheet of paper, write a thesis statement for each of the following topics. Remember to make each statement specific, precise, demonstrable, forceful and confident.

• Texting while driving
• The legal drinking age in the United States
• Steroid use among professional athletes

Examples of Appropriate Thesis Statements

Each of the following thesis statements meets several of the following requirements:

• Specificity
• Ability to be argued
• Ability to be demonstrated
• Forcefulness
• The societal and personal struggles of Troy Maxon in the play Fences symbolize the challenge of black males who lived through segregation and integration in the United States.
• Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
• Shakespeare’s use of dramatic irony in Romeo and Juliet spoils the outcome for the audience and weakens the plot.
• J. D. Salinger’s character in Catcher in the Rye , Holden Caulfield, is a confused rebel who voices his disgust with phonies, yet in an effort to protect himself, he acts like a phony on many occasions.
• Compared to an absolute divorce, no-fault divorce is less expensive, promotes fairer settlements, and reflects a more realistic view of the causes for marital breakdown.
• Exposing children from an early age to the dangers of drug abuse is a sure method of preventing future drug addicts.
• In today’s crumbling job market, a high school diploma is not significant enough education to land a stable, lucrative job.

You can find thesis statements in many places, such as in the news; in the opinions of friends, coworkers or teachers; and even in songs you hear on the radio. Become aware of thesis statements in everyday life by paying attention to people’s opinions and their reasons for those opinions. Pay attention to your own everyday thesis statements as well, as these can become material for future essays.

Now that you have read about the contents of a good thesis statement and have seen examples, take a look at the pitfalls to avoid when composing your own thesis:

A thesis is weak when it is simply a declaration of your subject or a description of what you will discuss in your essay.

Weak thesis statement: My paper will explain why imagination is more important than knowledge.

A thesis is weak when it makes an unreasonable or outrageous claim or insults the opposing side.

Weak thesis statement: Religious radicals across America are trying to legislate their Puritanical beliefs by banning required high school books.

A thesis is weak when it contains an obvious fact or something that no one can disagree with or provides a dead end.

Weak thesis statement: Advertising companies use sex to sell their products.

A thesis is weak when the statement is too broad.

Weak thesis statement: The life of Abraham Lincoln was long and challenging.

Read the following thesis statements. On a separate piece of paper, identify each as weak or strong. For those that are weak, list the reasons why. Then revise the weak statements so that they conform to the requirements of a strong thesis.

• The subject of this paper is my experience with ferrets as pets.
• The government must expand its funding for research on renewable energy resources in order to prepare for the impending end of oil.
• Edgar Allan Poe was a poet who lived in Baltimore during the nineteenth century.
• In this essay, I will give you lots of reasons why slot machines should not be legalized in Baltimore.
• Despite his promises during his campaign, President Kennedy took few executive measures to support civil rights legislation.
• Because many children’s toys have potential safety hazards that could lead to injury, it is clear that not all children’s toys are safe.
• My experience with young children has taught me that I want to be a disciplinary parent because I believe that a child without discipline can be a parent’s worst nightmare.

Writing at Work

Often in your career, you will need to ask your boss for something through an e-mail. Just as a thesis statement organizes an essay, it can also organize your e-mail request. While your e-mail will be shorter than an essay, using a thesis statement in your first paragraph quickly lets your boss know what you are asking for, why it is necessary, and what the benefits are. In short body paragraphs, you can provide the essential information needed to expand upon your request.

Thesis Statement Revision

Your thesis will probably change as you write, so you will need to modify it to reflect exactly what you have discussed in your essay. Remember from Chapter 8 “The Writing Process: How Do I Begin?” that your thesis statement begins as a working thesis statement , an indefinite statement that you make about your topic early in the writing process for the purpose of planning and guiding your writing.

Working thesis statements often become stronger as you gather information and form new opinions and reasons for those opinions. Revision helps you strengthen your thesis so that it matches what you have expressed in the body of the paper.

The best way to revise your thesis statement is to ask questions about it and then examine the answers to those questions. By challenging your own ideas and forming definite reasons for those ideas, you grow closer to a more precise point of view, which you can then incorporate into your thesis statement.

Ways to Revise Your Thesis

You can cut down on irrelevant aspects and revise your thesis by taking the following steps:

1. Pinpoint and replace all nonspecific words, such as people , everything , society , or life , with more precise words in order to reduce any vagueness.

Working thesis: Young people have to work hard to succeed in life.

Revised thesis: Recent college graduates must have discipline and persistence in order to find and maintain a stable job in which they can use and be appreciated for their talents.

The revised thesis makes a more specific statement about success and what it means to work hard. The original includes too broad a range of people and does not define exactly what success entails. By replacing those general words like people and work hard , the writer can better focus his or her research and gain more direction in his or her writing.

2. Clarify ideas that need explanation by asking yourself questions that narrow your thesis.

Working thesis: The welfare system is a joke.

Revised thesis: The welfare system keeps a socioeconomic class from gaining employment by alluring members of that class with unearned income, instead of programs to improve their education and skill sets.

A joke means many things to many people. Readers bring all sorts of backgrounds and perspectives to the reading process and would need clarification for a word so vague. This expression may also be too informal for the selected audience. By asking questions, the writer can devise a more precise and appropriate explanation for joke . The writer should ask himself or herself questions similar to the 5WH questions. (See Chapter 8 “The Writing Process: How Do I Begin?” for more information on the 5WH questions.) By incorporating the answers to these questions into a thesis statement, the writer more accurately defines his or her stance, which will better guide the writing of the essay.

3. Replace any linking verbs with action verbs. Linking verbs are forms of the verb to be , a verb that simply states that a situation exists.

Working thesis: Kansas City schoolteachers are not paid enough.

Revised thesis: The Kansas City legislature cannot afford to pay its educators, resulting in job cuts and resignations in a district that sorely needs highly qualified and dedicated teachers.

The linking verb in this working thesis statement is the word are . Linking verbs often make thesis statements weak because they do not express action. Rather, they connect words and phrases to the second half of the sentence. Readers might wonder, “Why are they not paid enough?” But this statement does not compel them to ask many more questions. The writer should ask himself or herself questions in order to replace the linking verb with an action verb, thus forming a stronger thesis statement, one that takes a more definitive stance on the issue:

• Who is not paying the teachers enough?
• What is considered “enough”?
• What is the problem?
• What are the results

4. Omit any general claims that are hard to support.

Working thesis: Today’s teenage girls are too sexualized.

Revised thesis: Teenage girls who are captivated by the sexual images on MTV are conditioned to believe that a woman’s worth depends on her sensuality, a feeling that harms their self-esteem and behavior.

It is true that some young women in today’s society are more sexualized than in the past, but that is not true for all girls. Many girls have strict parents, dress appropriately, and do not engage in sexual activity while in middle school and high school. The writer of this thesis should ask the following questions:

• Which teenage girls?
• What constitutes “too” sexualized?
• Why are they behaving that way?
• Where does this behavior show up?
• What are the repercussions?

In the first section of Chapter 8 “The Writing Process: How Do I Begin?” , you determined your purpose for writing and your audience. You then completed a freewriting exercise about an event you recently experienced and chose a general topic to write about. Using that general topic, you then narrowed it down by answering the 5WH questions. After you answered these questions, you chose one of the three methods of prewriting and gathered possible supporting points for your working thesis statement.

Now, on a separate sheet of paper, write down your working thesis statement. Identify any weaknesses in this sentence and revise the statement to reflect the elements of a strong thesis statement. Make sure it is specific, precise, arguable, demonstrable, forceful, and confident.

Collaboration

Please share with a classmate and compare your answers.

In your career you may have to write a project proposal that focuses on a particular problem in your company, such as reinforcing the tardiness policy. The proposal would aim to fix the problem; using a thesis statement would clearly state the boundaries of the problem and tell the goals of the project. After writing the proposal, you may find that the thesis needs revision to reflect exactly what is expressed in the body. Using the techniques from this chapter would apply to revising that thesis.

Key Takeaways

• Proper essays require a thesis statement to provide a specific focus and suggest how the essay will be organized.
• A thesis statement is your interpretation of the subject, not the topic itself.
• A strong thesis is specific, precise, forceful, confident, and is able to be demonstrated.
• A strong thesis challenges readers with a point of view that can be debated and can be supported with evidence.
• A weak thesis is simply a declaration of your topic or contains an obvious fact that cannot be argued.
• Depending on your topic, it may or may not be appropriate to use first person point of view.
• Revise your thesis by ensuring all words are specific, all ideas are exact, and all verbs express action.

How to write a thesis statement + examples

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

• Condense the main idea of your thesis into one or two sentences.
• Answer your project’s main research question.
• Clearly state your position in relation to the topic .
• Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

• Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
• Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
• Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

• The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

What Is a Thesis? | Ultimate Guide & Examples

Published on September 14, 2022 by Tegan George . Revised on November 21, 2023.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a master’s program or a capstone to a bachelor’s degree.

Writing a thesis can be a daunting experience. Other than a dissertation , it is one of the longest pieces of writing students typically complete. It relies on your ability to conduct research from start to finish: choosing a relevant topic , crafting a proposal , designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.
• In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
• Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Professional editors proofread and edit your paper by focusing on:

• Vague sentences
• Style consistency

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

Read more about tables of contents

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the “Insert Caption” feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

Read more about glossaries

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

What are the common elements of a thesis statement?

This is the second of three chapters about Thesis Statements . To complete this short reader, read each chapter carefully and then unlock and complete our materials to check your understanding.   

– Introduce the concept of thesis statement elements

– Explore the four different thesis-statement elements

– Provide examples to help guide and inform the reader

Chapter 1: What are thesis statements and why are they important?

Chapter 2: What are the common elements of a thesis statement?

Before you begin reading...

• video and audio texts
• knowledge checks and quizzes
• skills practices, tasks and assignments

Now that we’ve discussed what a thesis statement is and why it’s important to include one in the introduction of an academic assignment , this chapter next focuses on exploring the elements of two example thesis statements. Once students have a good understanding of the mandatory and optional elements of a thesis statement, it should become a fairly easy process to change the variables of a thesis and rebuild their statements in a similar and accurate way each time.

1. Task Language and Task Type

The first two elements that all thesis statements should possess is some use of task language and some mention of the task type. The language provided below works to inform the reader both of the format of the essay as well as the particular essay type – and any experienced reader will then be able to (based on this type) predict the likely structure of the content. In combination, task language and task type create what is known as a ‘purpose statement’.

2. Topic and Arguments

While the purpose statement may be fairly formulaic, the majority of a thesis statement is composed of the essay topic (often created from the essay question) and the writer’s key arguments (also known as main ideas). With an inclusion of the previously mentioned purpose statement, the following table deconstructs our first thesis statement example (for an informative essay) into its key components. 

Sometimes, however, and particularly with persuasive essays , a student may be required to provide both arguments and counter arguments. Such a structure can be seen in the table below, which uses our second thesis-statement example:

Another aspect that’s often required when writing persuasively such as in an evaluative essay is the inclusion of the writer’s stance . In short, stance is the author’s opinion about the overall argument of the essay. Does the writer, for example, agree or disagree with the essay question? When writing persuasively, such stance should usually be clear and apparent in an essay’s thesis statement and restatement , as well as in the body paragraph topic sentences . The figures below indicate the stance that exists in both of our example thesis statements:

4. Outlines

One final element of a thesis statement that should generally be included in an academic essay  is what’s known as the outline (or roadmap). An outline is intended to inform the reader of (1) the essay’s key arguments ( main ideas ), and (2) the order in which those arguments will appear in the essay. We’ve provided our two example thesis statements for you below with each main idea underlined:

From these thesis statement outlines, the reader can presume the following essay structure if this were a five-paragraph essay. However, please note that there may in reality be some variation between the outline and the essay structure as the writer may decide to combine two main ideas into one body paragraph , perhaps including also a paragraph of counter argument.

Having now discussed the four key elements of a thesis statement, the final chapter of this topic provides examples, tips and advice for how to write effective thesis statements every time.

A strong component of academic writing that all writers must understand is the difference between subject, topic, and thesis. Knowing the difference between these three terms will help you create a strong argument for your paper. This handout is designed to help inform you about these three distinct introductory elements, and it will also help you transition from deciding on a subject you are writing about, to the essay’s topic, and finally to your overall thesis.

The subject of your paper is a broad idea that stands alone. At this point, there is no detailed information associated with it or any kind of argumentation. It serves, in essence, as a launching pad for you to form an idea, or argument, which will eventually become the purpose of your paper.

Example: Women

The topic of your paper is an evolved, narrower version of your subject. Here is where you add a detailed, more conclusive area of focus for your paper so that you can eradicate vagueness.

Example: Women in late 1990s television

The thesis acts as the final idea on which the entirety of your paper will focus. It is the central message that ties the whole paper together into one definitive purpose that prepares readers for what you are arguing.

Example : Although people may argue that television in the late 1990s helped portray women in a more honest and intrepid light, programs including Buffy the Vampire Slayer, Charmed , and Sex and the City failed to illustrate the depth and truth of womanhood, choosing to focus heavily on clichéd romantic entanglements, unbecoming pathetic quarrels, and thin temptresses adorned with fashionable costumes and bare midriffs.

Subject to Topic

The following are some suggestions to help you shift from a broad subject area to a narrow, focused topic.

Seek out narrow topics

Inappropriate.

Subject:  Women

Topic:  Women in history

Note:  In this case, the topic is too large to create a complex thesis statement worthy of a paper. The broader the topic, the more difficulty you will have narrowing your argument enough to affect readers.

Appropriate

Topic:  Famous women aviators of WWII

Note:  Here the topic as narrowed down the subject by focusing on women belonging to a specific profession in a particular historical period. It is thorough enough to discover a thesis statement.

Choose arguable topics

Subject:  Toni Morrison

Topic:  Biography

Note:  This idea does not allow for speculation or disagreement, which gives it an underdeveloped quality.

Topic:  Literary merits of the novel Tar Baby

Note:  This idea allows for speculation or disagreement, which gives it a strong, developed quality.

Choose topics within your comfort zone

Subject:  Linguistics

Topic:  OE Northumbrian dialects

Note:  Unless you have studied OE Northumbrian dialects at length, it perhaps poses too high of a research challenge to pursue.

Subject:  College Freshmen

Topic:  The Freshman Fifteen

Note:  This topic is narrow enough and familiar enough to most college students to purse as a topic.

Rules for Thesis Statements

• Needs to correspond to the assignment’s expectations
• Usually, but not always, one sentence
• Typically appears that the end of the introduction
• More often than not, it is explicitly stated
• Establishes an argument
• Establishes the criteria for scrutiny of the topic (previews the structure of the paper)
• Write for an audience. Your paper should be catchy enough to retain readers’ attention.

Determine a "Research Question"

Determining a research question is a crucial aspect of your writing. In order to stay focused on the assignment, you must form a clear and concise argument. Choose one major idea you want to concentrate on, and expand from there.

When your instructor assigns a paper, try and find some angle that makes you inspired to fulfill the assignment to the best of your abilities. For example, if your history professor assigns you to write about a historical figure who changed the world for the better, write about an individual whose work you can relate to. If you are interested in the supernatural, you could write about Joan of Arc, who became a crusader because of the visions she claimed to have had from God.

Next, ask yourself a series of questions to help form your research question. Try to avoid questions you can answer with “yes” or “no” because these will not allow you to explore your topic as thoroughly or as easily as questions that begin with “who,” “what,” “why,” or “how.”

• When did Joan rise to prominence?
• Did she develop a strong following that her enemies felt threatened by?
• How did her gender play a part in her tragic demise?
• What does Joan’s execution say about female leaders of the 15th century?

Once you have developed a series of questions, consider which questions allow you to form an argument that is not too broad that you cannot write a sufficient paper, but not too narrow that it prevents you from crafting an interesting and compelling piece of writing. Decide which question represents this criteria, then you can start researching. In this case, from the above examples, you may select “How did Joan’s gender play a part in her tragic demise?” This question will allow you to develop a complex thesis with argumentative points to pose to readers. Below is a way to develop a thesis statement from the simply worded question that was just brainstormed.

The answer to your research question can become the core of your thesis statement.

Research Question:

How did Joan of Arc’s gender play a part in her tragic demise?

Thesis Statement:

Joan of Arc’s gender played a significant role in her tragic demise because of the laws and social customs concerning women during France’s 15th century, which included social ideals that perceived women as secular citizens; political standards that favored men to hold positions of power over women; as well as religious ideals that perceived Joan’s alleged clairvoyant gifts as a natural trait of witchcraft, a crime of heresy also associated with women.

Note:  Beginning writers are taught to write theses that list and outline the main points of the paper. As college students, professors might expect more descriptive theses. Doing this will illustrate two points: 1) Readers will be able to isolate your argument, which will keep them more inclined to focus on your points and whether or not they agree with you. They may find themselves questioning their own thoughts about your case. 2) A descriptive thesis serves as a way to show your understanding of the topic by providing a substantial claim.

Troubleshooting your Thesis Statement

The following are some suggestions to help you scrutinize your working draft of your thesis statement to develop it through further revisions.

Specify your details

Example:  In today’s society, beauty advertisements are not mere pictures that promote vanity in the public, but instead, they inspire people to make changes so that they can lead better lifestyles.

• Uses cliché phrases like “In today’s society.”
• What kind of beauty advertisements are you referring to? All of them? Or specific kinds?

Note:  Who is this targeting? Women? Men? Adolescents? Being more specific with the targeted audience is going to strengthen your paper.

Example:  Makeup, clothing, and dieting advertisements endorse American ideals of female beauty and show the public that women should possess full ownership of their bodies and fight the stigma of physical and sexual repression which has been placed upon them.

• Identifies specific forms of beauty advertisements for the sake of clearly expressing a strong argument.
• Uses descriptive language.

Note:  By signifying that women’s beauty is the main topic being argued in the paper, this author clearly identifies their main, targeted audience.

Make arguable claims

Undeveloped.

Example:  Social media is not conducive to people’s personal growth because of the distractions, self-doubt, and social anxiety it can cause to its users.

• “Social media” and “personal growth” both encompass a large span of topics and so they leave the reader confused about the particular focus of this paper.

Note:  The thesis is too broad to form a well-constructed argument. It lacks details and specificity about the paper’s points.

Example:  Although Facebook allows people to network personally and professionally, the procrastination and distraction from one’s demanding responsibilities can lead people to invest more time in narcissistic trivialities, resulting in severe cases of anxiety and low self-esteem.

• It alludes to some kind of counterargument in the opening dependent clause.
• The thesis specifies several points that makes a thesis credible. The argument connects all the points (distractions, self-doubt, and social anxiety) together into one linear train of thought, relating the ideas to one another.

Note:  The thesis is more focused. It concentrates on the idea that social media plays up on a person’s self-worth.

Preview the paper’s structure

Example:  College is a crucial stage in one’s life that will help them become more sophisticated individuals upon entering the harsh world as an adult.

Note:  Not only does this statement lack specificity and excitement, but it fails to present an idea of what the paper will look like, and how the argument is set up. As readers, we know this writer believes college is an imperative part of one’s life, but we have no idea how they are going to go about arguing that claim.

Example:  College is a crucial stage in a young adult’s life because it is the time in which they begin to transition from childhood to adulthood, learn to live away from their parents, budget their own finances, and take responsibility for their successes and failures, which will force them to make more responsible decisions about their lives.

Note:  The thesis points to different aspects of college life that help students ease into adulthood, which shows the reader the points the writer will explore throughout the body of the paper.

• transition from childhood to adulthood
• learn to live away from their parents
• budget their own finances
• take responsibility for their successes and failures

Final Thoughts

When you are asked to write a paper in college, there may not be as many detailed descriptions telling you what subject or argument to write about. Remember, the best way to pick your subject is to write about something that interests you. That way, the assignment will be more promising and passionate for you and may help you feel more in control of your writing.

As you venture closer to crafting your thesis, make sure your subject is narrowed down to a specific enough topic so that you can stay focused on the task. If your topic is specific enough, you will be able to create an argument that is concentrated enough for you to provide sufficient argumentative points and commentary.

Chapter 5: Putting the Pieces Together with a Thesis Statement

5.2 Developing a Strong, Clear Thesis Statement

Learning Objectives

• Develop a strong, clear thesis statement with the proper elements
• Revise your thesis statement

Have you ever known someone who was not very good at telling stories? You probably had trouble following the train of thought as the storyteller jumped from point to point, either being too brief in places that needed further explanation or providing too many details on a meaningless element. Maybe the person told the end of the story first, then moved to the beginning and later added details to the middle. The ideas were probably scattered, and the story did not flow very well. When the story was over, you probably had many questions.

Just as a personal anecdote can be a disorganized mess, an essay can fall into the same trap of being out of order and confusing. That is why writers need a thesis statement  to provide a specific focus for their essay and to organize what they are about to discuss in the body.

Just like a topic sentence summarizes a single paragraph, the thesis statement summarizes an entire essay. It tells the reader the point you want to make in your essay, while the essay itself supports that point. It is like a signpost that signals the essay’s destination. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

Elements of a Thesis Statement

For every essay you write, you must focus on a central idea. This idea stems from a topic you have chosen or been assigned or from a question your teacher has asked. It is not enough merely to discuss a general topic or simply answer a question with a yes or no. You have to form a specific opinion, and then articulate that into a  controlling idea —the main idea upon which you build your thesis.

Remember that a thesis is not the topic itself, but rather your interpretation of the question or subject. For whatever topic your instructor gives you, you must ask yourself, “What do I want to say about it?” Asking and then answering this question is vital to forming a thesis that is precise, forceful, and confident.

A thesis is one sentence long and appears toward the end of your introduction. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body. It forecasts the content of the essay and suggests how you will organize your information. Remember that a thesis statement does not summarize an issue but rather dissects it.

A Strong Thesis Statement

A strong thesis statement contains the following qualities:

Specificity: A thesis statement must concentrate on a specific area of a general topic. As you may recall, the creation of a thesis statement begins when you choose a broad subject and then narrow down its parts until you pinpoint a specific aspect of that topic. For example, health care is a broad topic, but a proper thesis statement would focus on a specific area of that topic, such as options for individuals without health care coverage.

Precision: A strong thesis statement must be precise enough to allow for a coherent argument and to remain focused on the topic. If the specific topic is options for individuals without health care coverage, then your precise thesis statement must make an exact claim about it, such as that limited options exist for those who are uninsured by their employers. You must further pinpoint what you are going to discuss regarding these limited effects, such as whom they affect and what the cause is.

Arguability: A thesis statement must present a relevant and specific argument. A factual statement often is not considered arguable. Be sure your thesis statement contains a point of view that can be supported with evidence.

Demonstrability: For any claim you make in your thesis, you must be able to provide reasons and examples for your opinion. You can rely on personal observations in order to do this, or you can consult outside sources to demonstrate that what you assert is valid. A worthy argument is backed by examples and details.

Forcefulness/Assertiveness: A thesis statement that is forceful shows readers that you are, in fact, making an argument. The tone is assertive and takes a stance that others might oppose.

Confidence: In addition to using force in your thesis statement, you must also use confidence in your claim. Phrases such as I feel or I believe actually weaken the readers’ sense of your confidence because these phrases imply that you are the only person who feels the way you do. In other words, your stance has insufficient backing. Taking an authoritative stance on the matter persuades your readers to have faith in your argument and open their minds to what you have to say.

Self-Practice Exercise 5.4

H5P: Drafting Thesis StatementsWrite a clear, confident thesis statement for an essay on the following topic:

• Texting while driving.
• The legal drinking age in different provinces of Canada.
• Steroid use among professional athletes.

Examples of Appropriate Thesis Statements

Each of the following thesis statements meets several of the qualities discussed above: specificity, precision, arguability, demonstrability, forcefulness/assertiveness, and confidence.

• The societal and personal struggles of Floyd in the play Where the Blood Mixes, by Kevin Loring, symbolize the challenge of First Nations people of Canada who lived through segregation and placement into residential schools.
• Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
• Shakespeare’s use of dramatic irony in Romeo and Juliet spoils the outcome for the audience and weakens the plot.
• J. D. Salinger’s character in Catcher in the Rye, Holden Caulfield, is a confused rebel who voices his disgust with phonies, yet in an effort to protect himself, he acts like a phony on many occasions.
• Compared to an absolute divorce, no-fault divorce is less expensive, promotes fairer settlements, and reflects a more realistic view of the causes for marital breakdown.
• Exposing children from an early age to the dangers of drug abuse is a sure method of preventing future drug addicts.
• In today’s crumbling job market, a high school diploma is not significant enough education to land a stable, lucrative job.

Now that you have read about the contents of a good thesis statement and have seen examples, take a look four pitfalls to avoid when composing your own thesis.

• A thesis is weak when it is simply a declaration of your subject or a description of what you will discuss in your essay. Weak thesis statement: My paper will explain why imagination is more important than knowledge.
• A thesis is weak when it makes an unreasonable or outrageous claim or insults the opposing side. Weak thesis statement: Religious radicals across the country are trying to legislate their puritanical beliefs by banning required high school books.
• A thesis is weak when it contains an obvious fact or something that no one can disagree with or provides a dead end. Weak thesis statement: Advertising companies use sex to sell their products.
• A thesis is weak when the statement is too broad. Weak thesis statement :  The life of Pierre Trudeau was long and accomplished.

Self-Practice Exercise 5.5

H5P: Read the following thesis statements and identify each as weak or strong.

• “The subject of this paper is my experience with ferrets as pets.”
• “The government must expand its funding for research on renewable energy resources in order to prepare for the impending end of oil.”
• “Edgar Allan Poe was a poet who lived in Baltimore during the 19th century.”
• “In this essay, I will give you a lot of reasons why marijuana should not be legalized in British Columbia.”
• “Because many children’s toys have potential safety hazards that could lead to injury, it is clear that not all children’s toys are safe.”
• “My experience with young children has taught me that I want to be a disciplinary parent because I believe that a child without discipline can be a parent’s worst nightmare.”

Writing at Work

Often in your career, you will need to ask your boss for something through an email. Just as a thesis statement organizes an essay, it can also organize your email request. While your email will be shorter than an essay, using a thesis statement in your first paragraph quickly lets your boss know what you are asking for, why it is necessary, and what the benefits are. In short body paragraphs, you can provide the essential information needed to expand upon your request.

Writing a Thesis Statement

One legitimate question readers always ask about a piece of writing is “What is the big idea?” (You may even ask this question when you are the reader, critically reading an assignment or another document.) Every nonfiction writing task—from the short essay to the 10-page term paper to the lengthy senior thesis—needs a big idea, or a controlling idea, as the “spine” for the work. The controlling idea is the main idea that you want to present and develop.

The big idea, or controlling idea, you want to present in an essay is expressed in your thesis statement. Remember that a thesis statement is often one sentence long, and it states your point of view. The thesis statement is not the topic of the piece of writing but rather what you have to say about that topic and what is important to tell readers.

Look at Table 5.1: Topics and Thesis Statements  for a comparison of topics and thesis statements.

The first thesis statement you write will be a preliminary thesis statement , or a working thesis statement . You will need it when you begin to outline your assignment as a way to organize it. As you continue to develop the arrangement, you can limit your working thesis statement if it is too broad or expand it if it proves too narrow for what you want to say.

Self-Practice Exercise 5.6

H5P: Working Toward a Working Thesis

We’re going to use that free writing strategy again. This time, try to write for ten minutes, and write down anything you know right now about your newly narrowed thesis statement. Don’t worry about looking material up or whether you’re getting everything exactly right. Instead, just focus on getting words on the screen. This is rough work to help you approach an answer to a question, not the final essay. So just keep writing.

Can you find something in your freewriting that looks like a “controlling idea”? Something that might centre your argument, something you can structure your argument around? We’ll call that your working thesis. Draft a working thesis below.

Collaboration: Please share with a classmate and compare your answers.

Revising a Thesis Statement

Your thesis will probably change as you write, so you will need to modify it to reflect exactly what you have discussed in your essay. Remember, you begin with a working thesis statement, an indefinite statement that you make about your topic early in the writing process for the purpose of planning and guiding your writing.

Working thesis statements often become stronger as you gather information and form new opinions and reasons for those opinions. Revision helps you strengthen your thesis so that it matches what you have expressed in the body of the paper.

You can cut down on irrelevant aspects and revise your thesis by taking the following steps:

• Working thesis: Young people have to work hard to succeed in life.
• Revised thesis: Recent college graduates must have discipline and persistence in order to find and maintain a stable job in which they can use and be appreciated for their talents.
• Working thesis: The welfare system is a joke.
• Revised thesis: The welfare system keeps a socioeconomic class from gaining employment by alluring members of that class with unearned income, instead of programs to improve their education and skill sets.
• Working thesis: British Columbian schoolteachers are not paid enough.
• Revised thesis: The legislature of British Columbia cannot afford to pay its educators, resulting in job cuts and resignations in a district that sorely needs highly qualified and dedicated teachers.

The linking verb in this working thesis statement is the word are. Linking verbs often make thesis statements weak because they do not express action. Reading the original thesis statement above, readers might wonder why teachers are not paid enough, but the statement does not compel them to ask many more questions. The writer should ask him- or herself questions in order to replace the linking verb with an action verb, thus forming a stronger thesis statement, one that takes a more definitive stance on the issue. For example, the writer could ask:

• Who is not paying the teachers enough?
• What is considered “enough”?
• What is the problem?
• What are the results
• Working thesis: Today’s teenage girls are too sexualized.
• Which teenage girls?
• What constitutes “too” sexualized?
• Why are they behaving that way?
• Where does this behaviour show up?
• What are the repercussions?

Self-practice exercise  5.7

H5P:  Polishing the Thesis Statement

A working thesis statement is always a work in progress, and we make it stronger by asking questions of it and challenging the first draft. That’s the next job you have! It takes many revisions to make your work the best it can be, so try not to get frustrated by the process.

• Copy your working thesis statement for reference here.
• Pinpoint and replace all nonspecific words, such as people, everything, society, or life, with more precise words in order to reduce any vagueness. Recopy the newly revised thesis below.
• Replace any linking verbs with action verbs. Linking verbs gives information about the subject, such as a condition or relationship (is, appear, smell, sound), but they do not show any action. The most common linking verb is any forms of the verb to be, a verb that simply states that a situation exists. Recopy the newly revised thesis below.
• Omit any general claims that are hard to support. Recopy the newly revised thesis below.

Just Asking Questions

Clarify ideas that need explanation by asking yourself questions that narrow your thesis. The most straightforward way to do this is to ask yourself the 5WHs again — who, what, where, when, why, and how — and see were you can make your thesis statement more specific. List the questions you have about your own thesis below.

Now do your best to answer those questions.

And finally, revise your thesis in relation to these points and share it below.

In your career you may have to write a project proposal that focuses on a particular problem in your company, such as reinforcing the tardiness policy. The proposal would aim to fix the problem; using a thesis statement would clearly state the boundaries of the problem and the goals of the project. After writing the proposal, you may find that the thesis needs revising to reflect exactly what is expressed in the body. The techniques from this chapter would apply to revising that thesis.

Key Takeaways

• Proper essays require a thesis statement to provide a specific focus and suggest how the essay will be organized.
• A thesis statement is your interpretation of the subject, not the topic itself.
• A strong thesis is specific, precise, forceful, confident, and is able to be demonstrated.
• A strong thesis challenges readers with a point of view that can be debated and supported with evidence.
• A weak thesis is simply a declaration of your topic or contains an obvious fact that cannot be argued.
• Depending on your topic, it may or may not be appropriate to use first person point of view.
• Revise your thesis by ensuring all words are specific, all ideas are exact, and all verbs express action.

Writing a Thesis Statement — Definition, Types, and Examples

What is a thesis statement?

A thesis statement is a single sentence that identifies the topic and purpose of a scholarly research paper or academic writing. A thesis statement directly or indirectly presents the main points of the paper. Information presented in the essay should tie directly back to the thesis.

Overall, a good thesis statement accomplishes the following:

Identifies the purpose of the essay

Expresses the writer's position/opinion

Lists the main supports (optional)

Briefly summarizes the writer's conclusion(s)

Establish if the essay is explanatory, argumentative, or analytical

People often confuse thesis statements with topic sentences , which start each body paragraph. Typically, the thesis statement is the final sentence in the introductory paragraph and acts as a “road map” for the rest of the paper.

Types of thesis statements

The three main types of thesis statements are explanatory, argumentative, and analytical.

Explanatory thesis statements are used in expository essays that focus solely on informing the reader. Papers with this type of thesis do not contain the writer's opinion, nor do they try to persuade the reader.

The three main branches of science taught in public schools include biology, chemistry, and physics.

Argumentative thesis statements identify the writer's position or point of view on a given topic. Argumentative essays persuade the reader to agree with the writer's stance. If the reader cannot agree or disagree with the claim in the thesis, then it is not argumentative.

Public schools should place more emphasis on the arts because they encourage creativity, help improve academic development, and provide a beneficial emotional outlet.

Analytical thesis statements are used in papers that analyze how or why something does what it does. These thesis statements identify what the writer is analyzing, the parts of the analysis, and the order of those parts.

An analysis of course requirements in public schools suggests access to more electives can increase graduation rates.

How to write a thesis statement

When writing a thesis, the following guidelines apply:

Step 1: Determine the type of paper (explanatory, argumentative, or analytical).

Step 2: Identify the topic, position/claim, and supports of the essay.

Step 3: Determine if the supports should be included within the thesis. Although they are considered optional, they might be required depending on the audience and purpose of the essay.

Step 4: Compose a sentence that includes the topic, position, and supports (optional). While a thesis statement can be more than one sentence, it should not exceed two.

Step 5: Place the thesis statement at the end of the introductory paragraph(s). Placing it at the end of the introduction and before the supports allows the reader to focus on the paper’s main purpose.

Thesis statement examples

The following examples highlight each type of thesis statement.

Topic: Alternative Energy Sources

Explanatory Thesis: Alternative energy sources that can supplement the use of fossil fuels include solar, wind, and geothermal.

Argumentative Thesis: To combat reliance on foreign sources of fossil fuels, the United States would benefit from focusing on alternative energy options.

Analytical Thesis: Analysis suggests that replacing fossil fuels with alternative energy sources could negatively impact the economy.

Topic: Social Media

Explanatory Thesis: Three of the first platforms that influenced the world of social media include Facebook, Twitter, and Instagram.

Argumentative Thesis: Social media negatively influences society as it increases opportunities for cyberbullying, limits face-to-face interactions, and creates unrealistic expectations.

Analytical Thesis: An analysis of the use of social media suggests itis irrevocably harming the development of teenagers.

Topic: Standardized Testing

Explanatory Thesis: Standardized tests such as the ACT and SAT play a limited role in influencing college acceptance.

Argumentative Thesis: Standardized testing should not be required because it increases anxiety, does not measure progress, and cannot predict future success.

Analytical Thesis: Analysis suggests that standardized testing in elementary and high school negatively impacts students' academic success.

Chapter 6: The Writing Process and Pre-Writing

Elements of a Thesis Statement

When writing an essay, you must focus on a main idea . This idea will stem from a topic you have chosen or been assigned or from a question your instructor has asked. It is not enough merely to discuss a general topic or answer with a yes or no: you will need to form an opinion and then articulate it into a controlling idea – the main idea you will build your thesis on.

A thesis is not the topic itself, but rather your interpretation of the question or subject. When an instructor presents you with a topic, ask, “What do you want to say about it?” Asking and answering this question is vital to forming a thesis that is specific.

A thesis is typically one sentence long and appears near the end of your introduction. It is specific and focuses on one to three points related to a main idea: you will work to prove these points in the body of your paper. Thus, the thesis forecasts the content of the essay and how you will organize your information. A thesis statement does not summarize an issue but rather helps to dissect it.

These OWL resources will help you develop and refine the arguments in your writing.

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.

• North Hennepin Community College & Lake Superior College

So what makes a good working thesis? Ask yourself these questions:

• Is it interesting?
• Is it limited?
• Is it specific?

Interesting thesis

Being interesting doesn’t have to mean the writing is about mutant zombies who become cheerleaders for a professional football team (although that would be interesting!). The question to ask is “To whom is this interesting?” This means making sure your thesis is relevant to your audience. Is it meaningful? Can the audience connect to it or can you make them connect to it? For example, maybe your topic is worm composting. You decide your audience will be a local gardening club because the topic is interesting and relevant to that population. Your thesis, then, would draw more on how to make the topic interesting to that audience.

Maybe you are given an audience and purpose. You have a write a report and present it to your class and your purpose it to teach them something about the class topic (American Literature). You would want to find a topic that interests you and your audience and then create a thesis that will engage the audience as much as possible.

Sample thesis: By using Americana music and Jazz rhythms, the poets of the Harlem Renaissance changed American poetry and made it more relevant and accessible to many people, especially people of color.

Sometimes, your audience is your nursing instructor or a client at work. Then you need to think about what their expectations are. You also need to think about what you know or what you can learn (through research). Find the intersection between those two things, and you will have a good thesis.

Limited thesis

Having a limited thesis means making sure your topic fits your writing assignment. It is too broad or too narrow? Does the thesis fit the assignment or writing project? A thesis for an email to a potential employer needs to be very focused and limited. Emails should be short and to the point:

I want to thank you for the opportunity to interview with St. Joseph’s Hospital, and I am including the additional information we discussed yesterday.

Short, to the point. The email, then, would discuss this additional information. But the “so what” is here to start.

Keep in mind that in the forming of a thesis when writing papers, it's very easy to go too big.

This essay will discuss the Black Lives Matter movement.

Whoa! That’s way too big. What about Black Lives Matters? What kind of essay will this be (informative? persuasive? cause and effect?)? Who is the audience? All of this will help you to limit your thesis and topic.

But you also need to be careful not to go too specific either. What about this thesis statement?

The Black Lives Matters movement began with the killing of Trayvon Martin in Florida.

This is really just a fact. It is not a claim about what might be changed. It is not part of some ongoing debate we are having about how things ought to be. It just states a historical truth. It would be hard to write a whole paper that focuses only on this thesis statement.

Sample thesis: Black Lives Matters was started as a political movement to bring attention to racial bias in the justice system and stems from civil rights movements of the 1950s and 60s.

This would be a thesis claiming to make a certain comment about history and historical facts. It is saying, here is how we should read these historical facts. Notice that one can debate that. Historians certainly do. For example, you can right away see the counterarguments here. Someone could counter:

Black Lives Matters has little to no relationship to the main Civil Rights movements of the 1950s and 1960s; in fact, it is more an offshoot of one of the more radical branches of those movements.

Black Lives Matters was not started as a political movement, but rather, it was a grass-roots community response to a tragedy that morphed into a political movement to bring attention to racial bias in the justice system.

Notice that both of these are plausible counterarguments, and they are also different ways to read a historical fact. So all three would be good thesis statements. The sample thesis above would be a good, supportable, arguable thesis.

Specific thesis

To be specific means giving a why in your thesis. In a working thesis, writers often give the what but not the why. Look at this example:

College students should take online classes.

That’s good that you think college students should take online classes, but why?

Sample thesis: College students should take at least one online class because it will make their schedule more flexible, teach them important technologies, hone their time management skills, and make them better online writers.

Notice that it is also the organization of the paper. You can see the sections right there. There is the first paragraph with the introduction to the topic of online classes. Then there will probably be a section (a paragraph or two) on the flexibility of schedule. Then a section on technology. Then time management. Then a bang-up conclusion. It’s all right there in the thesis statement. This is typical of thesis statements of academic argument research papers.

Sometimes a thesis might be almost the whole piece of writing, like a note to your roommate.

Does this meet the criteria of a good thesis?

• Yes, it’s interesting because Tai, the audience, wants his girlfriend to continue to date him.
• Yes, it’s limited. It says what it needs to say and no more.
• Yes, it’s specific. It gives a what and a why.

What is a thesis statement.

A thesis statement is a sentence that states the main idea of your paper. It is not just a statement of fact, but a statement of position. What argument are you making about your topic? Your thesis should answer that question.

How long should my thesis statement be?

Thesis statements are often just one sentence. Keep thesis statements concise, without extra words or information. If you are having trouble keeping your thesis statement to one sentence, consider the following:

• Is your thesis is specific enough?
• Does your thesis directly supports your paper?
• Does your thesis accurately describes your purpose or argue your claim?
