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.
Principles 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.
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
- Choose a topic that is current.
- Not current. People should use seat belts.
- Current. People should not text while driving.
- Choose a topic that is controversial.
- Not controversial. People should recycle.
- Controversial. Recycling should be mandatory by law.
- Choose a topic that meaningfully impacts society.
- Not as impactful. Superman is the best superhero.
- Impactful. Colleges and universities should adopt zero-tolerance bullying policies.
- Write a thesis statement that is clearly argumentative and states your stance.
- 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.
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.
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).

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 the chapter titled “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.
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 the chapter titled “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 the chapter titled “Preparing a Speech”, but we will review them here with an example:
- Step 1: Attention
- 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.
- Step 2: Need
- 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.
- Step 3: Satisfaction
- 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.
- Step 4: Visualization
- 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.
- Step 5: Action
- 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.
Example of Monroe's Motivated Sequence in Advertising:
- 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.
- Speakers should adapt their persuasive approach based on audience members’ orientation toward the proposal.
- 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.
- Persuasive speeches include the following propositions: fact, value, and policy.
- 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.
