Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

  • In this essay, I argue ____, using ______ to assert _____.
  • While scholars have often argued ______, I argue______, because_______.
  • Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

Learning Objectives

  • Define what an argument is.
  • Discuss uses of ethos, pathos, and logos.
  • Identify the argument structure of claim, evidence, and warrant.
  • Explore effective language.

You may be wondering, “What exactly is an argument? Haven’t I already decided on my main argument and topic?”

An argument is a series of statements in support of a claim, assertion, or proposition. So far, we’ve discussed thesis statements as the main argumentative through-line for a speech—it’s what you want to inform, persuade, or entertain the audience about.

Your thesis statement, however, is just one component of an argument, i.e. “here’s what I want to inform you about / persuade you to consider.” It is the main claim of your speech. Your task is to prove the reliability of that claim (with evidence) and demonstrate, through the body of the speech, how or why that information should matter to the audience. In this chapter, we will fill in the other structural components of an argument to make sure that your thesis statement has adequate support and proof. We’ll also outline the importance of language and tips to guarantee that your language increases the effective presentation of your argument.

An Overview of Arguments

It may be tempting to view arguments as only relevant to persuasion or persuasive speeches. After all, we commonly think of arguments as occurring between different perspectives or viewpoints with the goal of changing someone’s mind. Arguments are important when persuading, but you should have clear evidence and explanations for any type of information sharing.

All speech types require proof to demonstrate the reliability of their claims. Remember, when you speak, you are being an advocate and selecting information that you find relevant to your audience, so arguments are necessary to, at a bare minimum, build in details about the topic’s importance.

With speeches that primarily inform, a sound argument demonstrates the relevance and significance of the topic for your audience. In other words, “this is important information because…” or “here’s why you should care about this.” If you are giving a ceremonial speech, you should provide examples of your insights. In a speech of introduction, for example, you may claim that the speaker has expertise, but you should also provide evidence of their previous accomplishments and demonstrate why those accomplishments are significant.

For each speech type, a well-crafted speech will have multiple arguments throughout. Yes, your thesis statement is central to speech, and your content should be crafted around that idea – you will use your entire speech to prove the reliability of that statement. You will also have internal arguments, i.e. your speech’s main points or the “meat” of your speech.

All speech types require arguments, and all arguments use the rhetorical appeals of ethos, pathos, and logos to elicit a particular feeling or response from your audience.

Ethos , or establishing your credibility as a speaker, is necessary for any speech. If you’re informing the audience about a key topic, they need to know that you’re a trustworthy and reliable speaker. A key way to prove that credibility is through crafting arguments that are equally credible. Using reliable and well-tested evidence is one way to establish ethos.

Using reason or logic, otherwise known as logos , is also a key rhetorical appeal. By using logos, you can select logical evidence that is well-reasoned, particularly when you’re informing or persuading.

Pathos , or emotional appeals, allows you to embed evidence or explanations that pull on your audience’s heartstrings or other feelings and values. Pathos is common in ceremonial speeches, particularly speeches that eulogize or celebrate a special occasion.

All three rhetorical appeals are important mechanisms to motivate your audience to listen or act. All three should be done ethically and with the speech context and audience in mind.

Regardless of which rhetorical proof you use, your arguments should be well-researched and well-structured. Below, we explore the structure of an argument in more detail.

The Structur e : Claim, Evidence, Warrant

Arguments have the following basic structure (see Figure 19.1):

  • Claim: the main proposition crafted as a declarative statement.
  • Evidence: the support or proof for the claim.
  • Warrant: the connection between the evidence and the claim.

Each component of the structure is necessary to formulate a compelling argument.

The Toulmin Model

British Philosopher, Stephen Toulmin, created the “Toulmin Model” – a model that describes the structure of an argument or method of reasoning. Claim, evidence, and warrant are, if done well, necessary to create a good argument (O’Connor, 1958).

Visual layout of claim, evidence, and warrant

Evidence and warrants are the specifics that make your ideas, arguments, assertions, points, or concepts real and concrete by relating the information to your audience. Not all audiences are compelled by the same evidence, for example, so creating a well-structured argument also means being responsive to audiences.

Consider going to lunch with a friend. Your friend suggests a restaurant that you have not heard of, so you request some additional information, proof, or evidence of their choice. We could map the argument like this:

  • Claim: “Let’s go to Jack’s Shack for lunch.”
  • Evidence: “I have been there a few times and they have good servers.”

So far, your friend is highlighting service as the evidence to support their claim that Jack’s Shack is a good choice for lunch. However, the warrant is still missing. For a warrant, they need to demonstrate why good service is sufficient proof to support their claim. Remember that the warrant is the connection. For example:

  • Warrant: “You were a server, so I know that you really appreciate good service. I have never had a bad experience at Jack’s Shack, so I am confident that it’s a good lunch choice for both of us.”

In this case, they do a good job of both connecting the evidence to the claim and connecting the argument to their audience – you! They have selected evidence based on your previous experience as a server (likely in hopes to win you over to their claim!).

Using “claim, evidence, and warrant” can assist you in verifying that all parts of the argumentative structure are present. Below, we dive deeper into each category.

A claim is a declarative statement or assertion—it is something that you want your audience to accept or know. Like we’ve mentioned, your thesis statement is a key claim in your speech because it’s the main argument that you’re asking the audience to consider.

Different claims serve different purposes. Depending on the purpose of the argument, claims can be factual, opinionated, or informative. Some claims, for example, may be overtly persuading the audience to change their mind about a controversial issue, i.e. “you should support this local policy initiative.”

Alternatively, a claim may develop the significance of a topic (i.e. “this is why you should care about this information”) or highlight a key informative component about a person, place, or thing (“Hillary Clinton had an intriguing upbringing”). You might, for example, write a speech that informs the audience about college textbook affordability. Your working thesis might read, “Universities are developing textbook affordability initiatives.” Your next step would be to develop main points and locate evidence that supports your claim.

It’s important to develop confidence around writing and identifying your claims. Identifying your main ideas will allow you to then identify evidence in support of those declarative statements. If you aren’t confident about what claims you’re making, it will be difficult to identify the evidence in support of that idea, and your argument won’t be structurally complete. Remember that your thesis statement, your main claim, but you likely have claims throughout your speech (like your main points).

Evidence is the proof or support for your claim. It answers the question, “how do I know this is true?” With any type of evidence, there are three overarching considerations.

First, is this the most timely and relevant type of support for my claim? If your evidence isn’t timely (or has been disproven), it may drastically influence the credibility of your claim.

Second, is this evidence relatable and clear for my audience? Your audience should be able to understand the evidence, including any references or ideas within your information. Have you ever heard a joke or insight about a television show that you’ve never seen? If so, understanding the joke can be difficult. The same is true for your audience, so stay focused on their knowledge base and level of understanding.

Third, did I cherry-pick? Avoid cherry-picking evidence to support your claims. While we’ve discussed claims first, it’s important to arrive at a claim after seeing all the evidence (i.e. doing the research). Rather than finding evidence to fit your idea (cherry-picking), the evidence should help you arrive at the appropriate claim. Cherry-picking evidence can reduce your ethos and weakened your argument.

With these insights in mind, we will introduce you to five evidence types : examples, narratives, facts, statistics, and testimony. Each provides a different type of support, and it’s suggested that you integrate a variety of different evidence types. Understanding the different types of evidence will assist as you work to structure arguments and select support that best fits the goal of your speech.

Examples are specific instances that illuminate a concept. They are designed to give audiences a reference point. An example must be quickly understandable—something the audience can pull out of their memory or experience quickly.

Evidence by example would look like this:

Claim: Textbook affordability initiatives are assisting universities in implementing reputable, affordable textbooks.

Evidence : Ohio has implemented a textbook affordability initiative, the Open Ed Collaborative, to alleviate the financial strain for students (Jaggers, Rivera, Akani, 2019).

Ohio’s affordability initiative functions as evidence by example. This example assists in demonstrating that such initiatives have been successfully implemented. Without providing an example, your audience may be skeptical about the feasibility of your claim.

Examples can be drawn directly from experience, i.e. this is a real example, or an example can be hypothetical where audiences are asked to consider potential scenarios.

Narratives are stories that clarify, dramatize, and emphasize ideas. They have, if done well, strong emotional power (or pathos). While there is no universal type of narrative, a good story often draws the audience in by identifying characters and resolving a plot issue. Narratives can be personal or historical.

Person narratives are powerful tools to relate to your audience and embed a story about your experience with the topic. As evidence, they allow you to say, “I experienced or saw this thing first hand.” As the speaker, using your own experience as evidence can draw the audience in and help them understand why you’re invested in the topic. Of course, personal narratives must be true. Telling an untrue personal narrative may negatively influence your ethos for an audience.

Historical narratives (sometimes called documented narratives) are stories about a past person, place, or thing. They have power because they can prove and clarify an idea by using a common form— the story. By “historical” we do not mean that the story refers to something that happened many years ago, only that it has happened in the past and there were witnesses to validate the happening. Historical narratives are common in informative speeches.

Facts are observations, verified by multiple credible sources, that are true or false. The National Center for Science Education (2008) defines fact as:

an observation that has been repeatedly confirmed an . . . is accepted as ‘true.’ Truth in science, however, is never final and what is accepted as a fact today may be modified or even discarded tomorrow.

“The sun is a star” is an example of a fact. It’s been observed and verified based on current scientific understanding and categorization; however, future technology may update or disprove that fact.

In our modern information age, we recommend “fact-checking a fact” because misinformation can be presented as truth. This means verifying all facts through credible research (revisit the earlier chapter on research). Avoid taking factual information for granted and make sure that the evidence comes from reputable sources that are up-to-date.

S tatistics are the collection, analysis, comparison, and interpretation of numerical data. As evidence, they are useful in summarizing complex information, quantifying, or making comparisons. Statistics are powerful pieces of evidence because numbers appear straightforward. Numbers provide evidence that quantifies, and statistics can be helpful to clarify a concept or highlighting the depth of a problem.

You may be wondering, “What does this actually mean ?” (excuse our statistical humor). We often know a statistic when we find one, but it can be tricky to understand how a statistic was derived.

Averages and percentages are two common deployments of statistical evidence.

An “ a verage ” can be statistically misleading, but it often refers to the mean of a data set. You can determine the mean (or average) by adding up the figures and dividing by the number of figures present. If you’re giving a speech on climate change, you might note that, in 2015, the average summer temperature was 97 degrees while, in 1985, it was just 92 degrees.

When using statistics, comparisons can help translate the statistic for an audience. In the example above, 97 degrees may seem hot, but the audience has nothing to compare that statistic to. The 30-year comparison assists in demonstrating a change in temperature.

A percentag e expresses a proportion of out 100. For example, you might argue that “textbook costs have risen more than 1000% since 1977” (Popken, 2015). By using a statistical percentage, 1000% sounds pretty substantial. It may be important, however, to accompany your percentage with a comparison to assist the audience in understanding that “This is 3 times higher than the normal rate of inflation” (UTA Libraries). You might also clarify that “college textbooks have risen more than any other college-related cost” (Bureau of Labor Statistics, 2016).

You are responsible for the statistical information that you deploy. It’s all too common for us as information consumers to grab a quick statistic that sounds appealing, but that information may not be reliable.

Be aware of three major statistical issues: small samples, unrepresentative samples, and correlation as causation. In a small sample, an argument is being made from too few examples. In an unrepresentative sample, a conclusion is based on surveys of people who do not represent, or resemble, the ones to whom the conclusion is being applied. Finally, it’s common to conflate correlation as causation. In statistics, a correlation refers to the relationship between two variables while causation means that one variable resulted from the other. Be careful not to assume that a correlation means that something has caused the second.

A few other statistical tips:

  • Use statistics as support, not as a main point. The audience may cringe or tune you out for saying, “Now I’d like to give you some statistics about the problem of gangs in our part of the state.” That sounds as exciting as reading the telephone book! Use the statistics to support an argument.
  • Regarding sources, depend on the reliable ones. Use the earlier chapter on research as a guide to criticizing and evaluating credible sources.
  • Do not overuse statistics. While there is no hard and fast rule on how many to use, there are other good supporting materials and you would not want to depend on statistics alone. You want to choose the statistics and numerical data that will strengthen your argument the most and drive your point home. Statistics can have emotional power as well as probative value if used sparingly.
  • Explain your statistics as needed, but do not make your speech a statistics lesson. If you say, “My blog has 500 subscribers” to a group of people who know little about blogs, that might sound impressive, but is it? You can also provide a story of an individual, and then tie the individual into the statistic. After telling a story of the daily struggles of a young mother with multiple sclerosis, you could follow up with “This is just one story in the 400,000 people who suffer from MS in the United States today, according to National MS Society.”

Testimony is the words of others. As evidence, testimony can be valuable to gain insight into an expert or a peer’s opinion, experience, or expertise about a topic. Testimony can provide an audience with a relevant perspective that the speaker isn’t able to provide. We’ll discuss two types of testimony: expert and non-expert.

Expert Testimony

What is an expert? An expert is someone with recognized credentials, knowledge, education, and/or experience in a subject. To quote an expert on expertise, “To be an expert, someone needs to have considerable knowledge on a topic or considerable skill in accomplishing something” (Weinstein, 1993).

A campus bookstore manager could provide necessary testimony on the changing affordability of textbooks over time, for example. As someone working with instructors, students, and publishers, the manager would likely have an insight and a perspective that would be difficult to capture otherwise. They would provide unique and credible evidence.

In using expert testimony, you should follow these guidelines:

  • Use the expert’s testimony in their relevant field. A person may have a Nobel Prize in economics, but that does not make them an expert in biology.
  • Provide at least some of the expert’s relevant credentials.
  • If you interviewed the expert yourself, make that clear in the speech also. “When I spoke with Dr. Mary Thompson, principal of Park Lake High School, on October 12, she informed me that . . .”

Expert testimony is one of your strongest supporting materials to prove your arguments. When integrating their testimony as evidence, make sure their testimony clearly supports your claim (rather than an interesting idea on the topic that is tangential to your assertions).

Non-Expert/Peer Testimony

Any quotation from a friend, family member, or classmate about an incident or topic would be peer testimony. It is useful in helping the audience understand a topic from a personal point of view. For example, you may draw on testimony from a campus student who was unable to afford their campus textbooks. While they may lack formalized expertise in textbook affordability, their testimony might demonstrate how the high cost limited their engagement with the class. Their perspective and insight would be valuable for an audience to hear.

The third component of any argument is the warrant. Warrants connect the evidence and the claim. They often answer the question, “what does this mean?” Warrants are an important component of a complete argument because they:

  • Highlight the significance of the evidence;
  • Detail how the evidence supports the claims;
  • Outline the relevance of the claim and evidence to the audience.

For example, consider the claim that “communication studies provide necessary skills to land you a job.” To support that claim, you might locate a statistic and argue that, “The New York Times had a recent article stating that 80% of jobs want good critical thinking and interpersonal skills.” It’s unclear, however, how a communication studies major would prepare someone to fulfill those needs. To complete the argument, you could include a warrant that explains, “communication studies classes facilitate interpersonal skills and work to embed critical thinking activities throughout the curriculum.” You are connecting the job skills (critical thinking) from the evidence to the discipline (communication studies) from your claim.

Despite their importance, warrants are often excluded from arguments. As speechwriters and researchers, we spend lots of time with our information and evidence, and we take for granted what we know. If you are familiar with communication studies, the connection between the New York Times statistic referenced above and the assertion that communication studies provides necessary job skills may seem obvious. For an unfamiliar audience, the warrant provides more explanation and legitimacy to the evidence.

We know what you’re thinking: “Really? Do I always need an explicit warrant?”

Some warrants are indeed inferred , meaning that we often recognize the underlying warrant without it being explicitly stated. For example, I might say, “The baking time for my cookies was too hot. The cookies burned.” In this statement, I’m claiming that the temperature is too hot and using burnt cookies as the evidence. We could reasonably infer the warrant, i.e. “burnt cookies are a sign that they were in the oven for too long.”

Inferred warrants are common in everyday arguments and conversations; however, in a formal speech, having a clear warrant will increase the clarity of your argument. If you decide that no explicit warrant is needed, it’s still necessary to ask, “what does this argument mean for my thesis? What does it mean for my audience?” Your goal is to keep as many audience members listening as possible, and warrants allow you to think critically about the information that you’re presenting to that audience.

When writing warrants, keep the following insights in mind:

  • Avoid exaggerating your evidence, and make sure your warrant honors what the evidence is capable of supporting;
  • Center your thesis statement. Remember that your thesis statement, as your main argument, should be the primary focus when you’re explaining and warranting your evidence.
  • A good warrant should be crafted with your content and context in mind. As you work on warrants, ask, “why is this claim/evidence important here? For this argument? Now? For this audience?”
  • Say it with us: ethos, pathos, and logos! Warrants can help clarify the goal of your argument. What appeal are you using? Can the warrant amplify that appeal?

Now that you have a better understanding of each component of an argument, let’s conclude this section with a few complete examples.

Claim : The Iowa Wildcats will win the championship. Evidence: In 2019, the National Sporting Association found that the Wildcats had the most consistent and well-rounded coaching staff. Referees of the game agreed, and also praised the players’ ability for high scoring. Warrant: Good coaching and high scoring are probable indicators of past champions and, given this year’s findings, the Wildcats are on mark to win it all.

Here’s an example with a more general approach to track the potential avenues for evidence:

Claim: Sally Smith will win the presidential election. Evidence: [select evidence that highlights their probable win, including: they’ve won the most primaries; they won the Iowa caucus; they’re doing well in swing states; they have raised all the money; they have the most organized campaign.” Warrant: [based on your evidence selection, you can warrant why that evidence supports a presidential win].

Using Language Effectively

Claim, evidence, and warrant are useful categories when constructing or identifying a well-reasoned argument. However, a speech is much more than this simple structure over and over (how boring, huh?).

When we craft arguments, it’s tempting to view our audience as logic-seekers who rely solely on rationality, but that’s not true. Instead, Walter Fisher (1984) argues that humans are storytellers, and we make sense of the world through good stories. A good speech integrates argumentative components while telling a compelling story about your argument to the audience. A key piece of that story is how you craft the language—language aids in telling an effective story.

Language: What Do We Mean?

Language is any formal system of gestures, signs, sounds, and symbols used or conceived as a means of communicating thought, either through written, enacted, or spoken means. Linguists believe there are far more than 6,900 languages and distinct dialects spoken in the world today (Anderson, 2012). Despite being a formal system, language results in different interpretations and meanings for different audiences.

It is helpful for public speakers to keep this in mind, especially regarding denotative and connotative meaning. Wrench, Goding, Johnson, and Attias (2011) use this example to explain the difference:

When we hear or use the word “blue,” we may be referring to a portion of the visual spectrum dominated by energy with a wave-length of roughly 440–490 nanometers. You could also say that the color in question is an equal mixture of both red and green light. While both of these are technically correct ways to interpret the word “blue,” we’re pretty sure that neither of these definitions is how you thought about the word. When hearing the word “blue,” you may have thought of your favorite color, the color of the sky on a spring day, or the color of a really ugly car you saw in the parking lot. When people think about language, there are two different types of meanings that people must be aware of: denotative and connotative. (p. 407)

Denotative meaning is the specific meaning associated with a word. We sometimes refer to denotative meanings as dictionary definitions. The scientific definitions provided above for the word “blue” are examples of definitions that might be found in a dictionary. Connotative meaning is the idea suggested by or associated with a word at a cultural or personal level. In addition to the examples above, the word “blue” can evoke many other ideas:

  • State of depression (feeling blue)
  • Indication of winning (a blue ribbon)
  • Side during the Civil War (blues vs. grays)
  • Sudden event (out of the blue)
  • States that lean toward the Democratic Party in their voting
  • A slang expression for obscenity (blue comedy)

Given these differences, the language you select may have different interpretations and lead to different perspectives. As a speechwriter (and communicator), being aware of different interpretations can allow you to select language that is the most effective for your speaking context and audience.

Using Language to Craft Your Argument

Have you ever called someone a “wordsmith?” If so, you’re likely complimenting their masterful application of language. Language is not just something we use; it is part of who we are and how we think. As such, language can assist in clarifying your content and creating an effective message.

Achieve Clarity

Clear language is powerful language. If you are not clear, specific, precise, detailed, and sensory with your language, you won’t have to worry about being emotional or persuasive, because you won’t be understood. The goal of clarity is to reduce abstraction; clarity will allow your audience to more effectively track your argument and insight, especially because they only have one chance to listen.

Concreteness aids clarity. We usually think of concreteness as the opposite of abstraction. Language that evokes many different visual images in the minds of your audience is abstract language. Unfortunately, when abstract language is used, the images evoked might not be the ones you really want to evoke. Instead, work to be concrete, detailed, and specific. “Pity,” for example, is a bit abstract. How might you describe pity by using more concrete words?

Clear descriptions or definitions can aid in concreteness and clarity.

To define means to set limits on something; defining a word is setting limits on what it means, how the audience should think about the word, and/or how you will use it. We know there are denotative and connotative definitions or meanings for words, which we usually think of as objective and subjective responses to words. You only need to define words that would be unfamiliar to the audience or words that you want to use in a specialized way.

Describing is also helpful in clarifying abstraction. The key to description is to think in terms of the five senses: sight (visual:  how does the thing look in terms of color, size, shape); hearing (auditory: volume, musical qualities); taste (gustatory: sweet, bitter, salty, sour, gritty, smooth, chewy); smell (olfactory: sweet, rancid, fragrant, aromatic, musky); and feel (tactile: rough, silky, nubby, scratchy).

If you were, for example, talking about your dog, concrete and detailed language could assist in “bring your dog to life,” so to speak, in the moment.

Sharpei-mix dog in grass

  • Boring and abstract: My dog is pretty great. He is well-behaved, cute, and is friendly to all of our neighbors. I get a lot of compliments about him, and I really enjoy hanging out with him outside in the summer.
  • Concrete and descriptive: Buckley, my golden-brown Sharpei mix, is a one-of-a-kind hound. Through positive treat reinforcement, he learned to sit, shake, and lay down within one month. He will also give kisses with his large and wrinkly snout. He greets passing neighbors with a smile and enjoys Midwest sunbathing on our back deck in the 70-degree heat.

 Doesn’t the second description do the image more justice ? Being concrete and descriptive paints a picture for the audience and can increase your warrant’s efficacy. Being descriptive, however, doesn’t mean adding more words. In fact, you should aim to “reduce language clutter.” Your descriptions should still be purposeful and important.

Be Effective

Language achieves effectiveness by communicating the right message to the audience. Clarity contributes to effectiveness, but effectiveness also includes using familiar and interesting language.

Familiar language is language that your audience is accustomed to hearing and experiencing. Different communities and audiences use language differently. If you are part of an organization, team, or volunteer group, there may be language that is specific and commonly used in those circles. We call that language jargon , or specific, technical language that is used in a given community. If you were speaking to that community, drawing on those references would be appropriate because they would be familiar to that audience. For other audiences, drawing on jargon would be ineffective and either fail to communicate an idea to the audience or implicitly community that you haven’t translated your message well (reducing your ethos).

In addition to using familiar language, draw on language that’s accurate and interesting. This is difficult, we’ll admit it! But in a speech, your words are a key component of keeping the audience motivated to listen, so interesting language can peak and maintain audience interest.

Active language is interesting language. Active voice , when the subject in a sentence performs the action, can assist in having active and engaging word choices. An active sentence would read, “humans caused climate change” as opposed to a passive approach of, “climate change was caused by humans.” Place subjects at the forefront. A helpful resource on active voice can be found here.

You must, however, be reflexive in the language process.

Practicing Reflexivity

Language reflects our beliefs, attitudes, and values – words are the mechanism we use to communicate our ideas or insights. As we learned earlier in this book, communication both creates and is created by culture. When we select language, we are also representing and creating ideas and cultures – language has a lot of power.

To that end, language should be a means of inclusion and identification, rather than exclusion.

You might be thinking, “Well I am always inclusive in my language,” or “I’d never intentionally use language that’s not inclusive.” We understand, but intention is less important than effect.

Consider the term “millennial”— a categorization that refers to a particular age group. It can be useful to categorize different generations, particularly from a historical and contemporary perspective. However, people often argue that “millennials are the laziest generation” or “millennials don’t know hard work!” In these examples, the intention may be descriptive, but they are selecting language that perpetuates unfair and biased assumptions about millions of people. The language is disempowering (and the evidence, when present, is weak).

Language assists us in categorizing or understanding different cultures, ideas, or people; we rely on language to sort information and differentiate ourselves. In turn, language influences our perceptions, even in unconscious and biased ways.

The key is to practice reflexivity about language choices. Language isn’t perfect, so thinking reflexively about language will take time and practice.

For example, if you were crafting a hypothetical example about an experience in health care, you might open with a hypothetical example: “Imagine sitting for hours in the waiting room with no relief. Fidgeting and in pain, you feel hopeless and forgotten within the system. Finally, you’re greeted by the doctor and he escorts you to a procedure room.” It’s a great story and there is vivid and clear language. But are there any changes that you’d make to the language used?

Remember that this is a hypothetical example. Using reflexive thinking, we might question the use of “he” to describe the doctor. Are there doctors that are a “he”? Certainly. Are all doctors a “he”? Certainly not. It’s important to question how “he” gets generalized to stand-in for doctors or how we may assume that all credible doctors are men.

Practicing reflexivity means questioning the assumptions present in our language choices (like police men rather than police officers). Continue to be conscious of what language you draw on to describe certain people, places, or ideas. If you aren’t sure what language choices are best to describe a group, ask; listen, and don’t assume.

In this chapter, we discussed crafting complete, well-reasoned arguments. Claim, evidence, and warrant are helpful structural components when crafting arguments. Remember, too, that language plays a central role in telling a compelling story.

A series of statements in support of a claim, assertion, or proposition

speaker credibility

Appeals to reason or logic

Appeals to emotion

a declarative statement or assertion

proof or support for your claim

specific instances that illuminate a concept

stories that clarify, dramatize, and emphasize ideas

the collection, analysis, comparison, and interpretation of numerical data

the words of others

Warrants connect the evidence and the claim

we often recognize the underlying warrant without it being explicitly stated

the specific meaning associated with a word

the idea suggested by or associated with a word at a cultural or personal level

Setting limits on what it means, how the audience should think about the word, and/or how you will use it

specific, technical language that is used in a given community.

Developing a Thesis Statement

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

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

What is a thesis statement?

A thesis statement . . .

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

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

Identify a topic

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

Consider what your assignment asks you to do

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

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

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

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

Sample assignment 2

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

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

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

Developing a Thesis Statement–Additional information

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

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

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

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

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

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

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

Derive a main point from topic

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

Look for patterns in your evidence

Compose a purpose statement.

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

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

Possible conclusion:

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

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.
  • The simile compares Simoisius to a tree, which is a peaceful, natural image.
  • The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

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

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

Derive purpose statement from topic

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

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

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

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

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

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

Compose a draft thesis statement

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

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

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

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

Question-to-Assertion

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refine and polish the thesis statement

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

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

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

Sample Assignment

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

  • Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.
Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.
Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.
While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.
While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

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

Complete the final thesis statement

The bottom line.

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

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

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

Thesis Statements

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.

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.

11.2 Persuasive Speaking

Learning objectives.

  • Explain how claims, evidence, and warrants function to create an argument.
  • Identify strategies for choosing a persuasive speech topic.
  • Identify strategies for adapting a persuasive speech based on an audience’s orientation to the proposition.
  • Distinguish among propositions of fact, value, and policy.
  • Choose an organizational pattern that is fitting for a persuasive speech topic.

We produce and receive persuasive messages daily, but we don’t often stop to think about how we make the arguments we do or the quality of the arguments that we receive. In this section, we’ll learn the components of an argument, how to choose a good persuasive speech topic, and how to adapt and organize a persuasive message.

Foundation of Persuasion

Persuasive speaking seeks to influence the beliefs, attitudes, values, or behaviors of audience members. In order to persuade, a speaker has to construct arguments that appeal to audience members. Arguments form around three components: claim, evidence, and warrant. The claim is the statement that will be supported by evidence. Your thesis statement is the overarching claim for your speech, but you will make other claims within the speech to support the larger thesis. Evidence , also called grounds, supports the claim. The main points of your persuasive speech and the supporting material you include serve as evidence. For example, a speaker may make the following claim: “There should be a national law against texting while driving.” The speaker could then support the claim by providing the following evidence: “Research from the US Department of Transportation has found that texting while driving creates a crash risk that is twenty-three times worse than driving while not distracted.” The warrant is the underlying justification that connects the claim and the evidence. One warrant for the claim and evidence cited in this example is that the US Department of Transportation is an institution that funds research conducted by credible experts. An additional and more implicit warrant is that people shouldn’t do things they know are unsafe.

The quality of your evidence often impacts the strength of your warrant, and some warrants are stronger than others. A speaker could also provide evidence to support their claim advocating for a national ban on texting and driving by saying, “I have personally seen people almost wreck while trying to text.” While this type of evidence can also be persuasive, it provides a different type and strength of warrant since it is based on personal experience. In general, the anecdotal evidence from personal experience would be given a weaker warrant than the evidence from the national research report. The same process works in our legal system when a judge evaluates the connection between a claim and evidence. If someone steals my car, I could say to the police, “I’m pretty sure Mario did it because when I said hi to him on campus the other day, he didn’t say hi back, which proves he’s mad at me.” A judge faced with that evidence is unlikely to issue a warrant for Mario’s arrest. Fingerprint evidence from the steering wheel that has been matched with a suspect is much more likely to warrant arrest.

As you put together a persuasive argument, you act as the judge. You can evaluate arguments that you come across in your research by analyzing the connection (the warrant) between the claim and the evidence. If the warrant is strong, you may want to highlight that argument in your speech. You may also be able to point out a weak warrant in an argument that goes against your position, which you could then include in your speech. Every argument starts by putting together a claim and evidence, but arguments grow to include many interrelated units.

Choosing a Persuasive Speech Topic

As with any speech, topic selection is important and is influenced by many factors. Good persuasive speech topics are current, controversial, and have important implications for society. If your topic is currently being discussed on television, in newspapers, in the lounges in your dorm, or around your family’s dinner table, then it’s a current topic. A persuasive speech aimed at getting audience members to wear seat belts in cars wouldn’t have much current relevance, given that statistics consistently show that most people wear seat belts. Giving the same speech would have been much more timely in the 1970s when there was a huge movement to increase seat-belt use.

Many topics that are current are also controversial, which is what gets them attention by the media and citizens. Current and controversial topics will be more engaging for your audience. A persuasive speech to encourage audience members to donate blood or recycle wouldn’t be very controversial, since the benefits of both practices are widely agreed on. However, arguing that the restrictions on blood donation by men who have had sexual relations with men be lifted would be controversial. I must caution here that controversial is not the same as inflammatory. An inflammatory topic is one that evokes strong reactions from an audience for the sake of provoking a reaction. Being provocative for no good reason or choosing a topic that is extremist will damage your credibility and prevent you from achieving your speech goals.

You should also choose a topic that is important to you and to society as a whole. As we have already discussed in this book, our voices are powerful, as it is through communication that we participate and make change in society. Therefore we should take seriously opportunities to use our voices to speak publicly. Choosing a speech topic that has implications for society is probably a better application of your public speaking skills than choosing to persuade the audience that Lebron James is the best basketball player in the world or that Superman is a better hero than Spiderman. Although those topics may be very important to you, they don’t carry the same social weight as many other topics you could choose to discuss. Remember that speakers have ethical obligations to the audience and should take the opportunity to speak seriously.

You will also want to choose a topic that connects to your own interests and passions. If you are an education major, it might make more sense to do a persuasive speech about funding for public education than the death penalty. If there are hot-button issues for you that make you get fired up and veins bulge out in your neck, then it may be a good idea to avoid those when speaking in an academic or professional context.

11.2.1N

Choose a persuasive speech topic that you’re passionate about but still able to approach and deliver in an ethical manner.

Michael Vadon – Nigel Farage – CC BY-SA 2.0.

Choosing such topics may interfere with your ability to deliver a speech in a competent and ethical manner. You want to care about your topic, but you also want to be able to approach it in a way that’s going to make people want to listen to you. Most people tune out speakers they perceive to be too ideologically entrenched and write them off as extremists or zealots.

You also want to ensure that your topic is actually persuasive. Draft your thesis statement as an “I believe” statement so your stance on an issue is clear. Also, think of your main points as reasons to support your thesis. Students end up with speeches that aren’t very persuasive in nature if they don’t think of their main points as reasons. Identifying arguments that counter your thesis is also a good exercise to help ensure your topic is persuasive. If you can clearly and easily identify a competing thesis statement and supporting reasons, then your topic and approach are arguable.

Review of Tips for Choosing a Persuasive Speech Topic

  • Not current. People should use seat belts.
  • Current. People should not text while driving.
  • Not controversial. People should recycle.
  • Controversial. Recycling should be mandatory by law.
  • Not as impactful. Superman is the best superhero.
  • Impactful. Colleges and universities should adopt zero-tolerance bullying policies.
  • Unclear thesis. Homeschooling is common in the United States.
  • Clear, argumentative thesis with stance. Homeschooling does not provide the same benefits of traditional education and should be strictly monitored and limited.

Adapting Persuasive Messages

Competent speakers should consider their audience throughout the speech-making process. Given that persuasive messages seek to directly influence the audience in some way, audience adaptation becomes even more important. If possible, poll your audience to find out their orientation toward your thesis. I read my students’ thesis statements aloud and have the class indicate whether they agree with, disagree with, or are neutral in regards to the proposition. It is unlikely that you will have a homogenous audience, meaning that there will probably be some who agree, some who disagree, and some who are neutral. So you may employ all of the following strategies, in varying degrees, in your persuasive speech.

When you have audience members who already agree with your proposition, you should focus on intensifying their agreement. You can also assume that they have foundational background knowledge of the topic, which means you can take the time to inform them about lesser-known aspects of a topic or cause to further reinforce their agreement. Rather than move these audience members from disagreement to agreement, you can focus on moving them from agreement to action. Remember, calls to action should be as specific as possible to help you capitalize on audience members’ motivation in the moment so they are more likely to follow through on the action.

There are two main reasons audience members may be neutral in regards to your topic: (1) they are uninformed about the topic or (2) they do not think the topic affects them. In this case, you should focus on instilling a concern for the topic. Uninformed audiences may need background information before they can decide if they agree or disagree with your proposition. If the issue is familiar but audience members are neutral because they don’t see how the topic affects them, focus on getting the audience’s attention and demonstrating relevance. Remember that concrete and proxemic supporting materials will help an audience find relevance in a topic. Students who pick narrow or unfamiliar topics will have to work harder to persuade their audience, but neutral audiences often provide the most chance of achieving your speech goal since even a small change may move them into agreement.

When audience members disagree with your proposition, you should focus on changing their minds. To effectively persuade, you must be seen as a credible speaker. When an audience is hostile to your proposition, establishing credibility is even more important, as audience members may be quick to discount or discredit someone who doesn’t appear prepared or doesn’t present well-researched and supported information. Don’t give an audience a chance to write you off before you even get to share your best evidence. When facing a disagreeable audience, the goal should also be small change. You may not be able to switch someone’s position completely, but influencing him or her is still a success. Aside from establishing your credibility, you should also establish common ground with an audience.

11.2.2N

Build common ground with disagreeable audiences and acknowledge areas of disagreement.

Chris-Havard Berge – Shaking Hands – CC BY-NC 2.0.

Acknowledging areas of disagreement and logically refuting counterarguments in your speech is also a way to approach persuading an audience in disagreement, as it shows that you are open-minded enough to engage with other perspectives.

Determining Your Proposition

The proposition of your speech is the overall direction of the content and how that relates to the speech goal. A persuasive speech will fall primarily into one of three categories: propositions of fact, value, or policy. A speech may have elements of any of the three propositions, but you can usually determine the overall proposition of a speech from the specific purpose and thesis statements.

Propositions of fact focus on beliefs and try to establish that something “is or isn’t.” Propositions of value focus on persuading audience members that something is “good or bad,” “right or wrong,” or “desirable or undesirable.” Propositions of policy advocate that something “should or shouldn’t” be done. Since most persuasive speech topics can be approached as propositions of fact, value, or policy, it is a good idea to start thinking about what kind of proposition you want to make, as it will influence how you go about your research and writing. As you can see in the following example using the topic of global warming, the type of proposition changes the types of supporting materials you would need:

  • Proposition of fact. Global warming is caused by increased greenhouse gases related to human activity.
  • Proposition of value. America’s disproportionately large amount of pollution relative to other countries is wrong .
  • Proposition of policy. There should be stricter emission restrictions on individual cars.

To support propositions of fact, you would want to present a logical argument based on objective facts that can then be used to build persuasive arguments. Propositions of value may require you to appeal more to your audience’s emotions and cite expert and lay testimony. Persuasive speeches about policy usually require you to research existing and previous laws or procedures and determine if any relevant legislation or propositions are currently being considered.

“Getting Critical”

Persuasion and Masculinity

The traditional view of rhetoric that started in ancient Greece and still informs much of our views on persuasion today has been critiqued for containing Western and masculine biases. Traditional persuasion has been linked to Western and masculine values of domination, competition, and change, which have been critiqued as coercive and violent (Gearhart, 1979).

Communication scholars proposed an alternative to traditional persuasive rhetoric in the form of invitational rhetoric. Invitational rhetoric differs from a traditional view of persuasive rhetoric that “attempts to win over an opponent, or to advocate the correctness of a single position in a very complex issue” (Bone et al., 2008). Instead, invitational rhetoric proposes a model of reaching consensus through dialogue. The goal is to create a climate in which growth and change can occur but isn’t required for one person to “win” an argument over another. Each person in a communication situation is acknowledged to have a standpoint that is valid but can still be influenced through the offering of alternative perspectives and the invitation to engage with and discuss these standpoints (Ryan & Natalle, 2001). Safety, value, and freedom are three important parts of invitational rhetoric. Safety involves a feeling of security in which audience members and speakers feel like their ideas and contributions will not be denigrated. Value refers to the notion that each person in a communication encounter is worthy of recognition and that people are willing to step outside their own perspectives to better understand others. Last, freedom is present in communication when communicators do not limit the thinking or decisions of others, allowing all participants to speak up (Bone et al., 2008).

Invitational rhetoric doesn’t claim that all persuasive rhetoric is violent. Instead, it acknowledges that some persuasion is violent and that the connection between persuasion and violence is worth exploring. Invitational rhetoric has the potential to contribute to the civility of communication in our society. When we are civil, we are capable of engaging with and appreciating different perspectives while still understanding our own. People aren’t attacked or reviled because their views diverge from ours. Rather than reducing the world to “us against them, black or white, and right or wrong,” invitational rhetoric encourages us to acknowledge human perspectives in all their complexity (Bone et al., 2008).

  • What is your reaction to the claim that persuasion includes Western and masculine biases?
  • What are some strengths and weaknesses of the proposed alternatives to traditional persuasion?
  • In what situations might an invitational approach to persuasion be useful? In what situations might you want to rely on traditional models of persuasion?

Organizing a Persuasive Speech

We have already discussed several patterns for organizing your speech, but some organization strategies are specific to persuasive speaking. Some persuasive speech topics lend themselves to a topical organization pattern, which breaks the larger topic up into logical divisions. Earlier, in Chapter 9 “Preparing a Speech” , we discussed recency and primacy, and in this chapter we discussed adapting a persuasive speech based on the audience’s orientation toward the proposition. These concepts can be connected when organizing a persuasive speech topically. Primacy means putting your strongest information first and is based on the idea that audience members put more weight on what they hear first. This strategy can be especially useful when addressing an audience that disagrees with your proposition, as you can try to win them over early. Recency means putting your strongest information last to leave a powerful impression. This can be useful when you are building to a climax in your speech, specifically if you include a call to action.

11.2.3N

Putting your strongest argument last can help motivate an audience to action.

Celestine Chua – The Change – CC BY 2.0.

The problem-solution pattern is an organizational pattern that advocates for a particular approach to solve a problem. You would provide evidence to show that a problem exists and then propose a solution with additional evidence or reasoning to justify the course of action. One main point addressing the problem and one main point addressing the solution may be sufficient, but you are not limited to two. You could add a main point between the problem and solution that outlines other solutions that have failed. You can also combine the problem-solution pattern with the cause-effect pattern or expand the speech to fit with Monroe’s Motivated Sequence.

As was mentioned in Chapter 9 “Preparing a Speech” , the cause-effect pattern can be used for informative speaking when the relationship between the cause and effect is not contested. The pattern is more fitting for persuasive speeches when the relationship between the cause and effect is controversial or unclear. There are several ways to use causes and effects to structure a speech. You could have a two-point speech that argues from cause to effect or from effect to cause. You could also have more than one cause that lead to the same effect or a single cause that leads to multiple effects. The following are some examples of thesis statements that correspond to various organizational patterns. As you can see, the same general topic area, prison overcrowding, is used for each example. This illustrates the importance of considering your organizational options early in the speech-making process, since the pattern you choose will influence your researching and writing.

Persuasive Speech Thesis Statements by Organizational Pattern

  • Problem-solution. Prison overcrowding is a serious problem that we can solve by finding alternative rehabilitation for nonviolent offenders.
  • Problem–failed solution–proposed solution. Prison overcrowding is a serious problem that shouldn’t be solved by building more prisons; instead, we should support alternative rehabilitation for nonviolent offenders.
  • Cause-effect. Prisons are overcrowded with nonviolent offenders, which leads to lesser sentences for violent criminals.
  • Cause-cause-effect. State budgets are being slashed and prisons are overcrowded with nonviolent offenders, which leads to lesser sentences for violent criminals.
  • Cause-effect-effect. Prisons are overcrowded with nonviolent offenders, which leads to increased behavioral problems among inmates and lesser sentences for violent criminals.
  • Cause-effect-solution. Prisons are overcrowded with nonviolent offenders, which leads to lesser sentences for violent criminals; therefore we need to find alternative rehabilitation for nonviolent offenders.

Monroe’s Motivated Sequence is an organizational pattern designed for persuasive speaking that appeals to audience members’ needs and motivates them to action. If your persuasive speaking goals include a call to action, you may want to consider this organizational pattern. We already learned about the five steps of Monroe’s Motivated Sequence in Chapter 9 “Preparing a Speech” , but we will review them here with an example:

  • Hook the audience by making the topic relevant to them.
  • Imagine living a full life, retiring, and slipping into your golden years. As you get older you become more dependent on others and move into an assisted-living facility. Although you think life will be easier, things get worse as you experience abuse and mistreatment from the staff. You report the abuse to a nurse and wait, but nothing happens and the abuse continues. Elder abuse is a common occurrence, and unlike child abuse, there are no laws in our state that mandate complaints of elder abuse be reported or investigated.
  • Cite evidence to support the fact that the issue needs to be addressed.
  • According to the American Psychological Association, one to two million elderly US Americans have been abused by their caretakers. In our state, those in the medical, psychiatric, and social work field are required to report suspicion of child abuse but are not mandated to report suspicions of elder abuse.
  • Offer a solution and persuade the audience that it is feasible and well thought out.
  • There should be a federal law mandating that suspicion of elder abuse be reported and that all claims of elder abuse be investigated.
  • Take the audience beyond your solution and help them visualize the positive results of implementing it or the negative consequences of not.
  • Elderly people should not have to live in fear during their golden years. A mandatory reporting law for elderly abuse will help ensure that the voices of our elderly loved ones will be heard.
  • Call your audience to action by giving them concrete steps to follow to engage in a particular action or to change a thought or behavior.
  • I urge you to take action in two ways. First, raise awareness about this issue by talking to your own friends and family. Second, contact your representatives at the state and national level to let them know that elder abuse should be taken seriously and given the same level of importance as other forms of abuse. I brought cards with the contact information for our state and national representatives for this area. Please take one at the end of my speech. A short e-mail or phone call can help end the silence surrounding elder abuse.

Key Takeaways

  • Arguments are formed by making claims that are supported by evidence. The underlying justification that connects the claim and evidence is the warrant. Arguments can have strong or weak warrants, which will make them more or less persuasive.
  • Good persuasive speech topics are current, controversial (but not inflammatory), and important to the speaker and society.
  • When audience members agree with the proposal, focus on intensifying their agreement and moving them to action.
  • When audience members are neutral in regards to the proposition, provide background information to better inform them about the issue and present information that demonstrates the relevance of the topic to the audience.
  • When audience members disagree with the proposal, focus on establishing your credibility, build common ground with the audience, and incorporate counterarguments and refute them.
  • Propositions of fact focus on establishing that something “is or isn’t” or is “true or false.”
  • Propositions of value focus on persuading an audience that something is “good or bad,” “right or wrong,” or “desirable or undesirable.”
  • Propositions of policy advocate that something “should or shouldn’t” be done.
  • Persuasive speeches can be organized using the following patterns: problem-solution, cause-effect, cause-effect-solution, or Monroe’s Motivated Sequence.
  • Getting integrated: Give an example of persuasive messages that you might need to create in each of the following contexts: academic, professional, personal, and civic. Then do the same thing for persuasive messages you may receive.
  • To help ensure that your persuasive speech topic is persuasive and not informative, identify the claims, evidence, and warrants you may use in your argument. In addition, write a thesis statement that refutes your topic idea and identify evidence and warrants that could support that counterargument.
  • Determine if your speech is primarily a proposition of fact, value, or policy. How can you tell? Identify an organizational pattern that you think will work well for your speech topic, draft one sentence for each of your main points, and arrange them according to the pattern you chose.

  • Definition & Examples
  • When & How to Write a Thesis

I. What is a Thesis?

The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.

II. Examples of Theses

Here are a few examples of theses which may be found in the introductions of a variety of essays :

In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.

In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).

While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.

This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.

During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.

In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.

III. The Importance of Using a Thesis

Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.

IV. Examples of Theses in Literature

For examples of theses in literature, consider these thesis statements from essays about topics in literature:

In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.

This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.

In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.

In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.

John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.

This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.

V. Examples of Theses in Pop Culture

Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:

FOOD INC TEASER TRAILER - "More than a terrific movie -- it's an important movie." - Ent Weekly

America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.

The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.

Blackfish Official Trailer #1 (2013) - Documentary Movie HD

Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.

Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.

VI. Related Terms

Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:

Hypothesis:

Students skip school more often as summer vacation approaches.

This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.

Students skip school due to sickness, boredom with classes, and the urge to rebel.

This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.

Introduction

A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.

VII. Conclusion

Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

Module 3: Writing Essentials

Thesis statements, learning objectives.

  • Identify strong thesis statements

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

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

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

  • Social media harms the self-esteem of American pre-teen girls.
  • Social media can help connect researchers when they use hashtags to curate their work.
  • Social media tools are not tools for social movements, they are marketing tools.

A basic thesis sentence has two main parts:

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

Example Thesis Statements

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

Topic:  Regular exercise regime

Angle:  Leads to multiple benefits

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

Topic:  Adult college students

Angle:  Have different experiences

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

Topic:  Television viewing

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

When you read all of the thesis statements above, can you see areas where the writer could be more specific with their angle? The more specific you are with your topic and your claims, the more focused your essay will be for your reader.

Identifying the Thesis Statement

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

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

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

Thesis statements vary based on the rhetorical strategy of the essay. Thesis statements typically share the following characteristics:

  • presents the main idea
  • is one sentence
  • tells the reader what to expect
  • summarizes the essay topic
  • presents an argument
  • is written in the third person (does not include the “I” pronoun)

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

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

Writing a Thesis Statement

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

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

A good thesis statement will:

  • Consist of just one interesting idea
  • Be specific and written clearly
  • Have evidence to support it

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

Following are some typical thesis statements:

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

Thesis Problems to Avoid

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

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

Practice identifying strong thesis statements in the following interactive.

argument : in writing, the argument is the main stance, claim, or position that is supported with evidence

explicit thesis : a clear and direct statement of the writer’s claim

thesis statement : a statement of the topic of the piece of writing and the angle the writer has on that topic

14 Crafting a Thesis Statement

Learning Objectives

  • Craft a thesis statement that is clear, concise, and declarative.
  • Narrow your topic based on your thesis statement and consider the ways that your main points will support the thesis.

Crafting a Thesis Statement

A  thesis statement  is a short, declarative sentence that states the purpose, intent, or main idea of a speech. A strong, clear thesis statement is very valuable within an introduction because it lays out the basic goal of the entire speech. We strongly believe that it is worthwhile to invest some time in framing and writing a good thesis statement. You may even want to write your thesis statement before you even begin conducting research for your speech. While you may end up rewriting your thesis statement later, having a clear idea of your purpose, intent, or main idea before you start searching for research will help you focus on the most appropriate material. To help us understand thesis statements, we will first explore their basic functions and then discuss how to write a thesis statement.

Basic Functions of a Thesis Statement

A thesis statement helps your audience by letting them know, clearly and concisely, what you are going to talk about. A strong thesis statement will allow your reader to understand the central message of your speech. You will want to be as specific as possible. A thesis statement for informative speaking should be a declarative statement that is clear and concise; it will tell the audience what to expect in your speech. For persuasive speaking, a thesis statement should have a narrow focus and should be arguable, there must be an argument to explore within the speech. The exploration piece will come with research, but we will discuss that in the main points. For now, you will need to consider your specific purpose and how this relates directly to what you want to tell this audience. Remember, no matter if your general purpose is to inform or persuade, your thesis will be a declarative statement that reflects your purpose.

How to Write a Thesis Statement

Now that we’ve looked at why a thesis statement is crucial in a speech, let’s switch gears and talk about how we go about writing a solid thesis statement. A thesis statement is related to the general and specific purposes of a speech.

Once you have chosen your topic and determined your purpose, you will need to make sure your topic is narrow. One of the hardest parts of writing a thesis statement is narrowing a speech from a broad topic to one that can be easily covered during a five- to seven-minute speech. While five to seven minutes may sound like a long time for new public speakers, the time flies by very quickly when you are speaking. You can easily run out of time if your topic is too broad. To ascertain if your topic is narrow enough for a specific time frame, ask yourself three questions.

Is your speech topic a broad overgeneralization of a topic?

Overgeneralization occurs when we classify everyone in a specific group as having a specific characteristic. For example, a speaker’s thesis statement that “all members of the National Council of La Raza are militant” is an overgeneralization of all members of the organization. Furthermore, a speaker would have to correctly demonstrate that all members of the organization are militant for the thesis statement to be proven, which is a very difficult task since the National Council of La Raza consists of millions of Hispanic Americans. A more appropriate thesis related to this topic could be, “Since the creation of the National Council of La Raza [NCLR] in 1968, the NCLR has become increasingly militant in addressing the causes of Hispanics in the United States.”

Is your speech’s topic one clear topic or multiple topics?

A strong thesis statement consists of only a single topic. The following is an example of a thesis statement that contains too many topics: “Medical marijuana, prostitution, and Women’s Equal Rights Amendment should all be legalized in the United States.” Not only are all three fairly broad, but you also have three completely unrelated topics thrown into a single thesis statement. Instead of a thesis statement that has multiple topics, limit yourself to only one topic. Here’s an example of a thesis statement examining only one topic: Ratifying the Women’s Equal Rights Amendment as equal citizens under the United States law would protect women by requiring state and federal law to engage in equitable freedoms among the sexes.

Does the topic have direction?

If your basic topic is too broad, you will never have a solid thesis statement or a coherent speech. For example, if you start off with the topic “Barack Obama is a role model for everyone,” what do you mean by this statement? Do you think President Obama is a role model because of his dedication to civic service? Do you think he’s a role model because he’s a good basketball player? Do you think he’s a good role model because he’s an excellent public speaker? When your topic is too broad, almost anything can become part of the topic. This ultimately leads to a lack of direction and coherence within the speech itself. To make a cleaner topic, a speaker needs to narrow her or his topic to one specific area. For example, you may want to examine why President Obama is a good public speaker.

Put Your Topic into a Declarative Sentence

You wrote your general and specific purpose. Use this information to guide your thesis statement. If you wrote a clear purpose, it will be easy to turn this into a declarative statement.

General purpose: To inform

Specific purpose: To inform my audience about the lyricism of former President Barack Obama’s presentation skills.

Your thesis statement needs to be a declarative statement. This means it needs to actually state something. If a speaker says, “I am going to talk to you about the effects of social media,” this tells you nothing about the speech content. Are the effects positive? Are they negative? Are they both? We don’t know. This sentence is an announcement, not a thesis statement. A declarative statement clearly states the message of your speech.

For example, you could turn the topic of President Obama’s public speaking skills into the following sentence: “Because of his unique sense of lyricism and his well-developed presentational skills, President Barack Obama is a modern symbol of the power of public speaking.” Or you could state, “Socal media has both positive and negative effects on users.”

Adding your Argument, Viewpoint, or Opinion

If your topic is informative, your job is to make sure that the thesis statement is nonargumentative and focuses on facts. For example, in the preceding thesis statement, we have a couple of opinion-oriented terms that should be avoided for informative speeches: “unique sense,” “well-developed,” and “power.” All three of these terms are laced with an individual’s opinion, which is fine for a persuasive speech but not for an informative speech. For informative speeches, the goal of a thesis statement is to explain what the speech will be informing the audience about, not attempting to add the speaker’s opinion about the speech’s topic. For an informative speech, you could rewrite the thesis statement to read, “Barack Obama’s use of lyricism in his speech, ‘A World That Stands as One,’ delivered July 2008 in Berlin demonstrates exceptional use of rhetorical strategies. 

On the other hand, if your topic is persuasive, you want to make sure that your argument, viewpoint, or opinion is clearly indicated within the thesis statement. If you are going to argue that Barack Obama is a great speaker, then you should set up this argument within your thesis statement.

For example, you could turn the topic of President Obama’s public speaking skills into the following sentence: “Because of his unique sense of lyricism and his well-developed presentational skills, President Barack Obama is a modern symbol of the power of public speaking.” Once you have a clear topic sentence, you can start tweaking the thesis statement to help set up the purpose of your speech.

Thesis Checklist

Once you have written a first draft of your thesis statement, you’re probably going to end up revising your thesis statement a number of times prior to delivering your actual speech. A thesis statement is something that is constantly tweaked until the speech is given. As your speech develops, often your thesis will need to be rewritten to whatever direction the speech itself has taken. We often start with a speech going in one direction, and find out through our research that we should have gone in a different direction. When you think you finally have a thesis statement that is good to go for your speech, take a second and make sure it adheres to the criteria shown below.

Thesis checklist questions.

Preview of Speech

The preview, as stated in the introduction portion of our readings, reminds us that we will need to let the audience know what the main points in our speech will be. You will want to follow the thesis with the preview of your speech. Your preview will allow the audience to follow your main points in a sequential manner. Spoiler alert: The preview when stated out loud will remind you of main point 1, main point 2, and main point 3 (etc. if you have more or less main points). It is a built in memory card!

Key Takeaways

Introductions are foundational to an effective public speech.

  • A thesis statement is instrumental to a speech that is well-developed and supported.
  • Be sure that you are spending enough time brainstorming strong attention getters and considering your audience’s goal(s) for the introduction.
  • A strong thesis will allow you to follow a roadmap throughout the rest of your speech: it is worth spending the extra time to ensure you have a strong thesis statement.

What you’ll learn to do: evaluate argumentative essays and thesis statements

Decorative image.

An academic argument asserts a claim and supports that claim with evidence.

The goal of an argument is to convince readers that the writer’s position is reasonable, valid, and worthy of consideration. Therefore, an argumentative thesis statement needs to be not only clear and focused, but also debatable, assertive, and reasoned. Additionally, an argumentative thesis must be able to be supported with evidence.

In this section, you’ll learn about argumentative essays and how they are shaped around strong, clear thesis statements.

Arguments and Information

Learning Objectives

  • Define what an argument is
  • Introduce ethos, pathos, and logos
  • Identify the argument structure of claim, evidence, and warrant
  • Explore effective language

You may be wondering, “What exactly is an argument? Haven’t I already decided on my main argument and topic?”

An argument is a series of statements in support of a claim, assertion, or proposition. So far, we’ve discussed thesis statements as the main argumentative through-line for a speech—it’s what you want to inform, persuade, or entertain the audience about.

Your thesis statement, however, is just one component of an argument, i.e. “here’s what I want to inform you about / persuade you to consider.” It is the main claim of your speech. Your task is to prove the reliability of that claim (with evidence) and demonstrate, through the body of the speech, how or why that information should matter to the audience. In this chapter, we will fill in the other structural components of an argument to make sure that your thesis statement has adequate support and proof. We’ll also outline the importance of language and tips to guarantee that your language increases the effective presentation of your argument.

An Overview of Arguments

It may be tempting to view arguments as only relevant to persuasion or persuasive speeches. After all, we commonly think of arguments as occurring between different perspectives or viewpoints with the goal of changing someone’s mind. Arguments are important when persuading (and we will re-visit persuasive arguments in Chapter 13), but you should have clear evidence and explanations for any type of information sharing.

All speech types require proof to demonstrate the reliability of their claims. Remember, when you speak, you are being an advocate and selecting information that you find relevant to your audience, so arguments are necessary to, at a bare minimum, build in details about the topic’s importance.

With speeches that primarily inform, a sound argument demonstrates the relevance and significance of the topic for your audience. In other words, “this is important information because…” or “here’s why you should care about this.” If you are giving a ceremonial speech, you should provide examples of your insights. In a speech of introduction, for example, you may claim that the speaker has expertise, but you should also provide evidence of their previous accomplishments and demonstrate why those accomplishments are significant.

For each speech type, a well-crafted speech will have multiple arguments throughout. Yes, your thesis statement is central to speech, and your content should be crafted around that idea – you will use your entire speech to prove the reliability of that statement. You will also have internal arguments, i.e. your speech’s main points or the “meat” of your speech.

All speech types require arguments, and all arguments use the rhetorical appeals of ethos, pathos, and logos to elicit a particular feeling or response from your audience.

Ethos , or establishing your credibility as a speaker, is necessary for any speech. If you’re informing the audience about a key topic, they need to know that you’re a trustworthy and reliable speaker. A key way to prove that credibility is through crafting arguments that are equally credible. Using reliable and well-tested evidence is one way to establish ethos.

Using reason or logic, otherwise known as logos , is also a key rhetorical appeal. By using logos, you can select logical evidence that is well-reasoned, particularly when you’re informing or persuading. We’ll talk more about logic and fallacies (to avoid) in Chapter 13.

Pathos , or emotional appeals, allows you to embed evidence or explanations that pull on your audience’s heartstrings or other feelings and values. Pathos is common in ceremonial speeches, particularly speeches that eulogize or celebrate a special occasion.

All three rhetorical appeals are important mechanisms to motivate your audience to listen or act. All three should be done ethically (see Chapter 1) and with the speech context and audience in mind.

Regardless of which rhetorical proof you use, your arguments should be well-researched and well-structured. Below, we explore the structure of an argument in more detail.

The Structur e : Claim, Evidence, Warrant

Arguments have the following basic structure (see Figure 5.1):

  • Claim: the main proposition crafted as a declarative statement.
  • Evidence: the support or proof for the claim.
  • Warrant: the connection between the evidence and the claim.

Each component of the structure is necessary to formulate a compelling argument.

The Toulmin Model

British Philosopher, Stephen Toulmin, created the “Toulmin Model” – a model that describes the structure of an argument or method of reasoning. Claim, evidence, and warrant are, if done well, necessary to create a good argument (O’Connor, 1958).

Visual layout of claim, evidence, and warrant

Evidence and warrants are the specifics that make your ideas, arguments, assertions, points, or concepts real and concrete by relating the information to your audience. Not all audiences are compelled by the same evidence, for example, so creating a well-structured argument also means being responsive to audiences.

Consider going to lunch with a friend. Your friend suggests a restaurant that you have not heard of, so you request some additional information, proof, or evidence of their choice. We could map the argument like this:

  • Claim: “Let’s go to Jack’s Shack for lunch.”
  • Evidence: “I have been there a few times and they have good servers.”

So far, your friend is highlighting service as the evidence to support their claim that Jack’s Shack is a good choice for lunch. However, the warrant is still missing. For a warrant, they need to demonstrate why good service is sufficient proof to support their claim. Remember that the warrant is the connection. For example:

  • Warrant: “You were a server, so I know that you really appreciate good service. I have never had a bad experience at Jack’s Shack, so I am confident that it’s a good lunch choice for both of us.”

In this case, they do a good job of both connecting the evidence to the claim and connecting the argument to their audience – you! They have selected evidence based on your previous experience as a server (likely in hopes to win you over to their claim!).

Using “claim, evidence, and warrant” can assist you in verifying that all parts of the argumentative structure are present. Below, we dive deeper into each category.

A claim is a declarative statement or assertion—it is something that you want your audience to accept or know. Like we’ve mentioned, your thesis statement is a key claim in your speech because it’s the main argument that you’re asking the audience to consider.

Different claims serve different purposes. Depending on the purpose of the argument, claims can be factual, opinionated, or informative. Some claims, for example, may be overtly persuading the audience to change their mind about a controversial issue, i.e. “you should support this local policy initiative.”

Alternatively, a claim may develop the significance of a topic (i.e. “this is why you should care about this information”) or highlight a key informative component about a person, place, or thing (“Hillary Clinton had an intriguing upbringing”). You might, for example, write a speech that informs the audience about college textbook affordability. Your working thesis might read, “Universities are developing textbook affordability initiatives.” Your next step would be to develop main points and locate evidence that supports your claim.

It’s important to develop confidence around writing and identifying your claims. Identifying your main ideas will allow you to then identify evidence in support of those declarative statements. If you aren’t confident about what claims you’re making, it will be difficult to identify the evidence in support of that idea, and your argument won’t be structurally complete. Remember that your thesis statement your main claim, but you likely have claims throughout your speech (like your main points).

Evidence is the proof or support for your claim. It answers the question, “how do I know this is true?” With any type of evidence, there are three overarching considerations.

First, is this the most timely and relevant type of support for my claim? If your evidence isn’t timely (or has been disproven), it may drastically influence the credibility of your claim.

Second, is this evidence relatable and clear for my audience? Your audience should be able to understand the evidence, including any references or ideas within your information. Have you ever heard a joke or insight about a television show that you’ve never seen? If so, understanding the joke can be difficult. The same is true for your audience, so stay focused on their knowledge base and level of understanding.

Third, did I cherry-pick? Avoid cherry-picking evidence to support your claims. While we’ve discussed claims first, it’s important to arrive at a claim after seeing all the evidence (i.e. doing the research). Rather than finding evidence to fit your idea (cherry-picking), the evidence should help you arrive at the appropriate claim. Cherry-picking evidence can reduce your ethos and weakened your argument.

With these insights in mind, we will introduce you to five evidence types : examples, narratives, facts, statistics, and testimony. Each provides a different type of support, and it’s suggested that you integrate a variety of different evidence types. Understanding the different types of evidence will assist as you work to structure arguments and select support that best fits the goal of your speech.

Examples are specific instances that illuminate a concept. They are designed to give audiences a reference point. An example must be quickly understandable—something the audience can pull out of their memory or experience quickly.

Evidence by example would look like this:

Claim: Textbook affordability initiatives are assisting universities in implementing reputable, affordable textbooks.

Evidence : Ohio has implemented a textbook affordability initiative, the Open Ed Collaborative, to alleviate the financial strain for students (Jaggers, Rivera, Akani, 2019).

Ohio’s affordability initiative functions as evidence by example. This example assists in demonstrating that such initiatives have been successfully implemented. Without providing an example, your audience may be skeptical about the feasibility of your claim.

Examples can be drawn directly from experience, i.e. this is a real example, or an example can be hypothetical where audiences are asked to consider potential scenarios.

Narratives are stories that clarify, dramatize, and emphasize ideas. They have, if done well, strong emotional power (or pathos). While there is no universal type of narrative, a good story often draws the audience in by identifying characters and resolving a plot issue. Narratives can be personal or historical.

Person narratives are powerful tools to relate to your audience and embed a story about your experience with the topic. As evidence, they allow you to say, “I experienced or saw this thing first hand.” As the speaker, using your own experience as evidence can draw the audience in and help them understand why you’re invested in the topic. Of course, personal narratives must be true. Telling an untrue personal narrative may negatively influence your ethos for an audience.

Historical narratives (sometimes called documented narratives) are stories about a past person, place, or thing. They have power because they can prove and clarify an idea by using a common form— the story. By “historical” we do not mean that the story refers to something that happened many years ago, only that it has happened in the past and there were witnesses to validate the happening. Historical narratives are common in informative speeches.

Facts are observations, verified by multiple credible sources, that are true or false. The National Center for Science Education (2008) defines fact as:

an observation that has been repeatedly confirmed an . . . is accepted as ‘true.’ Truth in science, however, is never final and what is accepted as a fact today may be modified or even discarded tomorrow.

“The sun is a star” is an example of a fact. It’s been observed and verified based on current scientific understanding and categorization; however, future technology may update or disprove that fact.

In our modern information age, we recommend “fact-checking a fact” because misinformation can be presented as truth. This means verifying all facts through credible research (check back to Chapter 4 on research). Avoid taking factual information for granted and make sure that the evidence comes from reputable sources that are up-to-date.

S tatistics are the collection, analysis, comparison, and interpretation of numerical data. As evidence, they are useful in summarizing complex information, quantifying, or making comparisons. Statistics are powerful pieces of evidence because numbers appear straightforward. Numbers provide evidence that quantifies, and statistics can be helpful to clarify a concept or highlighting the depth of a problem.

You may be wondering, “What does this actually mean ?” (excuse our statistical humor). We often know a statistic when we find one, but it can be tricky to understand how a statistic was derived.

Averages and percentages are two common deployments of statistical evidence.

An “ a verage ” can be statistically misleading, but it often refers to the mean of a data set. You can determine the mean (or average) by adding up the figures and dividing by the number of figures present. If you’re giving a speech on climate change, you might note that, in 2015, the average summer temperature was 97 degrees while, in 1985, it was just 92 degrees.

When using statistics, comparisons can help translate the statistic for an audience. In the example above, 97 degrees may seem hot, but the audience has nothing to compare that statistic to. The 30-year comparison assists in demonstrating a change in temperature.

A percentag e expresses a proportion of out 100. For example, you might argue that “textbook costs have risen more than 1000% since 1977” (Popken, 2015). By using a statistical percentage, 1000% sounds pretty substantial. It may be important, however, to accompany your percentage with a comparison to assist the audience in understanding that “This is 3 times higher than the normal rate of inflation” (UTA Libraries). You might also clarify that “college textbooks have risen more than any other college-related cost” (Bureau of Labor Statistics, 2016).

You are responsible for the statistical information that you deploy. It’s all too common for us as information consumers to grab a quick statistic that sounds appealing, but that information may not be reliable.

Be aware of three major statistical issues: small samples, unrepresentative samples, and correlation as causation. In a small sample, an argument is being made from too few examples. In unrepresentative sample, a conclusion is based on surveys of people who do not represent, or resemble, the ones to whom the conclusion is being applied. Finally, it’s common to conflate correlation as causation. In statistics, a correlation refers to the relationship between two variables while causation means that one variable resulted from the other. Be careful not to assume that a correlation means that something has caused the second.

A few other statistical tips:

  • Use statistics as support, not as a main point. The audience may cringe or tune you out for saying, “Now I’d like to give you some statistics about the problem of gangs in our part of the state.” That sounds as exciting as reading the telephone book! Use the statistics to support an argument.
  • In regard to sources, depend on the reliable ones. Use Chapter 4 as a guide to criticizing and evaluating credible sources.
  • Do not overuse statistics. While there is no hard and fast rule on how many to use, there are other good supporting materials and you would not want to depend on statistics alone. You want to choose the statistics and numerical data that will strengthen your argument the most and drive your point home. Statistics can have emotional power as well as probative value if used sparingly.
  • Explain your statistics as needed, but do not make your speech a statistics lesson. If you say, “My blog has 500 subscribers” to a group of people who know little about blogs, that might sound impressive, but is it? You can also provide a story of an individual, and then tie the individual into the statistic. After telling a story of the daily struggles of a young mother with multiple sclerosis, you could follow up with “This is just one story in the 400,000 people who suffer from MS in the United States today, according to National MS Society.”

Testimony is the words of others. As evidence, testimony can be valuable to gain insight into an expert or a peer’s opinion, experience, or expertise about a topic. Testimony can provide an audience with a relevant perspective that the speaker isn’t able to provide. We’ll discuss two types of testimony: expert and non-expert.

Expert Testimony

What is an expert? An expert is someone with recognized credentials, knowledge, education, and/or experience in a subject. To quote an expert on expertise, “To be an expert, someone needs to have considerable knowledge on a topic or considerable skill in accomplishing something” (Weinstein, 1993).

A campus bookstore manager could provide necessary testimony on the changing affordability of textbooks over time, for example. As someone working with instructors, students, and publishers, the manager would likely have an insight and a perspective that would be difficult to capture otherwise. They would provide unique and credible evidence.

In using expert testimony, you should follow these guidelines:

  • Use the expert’s testimony in their relevant field. A person may have a Nobel Prize in economics, but that does not make them an expert in biology.
  • Provide at least some of the expert’s relevant credentials.
  • If you interviewed the expert yourself, make that clear in the speech also. “When I spoke with Dr. Mary Thompson, principal of Park Lake High School, on October 12, she informed me that . . .”

Expert testimony is one of your strongest supporting materials to prove your arguments. When integrating their testimony as evidence, make sure their testimony clearly supports your claim (rather than an interesting idea on the topic that is tangential to your assertions).

Non-Expert/Peer Testimony

Any quotation from a friend, family member, or classmate about an incident or topic would be peer testimony. It is useful in helping the audience understand a topic from a personal point of view. For example, you may draw on testimony from a campus student who was unable to afford their campus textbooks. While they may lack formalized expertise in textbook affordability, their testimony might demonstrate how the high cost limited their engagement with the class. Their perspective and insight would be valuable for an audience to hear.

The third component of any argument is the warrant. Warrants connect the evidence and the claim. They often answer the question, “what does this mean?” Warrants are an important component of a complete argument because they:

  • Highlight the significance of the evidence;
  • Detail how the evidence supports the claims;
  • Outline the relevance of the claim and evidence to the audience.

For example, consider the claim that “communication studies provide necessary skills to land you a job.” To support that claim, you might locate a statistic and argue that, “The New York Times had a recent article stating that 80% of jobs want good critical thinking and interpersonal skills.” It’s unclear, however, how a communication studies major would prepare someone to fulfill those needs. To complete the argument, you could include a warrant that explains, “communication studies classes facilitate interpersonal skills and work to embed critical thinking activities throughout the curriculum.” You are connecting the job skills (critical thinking) from the evidence to the discipline (communication studies) from your claim.

Despite their importance, warrants are often excluded from arguments. As speechwriters and researchers, we spend lots of time with our information and evidence, and we take for granted what we know. If you are familiar with communication studies, the connection between the New York Times statistic referenced above and the assertion that communication studies provides necessary job skills may seem obvious. For an unfamiliar audience, the warrant provides more explanation and legitimacy to the evidence.

We know what you’re thinking: “Really? Do I always need an explicit warrant?”

It’s true that some warrants are inferred , meaning that we often recognize the underlying warrant without it being explicitly stated. For example, I might say, “The baking time for my cookies was too hot. The cookies burned.” In this statement, I’m claiming that the temperature is too hot and using burnt cookies as the evidence. We could reasonably infer the warrant, i.e. “burnt cookies are a sign that they were in the oven for too long.”

Inferred warrants are common in everyday arguments and conversations; however, in a formal speech, having a clear warrant will increase the clarity of your argument. If you decide that no explicit warrant is needed, it’s still necessary to ask, “what does this argument mean for my thesis? What does it mean for my audience?” Your goal is to keep as many audience members listening as possible, and warrants allow you to think critically about the information that you’re presenting to that audience.

When writing warrants, keep the following insights in mind:

  • Avoid exaggerating your evidence, and make sure your warrant honors what the evidence is capable of supporting;
  • Center your thesis statement. Remember that your thesis statement, as your main argument, should be the primary focus when you’re explaining and warranting your evidence.
  • A good warrant should be crafted with your content and context in mind. As you work on warrants, ask, “why is this claim/evidence important here? For this argument? Now? For this audience?”
  • Say it with us: ethos, pathos, and logos! Warrants can help clarify the goal of your argument. What appeal are you using? Can the warrant amplify that appeal?

Now that you have a better understanding of each component of an argument, let’s conclude this section with a few complete examples.

Claim : The Iowa Wildcats will win the championship. Evidence: In 2019, the National Sporting Association found that the Wildcats had the most consistent and well-rounded coaching staff. Referees of the game agreed, and also praised the players ability for high scoring. Warrant: Good coaching and high scoring are probable indicators of past champions and, given this year’s findings, the Wildcat’s are on mark to win it all.

Here’s an example with a more general approach to track the potential avenues for evidence:

Claim: Sally Smith will win the presidential election. Evidence: [select evidence that highlights their probable win, including: they’ve won the most primaries; they won the Iowa caucus; they’re doing well in swing states; they have raised all the money; they have the most organized campaign.” Warrant: [based on your evidence select, you can warrant why that evidence supports a presidential win].

Using Language Effectively

Claim, evidence, and warrant are useful categories when constructing or identifying a well-reasoned argument. However, a speech is much more than this simple structure over and over (how boring, huh?).

When we craft arguments, it’s tempting to view our audience as logic-seekers who rely solely on rationality, but that’s not true. Instead, Walter Fisher (1984) argues that humans are storytellers, and we make sense of the world through good stories. A good speech integrates argumentative components while telling a compelling story about your argument to the audience. A key piece of that story is how you craft the language—language aids in telling an effective story.

We’ll talk more about language in Chapter 7 (verbal delivery), but there are a few key categories to keep in mind as you construct your argument and story.

Language: What Do We Mean?

Language is any formal system of gestures, signs, sounds, and symbols used or conceived as a means of communicating thought, either through written, enacted, or spoken means. Linguists believe there are far more than 6,900 languages and distinct dialects spoken in the world today (Anderson, 2012). Despite being a formal system, language results in different interpretations and meanings for different audiences.

It is helpful for public speakers to keep this mind, especially regarding denotative and connotative meaning. Wrench, Goding, Johnson, and Attias (2011) use this example to explain the difference:

When we hear or use the word “blue,” we may be referring to a portion of the visual spectrum dominated by energy with a wave-length of roughly 440–490 nanometers. You could also say that the color in question is an equal mixture of both red and green light. While both of these are technically correct ways to interpret the word “blue,” we’re pretty sure that neither of these definitions is how you thought about the word. When hearing the word “blue,” you may have thought of your favorite color, the color of the sky on a spring day, or the color of a really ugly car you saw in the parking lot. When people think about language, there are two different types of meanings that people must be aware of: denotative and connotative. (p. 407)

Denotative meaning is the specific meaning associated with a word. We sometimes refer to denotative meanings as dictionary definitions. The scientific definitions provided above for the word “blue” are examples of definitions that might be found in a dictionary. Connotative meaning is the idea suggested by or associated with a word at a cultural or personal level. In addition to the examples above, the word “blue” can evoke many other ideas:

  • State of depression (feeling blue)
  • Indication of winning (a blue ribbon)
  • Side during the Civil War (blues vs. grays)
  • Sudden event (out of the blue)
  • States that lean toward the Democratic Party in their voting
  • A slang expression for obscenity (blue comedy)

Given these differences, the language you select may have different interpretations and lead to different perspectives. As a speechwriter (and communicator), being aware of different interpretations can allow you select language that is the most effective for your speaking context and audience.

Using Language to Craft Your Argument

Have you ever called someone a “wordsmith?” If so, you’re likely complimenting their masterful application of language. Language is not just something we use; it is part of who we are and how we think. As such, language can assist in clarifying your content and creating an effective message.

Achieve Clarity

Clear language is powerful language. If you are not clear, specific, precise, detailed, and sensory with your language, you won’t have to worry about being emotional or persuasive, because you won’t be understood. The goal of clarity is to reduce abstraction; clarity will allow your audience to more effectively track your argument and insight, especially because they only have one chance to listen.

Concreteness aids clarity. We usually think of concreteness as the opposite of abstraction. Language that evokes many different visual images in the minds of your audience is abstract language. Unfortunately, when abstract language is used, the images evoked might not be the ones you really want to evoke. Instead, work to be concrete, detailed, and specific. “Pity,” for example, is a bit abstract. How might you describe pity by using more concrete words?

Clear descriptions or definitions can aid in concreteness and clarity.

To define means to set limits on something; defining a word is setting limits on what it means, how the audience should think about the word, and/or how you will use it. We know there are denotative and connotative definitions or meanings for words, which we usually think of as objective and subjective responses to words. You only need to define words that would be unfamiliar to the audience or words that you want to use in a specialized way.

Describing is also helpful in clarifying abstraction. The key to description is to think in terms of the five senses: sight (visual:  how does the thing look in terms of color, size, shape); hearing (auditory: volume, musical qualities); taste (gustatory: sweet, bitter, salty, sour, gritty, smooth, chewy); smell (olfactory: sweet, rancid, fragrant, aromatic, musky); and feel (tactile: rough, silky, nubby, scratchy).

If you were, for example, talking about your dog, concrete and detailed language could assist in “bring your dog to life,” so to speak, in the moment.

Sharpei-mix dog in grass

  • Boring and abstract: My dog is pretty great. He is well behaved, cute, and is friendly to all of our neighbors. I get a lot of compliments about him, and I really enjoy hanging out with him outside in the summer.
  • Concrete and descriptive: Buckley, my golden-brown Sharpei mix, is a one-of-a-kind hound. Through positive treat reinforcement, he learned to sit, shake, and lay down within one month. He will also give kisses with his large and wrinkly snout. He greats passing neighbors with a smile and enjoys Midwest sunbathing on our back deck in the 70-degree heat.

 Doesn’t the second description do Image 5.2 more justice ? Being concrete and descriptive paints a picture for the audience and can increase your warrant’s efficacy. Being descriptive, however, doesn’t mean adding more words. In fact, you should aim to “reduce language clutter.” Your descriptions should still be purposeful and important.

Be Effective

Language achieves effectiveness by communicating the right message to the audience. Clarity contributes to effectiveness, but effectiveness also includes using familiar and interesting language.

Familiar language is language that your audience is accustomed to hearing and experiencing. Different communities and audience use language differently. If you are part of an organization, team, or volunteer group, there may be language that is specific and commonly used in those circles. We call that language jargon, or specific, technical language that is used in a given community. If you were speaking to that community, drawing on those references would be appropriate because they would be familiar to that audience. For other audiences, drawing on jargon would be ineffective and either fail to communicate an idea to the audience or implicitly community that you haven’t translated your message well (reducing your ethos).

In addition to using familiar language, draw on language that’s accurate and interesting. This is difficult, we’ll admit it! But in a speech, your words are a key component of keeping the audience motivated to listen, so interesting language can peak and maintain audience interest.

Active language is interesting language. Active voice , when the subject in a sentence performs the action, can assist in having active and engaging word choices. An active sentence would read, “humans caused climate change” as opposed to a passive approach of, “climate change was caused by humans.” Place subjects at the forefront. A helpful resource on active voice can be found here.

You must, however, be reflexive in the language process.

Practicing Reflexivity

Language reflects our beliefs, attitudes, and values – words are the mechanism we use to communicate our ideas or insights. As we learned in Chapter 1, communication both creates and is created by culture. When we select language, we are also representing and creating ideas and cultures – language has a lot of power.

To that end, language should be a means of inclusion and identification, rather than exclusion.

You might be thinking, “Well I am always inclusive in my language,” or “I’d never intentionally use language that’s not inclusive.” We understand, but intention is less important than effect.

Consider the term “millennial”— a categorization that refers to a particular age group. It can be useful to categorize different generations, particularly from a historical and contemporary perspective. However, people often argue that “millennials are the laziest generation” or “millennials don’t know hard work!” In these examples, the intention may be descriptive, but they are selecting language that perpetuates unfair and biased assumptions about millions of people. The language is disempowering (and the evidence, when present, is weak).

Language assists us in categorizing or understanding different cultures, ideas, or people; we rely on language to sort information and differentiate ourselves. In turn, language influences our perceptions, even in unconscious and biased ways.

The key is to practice reflexivity about language choices. Language isn’t perfect, so thinking reflexively about language will take time and practice.

For example, if you were crafting a hypothetical example about an experience in health care, you might open with a hypothetical example: “Imagine sitting for hours in the waiting room with no relief. Fidgeting and in pain, you feel hopeless and forgotten within the system. Finally, you’re greeted by the doctor and he escorts you to a procedure room.” It’s a great story and there is vivid and clear language. But are there any changes that you’d make to the language used?

Remember that this is a hypothetical example. Using reflexive thinking, we might question the use of “he” to describe the doctor. Are there doctors that are a “he”? Certainly. Are all doctors a “he”? Certainly not. It’s important to question how “he” gets generalized to stand-in for doctors or how we may assume that all credible doctors are men.

Practicing reflexivity means questioning the assumptions present in our language choices (like police men rather than police officers). Continue to be conscious of what language you draw on to describe certain people, places, or ideas. If you aren’t sure what language choices are best to describe a group, ask; listen; and don’t assume.

In this chapter, we discussed crafting complete, well-reasoned arguments. Claim, evidence, and warrant are helpful structural components when crafting arguments. Use Chapter 4 to aid in research that will enable you to locate the best evidence for each claim within your speech.

Remember, too, that language plays a central role in telling a compelling story. Up next: organizing and outlining.
