presents the main arguments that support the 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.

How to Write a Thesis Statement for a Research Paper

4-minute read

• 26th July 2023

A strong thesis statement is the foundation of a successful research paper . The thesis gives focus to your ideas, engages readers, and sets the tone for the rest of the paper. You’ve spent substantial time and effort to craft a well-written and effective study , so you want your thesis statement to accurately reflect the impact of your work.

However, writing a thesis is often easier said than done. So if you’ve already got the arguments, the data, and the conclusions, keep scrolling for our straightforward guide on how to write a thesis statement for a research paper.

What Is a Thesis Statement?

A thesis statement is a clear and succinct assertion that presents the main argument or central idea of a research paper or other academic work. You usually find the thesis, which serves as a road map for the entire piece of writing, at the end of the introductory paragraph. The thesis also highlights the importance and relevance of the research topic , explaining why it’s worth studying and what impact it may have.

A good thesis statement also invites critical discussion and debate. Although your statement should provide a compelling argument , it should also inspire readers to engage with your ideas and potentially challenge or explore alternative viewpoints.

How to Write a Thesis Statement

Your thesis statement should outline the scope and boundaries of the paper and indicate what aspects of the topic you’ll cover. But now that you know what a good thesis statement entails, where should you start? Check out our series of steps below for help on writing an impactful thesis statement that accurately summarizes your research and arguments.

Understand the Purpose of Your Research

Before you can write a thesis statement, you need to understand the purpose and scope of your research. Pinpoint the specific topic or issue you’ll be exploring and the main objective of your paper. You should also familiarize yourself with the existing literature and research related to your topic because these will help you refine your focus and identify gaps in the existing knowledge that your research can address.

Consider the Impact of Your Research

Your thesis statement should answer the question, What is the relevance? – meaning it should tell the reader what the practical implications of your research are, why the research is significant, and what it adds to the broader academic landscape.

Make a Concise Claim or Argument

Your statement should be clear, specific, and concise, conveying the main point of your research in one or two sentences. It should present a claim or argument that you’ll go on to support and defend in your paper, so avoid purely factual or self-evident statements. Be precise in your wording and tailor your thesis statement to the scope of your research – don’t introduce a new or unrelated topic that you don’t expressly address in your paper. The thesis statement is meant to indicate what the reader can expect to find in your paper, and you must support the thesis with evidence throughout.

Revise and Refine the Statement

Crafting a strong thesis statement may require multiple attempts, so take the time to revise and edit it until you’re satisfied that it meets your requirements.

Example Thesis Statement

Below is an example of a strong thesis statement that clearly emphasizes the main points of a research topic:

In this example, the thesis statement clearly identifies the main topic (technology’s impact on education) and presents a strong argument about technology’s positive effects. The thesis conveys the essential message of the research concisely in one sentence, leaving no doubt about the position of the author and what they’ll address in the paper.

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.

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

What’s Covered:

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

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

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

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

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

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

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

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

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

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

Step 2: Figure out what point you want to make

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

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

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

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

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

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

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

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

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

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

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

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

2.5 Writing Thesis Statements

Kathryn Crowther; Lauren Curtright; Nancy Gilbert; Barbara Hall; Tracienne Ravita; and Kirk Swenson

To be effective, all support in an essay must work together to convey a central point; otherwise, an essay can fall into the trap of being out of order and confusing. Just as a topic sentence focuses and unifies a single paragraph, the thesis statement focuses and unifies an entire essay. This statement is like a signpost that signals the essay’s destination; it tells the reader the point you want to make in your essay, while the essay itself supports that point.

Because writing is not a linear process, you may find that the best thesis statement develops near the end of your first draft. However, creating a draft or working thesis early in the writing project helps give the drafting process clear direction. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

A thesis is not just a topic, but rather the writer’s comment or interpretation of the question or subject. For whatever topic you select (for example, school uniforms, social networking), 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.

In the majority of essays, a thesis is one sentence long and appears toward the end of the introductory paragraph. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body paragraphs. 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.

Working Thesis Statements

A strong thesis statement must have the following qualities:

• It must be arguable.  A thesis statement must state a point of view or judgment about a topic. An established fact is not considered arguable.
• It must be supportable.  The thesis statement must contain a point of view that can be supported with evidence (reasons, facts, examples).
• It must be specific. A thesis statement must be precise enough to allow for a coherent argument and remain focused on the topic.

Examples of Appropriate Thesis Statements

• Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
• 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.
• The societal and personal struggles of Troy Maxson in the play Fences symbolize the challenges of black males who lived through segregation and integration in the United States.

Pitfalls to Avoid

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 Example

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.

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.

Advertising companies use sex to sell their products.

A thesis is weak when the statement is too broad.

The life of Abraham Lincoln was long and challenging.

Ways to Revise Your Thesis

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 develop new ideas and reasons for those ideas. 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:

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

Pinpoint and Replace Example

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.

Explanation:  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 their research and gain more direction in their writing. The revised thesis makes a more specific statement about success and what it means to work hard.

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

Clarify Example

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.

Explanation:  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 and more accurately defines their stance, which will better guide the writing of the essay.

• 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.

Replace with Action Verbs Example

Working thesis:  Kansas City school teachers 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.

Explanation:  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.

• Who is not paying the teachers enough?
• How much is considered “enough”?
• What is the problem?
• What are the results?
• Omit any general claims that are hard to support.

Omit General Claims Example

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

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

Explanation:  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?

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

• Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
• Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
• Is the thesis complex enough to require a whole essay's worth of argument?  
• Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
• Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

Supporting an argumentative thesis, 1. thesis development.

Remember that a thesis is a single sentence that expresses the controlling idea of a written work. In other words, the thesis is the core of the essay. It guides the goals and structure of the work by letting the reader know what the writer will be discussing in the body paragraphs, and in what order.

Also remember that there is a significant difference between a thesis and a topic. A topic is the broad subject of a written work and can include multiple thesis statements. The thesis is a focused point or argument about something within the topic.

IN CONTEXT Suppose you were assigned the topic of pet ownership. You wouldn't be able to write an essay based on that topic—it's too broad. First, you must decide which aspect of pet ownership you want to write about or communicate to readers. You might, for example, make the following statement: Although many people assume that owning a pet is easy, it actually comes with a great deal of responsibility, such as grooming, feeding, and training. Here's another option: Due to their companionship, understanding nature, and ability to help during emergencies, pets can fit the definition of lifesavers. As you can see, these two thesis statements are very different and are only related through their very broad shared topic of pet ownership.

Once you've selected a topic and a thesis, you must support the thesis by developing your ideas effectively. This is accomplished through a process of clearly articulating your ideas and supporting them with evidence and reasoning throughout the essay.

So, when writers refer to development, they're not only referring to development of the essay as a whole, but also to the process that takes place at the paragraph level. Paragraphs function like mini essays: Each of them contains their own main ideas, topic sentences, and support.

2. Main Ideas and Claims

To effectively state and support a thesis, most essays must also promote related points—points that, together, prove or support the thesis. Recall that, in writing, these are called main ideas. A main idea is a point or concept that drives one or more body paragraphs of an essay. Each main idea in an essay should contribute to, or support, the thesis statement in some way.

A claim is a type of main idea in which the writer makes a statement that must be defended. A claim is an assertion made by the writer. The thesis statement is thus the primary claim of the essay—the object of all of the essay's support, ideas, and evidence.

A main idea, when coupled with a claim, is usually the controlling idea of the paragraph. When working on the level of the paragraph, the main idea and the controlling idea are synonymous.

hint A controlling idea is the core idea that drives the writing's goals and structure. Note that consecutive paragraphs will sometimes focus on one controlling idea. This can be a sign of a complex and fully realized main idea. Don't worry if you find this happening in your writing.

terms to know Main Idea In writing, a point or concept that drives one or more body paragraphs of an essay. Claim A type of main idea in which the writer makes a statement that must be defended.

3. Evidence and Support

The thesis statement is the main point of the essay, so it needs support in order to hold up. Support refers to any evidence, logic, or other technique (e.g., clarification, expansion of ideas) that bolsters an essay's claims. The purpose of support isn't only to prove that a thesis is true, but also to explain or strengthen the essay's main ideas.

• Facts and data
• Personal research
• Citation of the research of others
• Personal experience

Because essays consist of paragraphs that use forms of support to back up the thesis, it's important to consider paragraphs in order to understand the essay as a whole. As mentioned above, paragraphs are like miniature essays that include a topic sentence (i.e., the sentence that states the paragraph's thesis) and support—usually evidence for the topic sentence.

terms to know Support Any evidence, logic, or other technique that bolsters an essay's claims. Evidence Proof of the validity of a claim or claims.

4. Thesis Support in Action

Following are paragraphs from the same essay which demonstrate how an overall thesis might be introduced, developed, and supported. This first paragraph serves as the essay's introduction:

When you think about your goofy pet dog, your lazy house cat, or even your loud pet parrot, you might not consider that they could save your life. Mounting evidence suggests that pets are more than a playful mess to clean up after; they are key to a happy, healthy life. Due to their companionship, understanding nature, and ability to help during emergencies, pets can fit the definition of lifesavers.

The thesis appears as the last sentence of the paragraph: “Due to their companionship, understanding nature, and ability to help during emergencies, pets can fit the definition of lifesavers.”

Because of this thesis, we know that the main point and narrowed-down topic of the essay is that pets are lifesavers, and we know that the main ideas related to that point are companionship, an understanding nature, and ability to help during emergencies. That helps us to figure out what kind of evidence and support may be included in this essay: Perhaps the essay will use data about the health benefits of owning a pet, perhaps it will discuss research from others who have investigated this topic, or perhaps it will include descriptions of personal experience.

Now consider this next paragraph, keeping the essay's thesis in mind as you do:

The companionship of pets offers health benefits, demonstrating the lifesaving qualities of pets. There are all kinds of pets that individuals or families can adopt. Some of the most traditional pets are dogs, cats, birds, rodents (such as hamsters and guinea pigs), and fish. Less common pets include rabbits, small pigs, raccoons, and snakes and other reptiles. Exotic animals might also make excellent pets but may require a special permit and special care. There is an ideal type of pet for each individual or family.

The topic sentence of this is paragraph is “The companionship of pets offers health benefits, demonstrating the lifesaving qualities of pets,” which means that the support in this paragraph should focus on the main idea of companionship mentioned in the thesis. So, is the support here effective for the main idea of the paragraph and the essay's thesis?

No, it is not. All of the sentences that come after the topic sentence are discussing different types of pets that individuals and families can adopt. The author gives examples of different types of pets and simply states that there is an ideal pet for each individual or family. Even though this information is related to the broader topic of pet ownership, it does not belong in this essay. It does not support the idea that the companionship of pets offers health benefits (the main idea of this paragraph), and it does not support the overall claim of the thesis (that pets fit the definition of lifesavers) because it does not address pets' companionship, understanding nature, or ability to help during emergencies.

In order to better support the topic sentence “The companionship of pets offers health benefits, demonstrating the lifesaving qualities of pets,” and to therefore better support the thesis, here is a revised version of this paragraph:

The companionship of pets offers health benefits, demonstrating the lifesaving qualities of pets. Both mental and physical health can improve when owning a pet. Petting or caring for a dog or cat lowers levels of stress and combats loneliness. Dog owners in particular may find themselves socializing more often when taking their dog for walks and to dog parks. In addition, walking a dog can lower blood pressure and decrease the risk of heart disease (Fields, 2013). By improving the health of their owners through companionship, pets improve—and even save—these owners' lives.

In this version of the paragraph, the support provided directly relates to both the topic sentence and thesis. There are facts, such as that petting or caring for a dog or cat lowers levels of stress and combats loneliness, dog owners socialize more, and walking a dog can lower blood pressure and decrease the risk of heart disease. These facts help to support the idea that the companionship offered by pets comes with health benefits.

Additionally, the support in this paragraph supports the thesis, which lists companionship as one of its main ideas.

summary In this lesson, you learned that thesis development is the process in which thesis statements are represented throughout an essay by main ideas and claims , which are in turn backed up by different kinds of support , such as evidence . You then looked at examples of thesis support in action by reading an introductory and body paragraph from a sample essay. Best of luck in your learning!

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.

Argument Structure and Thesis Statements

• Getting Started
• Planning an Argument
• Structure of an Argument

Thesis Statement

• Toulmin Model of Argument

A thesis statement represents the most important thing you want to say about your topic. It is the major argumentative claim about your topic. As such, it will need to be supported by evidence and other supporting claims. 

A thesis statement must be a specific claim about your topic. It cannot be a general fact although it must be supported by fact. It cannot be a claim that anyone would readily believe – you must argue for it.

Not all research articles that you may read use an argumentative thesis statement. The reason for this is that some articles are meant to describe or explain facts. However, writers who are arguing in support of a particular position or claim about a topic, must compose a thesis statement. 

The thesis statement is usually the last, or next to last, sentence in your introduction. Your introduction serves to announce and explain the importance of your topic and any issues associated with it. Your thesis, however, structures your argument and hints at what kind of evidence and support you may present. 

There is no specific sentence structure or formula for a thesis statement except that it will usually contain key words related to your topic and to your main argument. There are common problems with thesis statement attempts that can be instructive. The following examples will show you some common problems with thesis statement attempts. Consider each of the following:

Thesis? Windsurfing is a sport that everyone can enjoy. No. This statement cannot be supported. Better: Windsurfing is an exciting sport that takes physical stamina and dedication of time to practise in order to master and enjoy.  Consider what kinds of supports would be needed to support the new thesis.

Thesis? This paper will discuss nursing as a career. No. This statement is an announcement; it is also a fact of what the writer will discuss in the paper. Better: Although often misunderstood as an unrewarding profession, a career in nursing offers professional leadership roles and numerous opportunities to make meaningful change in people’s lives and society as a whole. [Note: the idea of an “unrewarding profession” here is an “opposing viewpoint.” Push against opposing viewpoints to emphasize your position]

Thesis? Holistic nursing care is more than a focus on disease, and it is also a flexible career with global opportunities. No – this statement contains more than one idea. Better:  Nursing care is more than a focus on disease. The holistic approach of nursing care focuses on the patient’s response to disease or illness and also responds to meeting the emotional, social, and spiritual needs of patients and their families. [Note: This thesis statement has several ideas, but the ideas here are supporting claims to the holistic approach.]

Thesis? Recreational running has many benefits. No. This statement is too broad.  It announces the topic but lacks focus. Better: Recent research indicates that regular recreational running has demonstrable physiological and psychological benefits.

[Note: This thesis statement is a type that may have been suggested to your by your teachers in the past. It is a useful way to organize ideas for some types of writing tasks such as providing information (e.g., patient educational materials).]

Thesis Statements: Crafting a Claim Backed by Reasoning

Overview of thesis statements.

A clear and well-developed thesis statement is, in many cases, the backbone of most essays and research papers. The thesis statement presents your argument to your reader, making your stance or your position clear. A solid thesis statement can also provide structure for your writing. Even in non-argumentative writing, such as narrative essays, you can still use your thesis statement to express your purpose for writing.

In your thesis statement, you can provide the overarching claims you plan to make, as well as your reasoning for those claims. You can think of the thesis statement as being made up of two parts: the position and the reasoning. The position is the overall point you are making, and the reasoning is the explanation or logic behind that position. When you include both the position and the reasoning, your thesis statement shows your readers how you intend to structure your writing. For more on organization in your writing, see the Stone Writing Center (SWC) handout on this topic.

Argumentative Thesis Statements

When it comes to argumentative thesis statements, these statements are not argumentative for the sake of conflict; rather, you are writing to inform and persuade your readers, advancing their understanding of your topic. It might be helpful to even think of argumentative thesis statements like a road map that guides your writing as a whole. For more on argumentative writing, see the SWC handouts on this topic.

An argumentative thesis statement makes a clear assertion, taking a stance and providing details to support that stance. An effective argumentative thesis statement helps to persuade the reader by providing an outline of the main claims and reasoning for those claims.

Examples of Thesis Statements

Each of these sample thesis statements takes a stance on a subject and states a claim, then provides supporting details to convey the reasoning for the claim/s. The position or claim is in bold , and the reasoning is in italics .

Adults should eat apples more regularly because the fruit has many health benefits including lowering risk for heart disease, improving digestion, and promoting weight loss.

The Stone Writing Center is a convenient learning resource for Del Mar College as it provides a place where students can get help with their writing and offers multiple services for all writers.

Because of the convenience, low prices, and diverse options , people should get rid of cable and join streaming services instead.

Del Mar College is a great option to further one’s education because it offers many different academic programs, has a lower cost than surrounding universities, and provides dual-enrollment courses for high school students.

Because public libraries give citizens access to free books, technological resources, and other helpful learning programs, these institutions deserve more city funding.

To demonstrate the theme that family can be made through friends, The Avengers* movie uses characterization, conflict, and allusion. *Note: Movie titles, such as The Avengers , are usually italicized.

By providing readers with the main claim or position, as well as the reasoning or explanations for said claim, thesis statements allow you to effectively communicate the overall argument you intend to make in your writing.

Module 7: Drafting a Research Paper

What makes a thesis statement work, learning objectives.

Recognize the qualities of a strong thesis statement

A good thesis statement packs a lot of punch into a relatively short sentence. If you’ve done your job, the reader should be able to get your topic, claim, argument, and main points, all from one clear statement. There are a few key components to watch out for when evaluating whether or not you’ve written a strong thesis.

A Strong Thesis Statement ADDS UP:

You should be confident in your argument. Don’t use phrases like “I feel” or “I believe” – these will weaken your argument and convey to the reader that you are the only person who feels the way you do. You should take an authoritative stance to persuade your readers to accept your argument and open their minds to what you have to say. There’s no room to be wishy-washy when it comes to a thesis, especially not in an argumentative paper. You need to come in with a firm stance and assert your conviction. After all, if you don’t stand behind your argument, why should the reader?

• This statement leaves a lot of wiggle room and doesn’t really sound like even you are totally sold on this concept. A pros and cons approach ends up feeling more informative than it is persuasive.
• Every good persuasive paper should acknowledge the opposition, but the trick is to demonstrate to the reader that your claim is still the best option. The above statement establish a firm but realistic stance.

Descriptive

Many writers are afraid of “giving it all away” in their introduction and thesis. After all, why would the reader keep going if they know what’s going to happen? Perhaps this is a result of watching too many M. Night Shyamalan movies. When it comes to academic writing, it’s important to lay it all out for your audience so they have clear expectations of what you’re going to cover in your essay.  This is not to say that you need to go in-depth with your intended points, but you do want to show your readers what your paper is about and why it’s important.

• While this thesis makes a strong assertion, can likely be proven through research, and has a strong focus, it’s unclear how reading can actually benefit students. Including a brief mention of the paper’s main points gives the reader a much better idea of what to expect and shows foresight and planning on the part of the writer.
• In this revised thesis we have the same core argument — reading is good for kids — with the addition of how it’s good for them. This gives the reader an idea of how you’re going to prove this argument and the general structure of the rest of the paper.

To determine whether your thesis statement is debatable, ask yourself: could someone disagree with this statement from a position other than “because I say so”? If not, then your thesis probably isn’t debatable.

• Although a reader could disagree with this statement from their own point of view, the argument wouldn’t get any further than “no they’re not… yes they are…”.
• Someone could look at the same set of evidence (the analysis of camera movements) and find a different cause or explanation.

Substantiated

For any claim you make in your thesis, you must be able to provide reasons and examples for your opinion. In some cases (such as a personal essay), you can rely on personal observations to support your claims, but for most research papers you’ll be consulting outside sources. In most academic fields, you should primarily rely on peer-reviewed sources.

• You may believe a claim like this strongly, but there’s no way to prove it within the logical context of a research paper.
• This claim can be substantiated by passages from the books.

A strong thesis statement needs to express one main idea. Even if there are several sub-points, the main idea should be singular and unified.

• This thesis takes us in two directions: an argument about MLM and pyramid schemes, and an argument about the potential benefits of MLM.
• This thesis connects both pieces into one main idea. The difference between MLM and pyramid schemes becomes a sub-point of the claim that many companies fail to see the potential benefits of MLM strategies.

A thesis statement must be precise enough to allow for a coherent argument and to remain focused on the topic. Don’t make a potentially complex idea even more confusing by trying to cover too many topics. It can be easy to get off track in an effort to be as thorough as possible, and if your thesis is unfocused, the rest of your paper will be, too. Similarly, if your thesis is too broad, it’s going to be difficult to develop a solid argument throughout your essay.

• This thesis covers too much ground and leaves the reader with more questions than answers. What kind of animals? What constitutes “ethical”? According to whom? This statement is too unfocused to give the reader an idea of what the paper is actually about.
• This statement provides enough detail to make the terms and boundaries of the argument clear.

Making Arguments and Writing Theses

What is an argument?

An argument takes a stand on an issue that is  debatable . It seeks to  persuade  an audience of a point of view in much the same way that a lawyer argues a case in a court of law. It is  NOT  a description or a summary.

• This is an argument: “Although it may seem that internal discord and external barbarian invasions were separate problems for the Roman Empire in the fourth century, these developments were fundamentally interrelated and formed the single most important explanation for the long-term decline of Rome.”
• This is not an argument: “In this paper, I will elucidate the reasons for the collapse of the Roman Empire in the two tumultuous centuries leading up to the sack of its capital city in 410 by the notorious Visigoth king Alaric.”

What is a thesis?

A thesis statement states the  main argument  of your project and describes, briefly,  how you will prove your argument .  In other words, it also states how you will organize your body of evidence in support of the argument.

• This is an vague argument, and not yet a thesis: “The Roman Empire fell due to multiple interrelated reasons.”
• This is a thesis: “The barbarian invasions from the late third to the early fifth century were a direct result of policy changes by the Roman government responding to political struggles within the empire, culminating in the collapse of the Roman Empire at the hands of the Germanic tribes from the north.”

A thesis makes a specific statement to the reader about what you will be trying to argue. Your thesis can be more than one sentence, but should not be longer than a paragraph.  Do not state evidence or use examples in your thesis paragraph.  

A Thesis Helps You and Your Reader

Your  blueprint for writing:

• Helps you focus and clarify your ideas.
• Provides a “hook” on which you can “hang” your topic sentences.
• Can (and should) be revised as you further refine your evidence and arguments. New evidence often requires you to change your thesis.
• Gives your paper a unified structure and point.

Your  reader’s  blueprint for reading:

• Serves as a “map” to follow through your paper.
• Keeps the reader focused on your argument.
• Signals to the reader your main points.
• Engages the reader in your argument.

Tips for Writing a Good Thesis

• Find a Focus :  Choose a thesis that explores an aspect of your topic that is important to you, or that allows you to say something insightful about your topic. For example, if your project seeks to analyze women’s domestic labor during the late fifteenth century, you might decide to focus on the products they produced at home.
• Look for Patterns : After determining a general focus, go back and look more closely at your evidence. As you re-examine your evidence and identify patterns, you will develop your argument and some conclusions. For example, you might find that as men’s access to professional training increased, women made fewer textiles at home, though they generally retained their production of butter and ale.

Strategies for Developing a Thesis Statement

Here are four ways to begin to develop your thesis. These will not necessarily result in a finished product, but will give you a place to start.

Strategy 1:  Spend time ruminating over your topic. Make a list of the ideas you want to include in the essay, and then think about how to group them under several different headings. Often, you will see an organizational plan emerge from the sorting process.

Strategy 2:  Write a sentence that summarizes the main idea of the essay you plan to write.

Main Idea :  Women’s domestic labor during the later Middle Ages contributed to the growth of the early industrial economy in Europe.

Strategy 3:  Use a formula to develop a working thesis statement (which you will need to revise later). Here are a few examples:

• Although most readers of _________ have argued that _________, closer examination shows that _________.
• ________ used _________ and _________ to prove that _________.
• Historical event “X” is a result of the combination of _________, _________, and _________.

Strategy 4:  Since your project instructions asks you to develop a specific historical question, turn the question into an assertion and give reasons for your statement.

Research Question : How did women’s domestic labor change between 1348 and 1500? How were changes in their work important to late medieval economic culture in Germany?

Beginning thesis : Between 1348 and 1500 women’s domestic labor changed as women stopped producing home-made textiles, although they continued to produce butter and ale. With the cash women earned from the sale of butter and ale they purchased cloth imported from Flanders and Italy, which in turn, helped increase early industrial production in those areas.

These strategies all should help you develop two characteristics all thesis statements should have: they state an argument and they reveal how you will make that argument. Your thesis probably still needs revising but these strategies may provide a good start.

Refine, Refine, Refine

As you work on your project, your ideas will change and so will your thesis. Here are examples of weak and strong thesis statements.

• Unspecific thesis : “Francis of Assisi was an important figure in the development of Christian attitudes about nature.”

  This thesis lacks an argument. Why was Francis an important leader?

• Specific thesis : “Francis of Assisi offered a new interpretation of Christian asceticism that responded to the frustrations felt my many urban dwellers with the commercial economy of the thirteenth century, while using simple religious language that attracted people who were uncomfortable with impenetrable scholastic theology of the period.”

This thesis has an argument: Francis’s interpretation of Christianity became popular  because  it satisfied two different frustrations felt by many people in thirteenth-century Europe.

• Unspecific thesis : “At the end of the fifteenth century French women faced difficulty when they attempted to enter universities.”

No historian could argue with this general statement and uninteresting thesis.

• Specific thesis : “At the end of the fifteenth century French women experienced misogynist attacks from scholastics when they petitioned to enter universities  primarily   because  theologians were concerned with protecting the monopoly that males had on priesthood, which was required for entry into academia.”

This thesis statement asserts that theologians attacked women who wanted a formal education  because  they feared that  if  women were allowed into universities they would be granted clerical status, which might threaten the male monopoly on priesthood.

Making an Argument

Your thesis is defenseless without you to prove that its argument holds up under scrutiny. Your reader expects you to provide all of the evidence to prove your thesis. There are two categories of evidence that you can use:

• Primary sources: treatises, letters, diaries, newspaper accounts, government documents, an organization’s meeting minutes and pamphlets.
• Secondary sources: articles and books that explain and interpret historical events.

How can you use this evidence?

• Make sure the examples you select from your available evidence address your thesis.
• Use evidence that your reader will deem credible. This means sorting through your sources, and identifying the clearest and fairest. It also means paying careful attention to the credibility of the source. This is especially important when dealing with web-based sources. Be sure to understand the biases and shortcomings of each piece of evidence. When in doubt consult with your professor or teaching assistant.
• Avoid broad generalizations that your reader may question by appealing to specific evidence.
• Use evidence to address an opposing point of view. How do your sources give examples that refute another historian’s interpretation?

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.

Five Ways of Looking at a Thesis

1. a thesis creates an argument that builds from one point to the next, giving the paper a direction that the audience can follow as the paper develops..

This point often separates the best theses from the pack. A good thesis can prevent the two weakest ways of organizing a critical paper: the pile of information and the plot summary with comments. A paper that presents a pile of information will frequently introduce new paragraphs with transitions that simply indicate the addition of more stuff. (“Another character who exhibits these traits is X,” for instance.) Consider these examples:

A: The Rules and Jane Austen’s Northanger Abbey both tell women how to act.

B: By looking at The Rules , a modern conduct book for women, we can see how Jane Austen’s Northanger Abbey is itself like a conduct book, questioning the rules for social success in her society and offering a new model.

Example A would almost inevitably lead to a paper organized as a pile of information. A plot summary with comments follows the chronological development of a text while picking out the same element of every segment; a transition in such a paper might read, “In the next scene, the color blue also figures prominently.” Both of these approaches constitute too much of a good thing. Papers must compile evidence, of course, and following the chronology of a text can sometimes help a reader keep track of a paper’s argument.

The best papers, however, will develop according to a more complex logic articulated in a strong thesis. Example B above would lead a paper to organize its evidence according to the paper’s own logic.

2. A thesis fits comfortably into the Magic Thesis Sentence (MTS).

The MTS: By looking at _____, we can see _____, which most readers don’t see; it is important to look at this aspect of the text because _____.

Try it out with the examples from the first point:

A: By telling the story of Wesley and Buttercup’s triumph over evil, The Princess Bride affirms the power of true love.

B: Although the main plot of The Princess Bride rests on the natural power of true love, an examination of the way that fighting sticks–baseball bats, tree branches, and swords–link the frame story to the romance plot suggests that the narrator’s grandson is being trained in true love, that love is not natural but socialized.

Notice that the MTS adds a new dimension to point number one above. The first part of the MTS asks you to find something strange (“which most readers don’t see”), and the second part asks you to think about the importance of the strangeness. Thesis A would not work at all in the MTS; one could not reasonably state that “most readers [or viewers] don’t see” that film’s affirmation of true love, and the statement does not even attempt to explain the importance of its claim. Thesis B, on the other hand, gives us a way to complete the MTS, as in “By looking at the way fighting sticks link the plot and frame of The Princess Bride , we can see the way the narrator’s grandson is trained in true love, which most people don’t see; it is important to look at this aspect of the text because unlike the rest of the film, the fighting sticks suggest that love is not natural but socialized.” One does not need to write out the MTS in such a neat one-sentence form, of course, but thinking through the structure of the MTS can help refine thesis ideas.

3. A thesis says something about the text(s) exclusively .

If a thesis could describe many works equally well, it needs to be more specific. Let’s return to our examples from above:

Try substituting other works:

A: By telling the story of Darcy and Elizabeth’s triumph over evil, Pride and Prejudice affirms the power of true love.

Sure, that makes sense. Bad sign.

B: Although the main plot of Pride and Prejudice rests on the natural power of true love, an examination of the way that fighting sticks–baseball bats, tree branches, and swords–link the frame story to the romance plot suggests that the grandson is being trained in true love, that it is not natural but socialized.

Um, nope. Even if you have never read Pride and Prejudice , you can probably guess that such a precise thesis could hardly apply to other works. Good sign. The point here is that the thesis needs to be specific enough that its meaning relates to the specific work(s) you are writing about -- be it fiction or nonfiction.

4. A thesis makes a lot of information irrelevant.

If the thesis is specific enough, it will make a point that focuses on only a small part of the text be analyzed or a particular aspect of a larger topic. A writer should ultimately apply that point to the work as a whole, but a thesis will call attention to specific parts of it. Let’s look at those examples again. (This is the last time, I promise.)

One way of spotting the problem with Example A is to note that a simple plot summary would support its point. That is not of true example B, which tells the reader exactly what moments the paper will be discussed and why. The thesis is focused and concentrated.

5. Remember to Address the Work as a Whole: The “So What?”

As you complete your analysis, remember to think about what the effect this will have on the world of academia.

• Does your thesis introduce your topic in a clear way?
• Does the introduction mention what you will be addressing? Social constructs, gender issues, etc.

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 ten-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.

For a longer piece of writing, the main idea should be broader than the main idea for a shorter piece of writing. Be sure to frame a main idea that is appropriate for the length of the assignment. Ask yourself, “How many pages will it take for me to explain and explore this main idea in detail?” Be reasonable with your estimate. Then expand or trim it to fit the required length.

Developing Thesis Statements from Topics

The big idea, or controlling idea, you want to present in an essay is expressed in a thesis statement. 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.

Table 5.1 “Topics and Thesis Statements” compares topics and thesis statements.

Table 5.1 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.

Using the topic you selected in Section 4.6 “ Prewriting Strategies ”, develop a working thesis statement that states your controlling idea for the piece of writing you are doing. On a sheet of paper, write your working thesis statement.

You will make several attempts before you devise a working thesis statement that you think is effective. Each draft of the thesis statement will bring you closer to the wording that expresses your meaning exactly. Sometimes, this refinement of the thesis statement happens after your write your first draft of the paper.

Guidelines for Drafting a Thesis Statement

It helps to understand why readers value the arguable thesis. What larger purpose does it serve? Readers will bring a set of expectations to an essay. If writers can anticipate the expectations of their readers, the better they will be able to persuade the audience to find the arguments convincing, interesting, and relevant.

Academic readers (and readers more generally) read to learn something new. They want to see the writer challenge commonplaces—either everyday assumptions about the object of study or truisms in the scholarly literature. In other words, academic readers want to be surprised so that their thinking shifts or at least becomes more complex by the time they finish reading an essay. Good essays problematize what we think we know and offer an alternative explanation in its place. They leave their reader with a fresh perspective on a problem.

We all bring important past experiences and beliefs to our interpretations of texts, objects, and problems. Writers can harness these observational powers to engage critically with what they are studying. The key is to be alert to what strikes you as strange, problematic, paradoxical, or puzzling about your topic. If writers can articulate this and a claim in response, they are well on their way to formulating an arguable thesis in the introduction.

How do I set up a “problem” and an arguable thesis in response?

All good writing has a purpose or motive for existing. The thesis is the writer’s surprising response to this problem or motive. This is why it seldom makes sense to start a writing project by articulating the thesis. The first step is to articulate the question or problem your paper addresses.

Here are some possible ways to introduce a conceptual problem in your paper’s introduction.

1. Challenge a commonplace interpretation (or your own first impressions).

How are readers likely to interpret this source or issue? What might intelligent readers think at first glance? (Or, if you’ve been given secondary sources or have been asked to conduct research to locate secondary sources, what do other writers or scholars assume is true or important about your primary source or issue?)

What does this commonplace interpretation leave out, overlook, or under-emphasize?

2. Help the reader see the complexity of your topic.

Identify and describe for the reader a paradox, puzzle, or contradiction in a primary source(s).

What larger questions does this paradox or contradiction raise for readers?

3. If research is part of the assignment, piggyback off another scholar’s research.

4. If research is part of the assignment, identify a gap in another scholar’s or a group of scholars’ research.

Summarize another scholar’s argument about your topic, primary source, or case study and explain to the reader why this claim is interesting. Or, summarize how scholars in the field tend to approach the topic.

Next, explain what important aspect this scholarly representation misses or distorts. Introduce the particular approach to the topic and its value.

5. If research is part of the assignment, bring in a new lens for investigating the case study or problem.

Summarize how a scholar or group of scholars has approached the topic.

Introduce a theoretical source (possibly from another discipline) and explain how it helps to address this issue from a new and productive angle.

Tip : your introductory paragraph will probably look like this:

Testing Your Thesis

Test a thesis statement’s arguability by asking the following questions:

1) Does the thesis only or mostly summarize a source?

If so, try some of the exercises above to articulate the paper’s conceptual problem or question.

2) Is the thesis arguable – can it be supported by evidence, and is it surprising and contentious?

If not, return to the sources and practice the exercises above.

3) Is the thesis about the primary source, or is it about the world?

If it’s about the world, revise it so that it focuses on primary source(s). Remember to include solid evidence to support the thesis.

"THREE-STORY THESIS STATEMENTS" BY AMY GUPTIL

How do you produce a good, strong thesis? And how do you know when you’ve gotten there? Many instructors and writers find useful a metaphor based on this passage by Oliver Wendell Holmes Sr.: 3

There are one-story intellects, two-story intellects, and three-story intellects with skylights. All fact collectors who have no aim beyond their facts are one-story men. Two-story men compare, reason, generalize using the labor of fact collectors as their own. Three-story men idealize, imagine, predict—their best illumination comes from above the skylight.

One-story theses state inarguable facts. Two-story theses bring in an arguable (interpretive or analytical) point. Three-story theses nest that point within its larger, compelling implications. 4

The biggest benefit of the three-story metaphor is that it describes a process for building a thesis. To build the first story, you first have to get familiar with the complex, relevant facts surrounding the problem or question. You have to be able to describe the situation thoroughly and accurately. Then, with that first story built, you can layer on the second story by formulating the insightful, arguable point that animates the analysis. That’s often the most effortful part: brainstorming, elaborating and comparing alternative ideas, finalizing your point. With that specified, you can frame up the third story by articulating why the point you make matters beyond its particular topic or case.

Thesis: that’s the word that pops at me whenever I write an essay. Seeing this word in the prompt scared me and made me think to myself, “Oh great, what are they really looking for?” or “How am I going to make a thesis for a college paper?” When rehearing that I would be focusing on theses again in a class, I said to myself, “Here we go again!” But after learning about the three story thesis, I never had a problem with writing another thesis. In fact, I look forward to being asked on a paper to create a thesis.

Timothée Pizarro

For example, imagine you have been assigned a paper about the impact of online learning in higher education. You would first construct an account of the origins and multiple forms of online learning and assess research findings about its use and effectiveness. If you’ve done that well, you’ll probably come up with a well considered opinion that wouldn’t be obvious to readers who haven’t looked at the issue in depth. Maybe you’ll want to argue that online learning is a threat to the academic community. Or perhaps you’ll want to make the case that online learning opens up pathways to college degrees that traditional campus-based learning does not. In the course of developing your central, argumentative point, you’ll come to recognize its larger context; in this example, you may claim that online learning can serve to better integrate higher education with the rest of society, as online learners bring their educational and career experiences together. To outline this example:

• First story : Online learning is becoming more prevalent and takes many different forms.
• Second story : While most observers see it as a transformation of higher education, online learning is better thought of an extension of higher education in that it reaches learners who aren’t disposed to participate in traditional campus-based education.
• Third story : Online learning appears to be a promising way to better integrate higher education with other institutions in society, as online learners integrate their educational experiences with the other realms of their life, promoting the freer flow of ideas between the academy and the rest of society.

Here’s another example of a three-story thesis: 5

• First story : Edith Wharton did not consider herself a modernist writer, and she didn’t write like her modernist contemporaries.
• Second story : However, in her work we can see her grappling with both the questions and literary forms that fascinated modernist writers of her era. While not an avowed modernist, she did engage with modernist themes and questions.
• Third story : Thus, it is more revealing to think of modernism as a conversation rather than a category or practice.

Here’s one more example:

• First story : Scientists disagree about the likely impact in the U.S. of the light brown apple moth (LBAM) , an agricultural pest native to Australia.
• Second story : Research findings to date suggest that the decision to spray pheromones over the skies of several southern Californian counties to combat the LBAM was poorly thought out.
• Third story : Together, the scientific ambiguities and the controversial response strengthen the claim that industrial-style approaches to pest management are inherently unsustainable.

A thesis statement that stops at the first story isn’t usually considered a thesis. A two-story thesis is usually considered competent, though some two-story theses are more intriguing and ambitious than others. A thoughtfully crafted and well informed three-story thesis puts the author on a smooth path toward an excellent paper.

The concept of a three-story thesis framework was the most helpful piece of information I gained from the writing component of DCC 100. The first time I utilized it in a college paper, my professor included “good thesis” and “excellent introduction” in her notes and graded it significantly higher than my previous papers. You can expect similar results if you dig deeper to form three-story theses. More importantly, doing so will make the actual writing of your paper more straightforward as well. Arguing something specific makes the structure of your paper much easier to design.

Effective Thesis Statements

As mentioned before, a thesis statement is the controlling idea of your essay. It is the main idea that all of the other sentences in the essay relate to. After gathering information about your topic, you need to figure out what you want to say about it.

An effective thesis statement has two major characteristics.

1. An effective thesis statement makes a point about a topic. For this reason, it must do more than state a fact or announce what you plan to write about.

Statement of fact: The military recruits students in high schools.

Announcement: In this essay, I would like to discuss what’s wrong with military recruitment in high schools.

List thesis: We should not allow the military to recruit in high schools because recruiters violate privacy, manipulate naïve young people, and target low-income youth.

Effective thesis: We should end the abusive and discriminatory practice of military recruitment in high schools.

A statement of fact is not an effective thesis statement because it does not take a position, giving you nothing to develop in your essay. Likewise, an announcement of what you plan to write about in your essay does not take a position on the issue, leaving you with nothing to develop. A good thesis statement makes a claim that is arguable.

2. The most effective thesis statements do not list your main points but unite your main points into a larger, central idea. The list thesis above looks strong, but notice how the effective thesis connects the three points with the words “abusive” and “discriminatory.” Now we know how the three points relate to each other; they are more than just a list.

To turn three or four “reasons” or topic sentences into a thesis, consider what they have in common and what your overall point is.

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:

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

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

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

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 manager 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 manager 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 4 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 their research and gain more direction in their 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 4.6 " Prewriting Strategies " 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: Kansas City 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

In an earlier section you determined your purpose for writing and your audience. You then completed a free writing 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.

Writing a Thesis and Making an Argument

Almost every assignment you complete for a history course will ask you to make an argument. Your instructors will often call this your "thesis"– your position on a subject.

What is an Argument?

An argument takes a stand on an issue. It seeks to persuade an audience of a point of view in much the same way that a lawyer argues a case in a court of law. It is NOT a description or a summary.

• This is an argument: "This paper argues that the movie JFK is inaccurate in its portrayal of President Kennedy."
• This is not an argument: "In this paper, I will describe the portrayal of President Kennedy that is shown in the movie JFK."

What is a Thesis?

A thesis statement is a sentence in which you state an argument about a topic and then describe, briefly, how you will prove your argument.

• This is an argument, but not yet a thesis: "The movie ‘JFK’ inaccurately portrays President Kennedy."
• This is a thesis: "The movie ‘JFK’ inaccurately portrays President Kennedy because of the way it ignores Kennedy’s youth, his relationship with his father, and the findings of the Warren Commission."

A thesis makes a specific statement to the reader about what you will be trying to argue. Your thesis can be a few sentences long, but should not be longer than a paragraph. Do not begin to state evidence or use examples in your thesis paragraph.

A Thesis Helps You and Your Reader

Your blueprint for writing:

• Helps you determine your focus and clarify your ideas.
• Provides a "hook" on which you can "hang" your topic sentences.
• Can (and should) be revised as you further refine your evidence and arguments. New evidence often requires you to change your thesis.
• Gives your paper a unified structure and point.

Your reader’s blueprint for reading:

• Serves as a "map" to follow through your paper.
• Keeps the reader focused on your argument.
• Signals to the reader your main points.
• Engages the reader in your argument.

Tips for Writing a Good Thesis

• Find a Focus: Choose a thesis that explores an aspect of your topic that is important to you, or that allows you to say something new about your topic. For example, if your paper topic asks you to analyze women’s domestic labor during the early nineteenth century, you might decide to focus on the products they made from scratch at home.
• Look for Pattern: After determining a general focus, go back and look more closely at your evidence. As you re-examine your evidence and identify patterns, you will develop your argument and some conclusions. For example, you might find that as industrialization increased, women made fewer textiles at home, but retained their butter and soap making tasks.

Strategies for Developing a Thesis Statement

Idea 1. If your paper assignment asks you to answer a specific question, turn the question into an assertion and give reasons for your opinion.

Assignment: How did domestic labor change between 1820 and 1860? Why were the changes in their work important for the growth of the United States?

Beginning thesis: Between 1820 and 1860 women's domestic labor changed as women stopped producing home-made fabric, although they continued to sew their families' clothes, as well as to produce butter and soap. With the cash women earned from the sale of their butter and soap they purchased ready-made cloth, which in turn, helped increase industrial production in the United States before the Civil War.

Idea 2. Write a sentence that summarizes the main idea of the essay you plan to write.

Main Idea: Women's labor in their homes during the first half of the nineteenth century contributed to the growth of the national economy.

Idea 3. Spend time "mulling over" your topic. Make a list of the ideas you want to include in the essay, then think about how to group them under several different headings. Often, you will see an organizational plan emerge from the sorting process.

Idea 4. Use a formula to develop a working thesis statement (which you will need to revise later). Here are a few examples:

• 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 ______.

These formulas share two characteristics all thesis statements should have: they state an argument and they reveal how you will make that argument. They are not specific enough, however, and require more work.

As you work on your essay, your ideas will change and so will your thesis. Here are examples of weak and strong thesis statements.

• Unspecific thesis: "Eleanor Roosevelt was a strong leader as First Lady."  This thesis lacks an argument. Why was Eleanor Roosevelt a strong leader?
• Specific thesis: "Eleanor Roosevelt recreated the role of the First Lady by her active political leadership in the Democratic Party, by lobbying for national legislation, and by fostering women’s leadership in the Democratic Party."  The second thesis has an argument: Eleanor Roosevelt "recreated" the position of First Lady, and a three-part structure with which to demonstrate just how she remade the job.
• Unspecific thesis: "At the end of the nineteenth century French women lawyers experienced difficulty when they attempted to enter the legal profession."  No historian could argue with this general statement and uninteresting thesis.
• Specific thesis: "At the end of the nineteenth century French women lawyers experienced misogynist attacks from male lawyers when they attempted to enter the legal profession because male lawyers wanted to keep women out of judgeships."  This thesis statement asserts that French male lawyers attacked French women lawyers because they feared women as judges, an intriguing and controversial point.

Making an Argument – Every Thesis Deserves Its Day in Court

You are the best (and only!) advocate for your thesis. Your thesis is defenseless without you to prove that its argument holds up under scrutiny. The jury (i.e., your reader) will expect you, as a good lawyer, to provide evidence to prove your thesis. To prove thesis statements on historical topics, what evidence can an able young lawyer use?

• Primary sources: letters, diaries, government documents, an organization’s meeting minutes, newspapers.
• Secondary sources: articles and books from your class that explain and interpret the historical event or person you are writing about, lecture notes, films or documentaries.

How can you use this evidence?

• Make sure the examples you select from your available evidence address your thesis.
• Use evidence that your reader will believe is credible. This means sifting and sorting your sources, looking for the clearest and fairest. Be sure to identify the biases and shortcomings of each piece of evidence for your reader.
• Use evidence to avoid generalizations. If you assert that all women have been oppressed, what evidence can you use to support this? Using evidence works to check over-general statements.
• Use evidence to address an opposing point of view. How do your sources give examples that refute another historian’s interpretation?

Remember -- if in doubt, talk to your instructor.
