Persuasive Strategies

Do you think you are easily persuaded? If you are like most people, you aren’t swayed easily to change your mind about something. Persuasion is difficult because changing views often makes people feel like they were either not informed or ill-informed, which also means they have to admit they were wrong about something. We will learn about nine persuasive strategies that you can use to more effectively influence audience members’ beliefs, attitudes, and values. They are ethos, logos, pathos, positive motivation, negative motivation, cognitive dissonance, appeal to safety needs, appeal to social needs, and appeal to self-esteem needs.  In this excerpt, we will learn about ethos.

Ethos, Logos, and Pathos

Ethos, logos, and pathos were Aristotle’s three forms of rhetorical proof, meaning they were primary to his theories of persuasion. Ethos refers to the credibility of a speaker and includes three dimensions: competence, trustworthiness, and dynamism. The two most researched dimensions of credibility are competence and trustworthiness (Stiff & Mongeau, 2003).

Competence refers to the perception of a speaker’s expertise in relation to the topic being discussed. A speaker can enhance their perceived competence by presenting a speech based in solid research and that is well organized and practiced. Competent speakers must know the content of their speech and be able to effectively deliver that content. Trustworthiness refers to the degree that audience members perceive a speaker to be presenting accurate, credible information in a nonmanipulative way. Perceptions of trustworthiness come from the content of the speech and the personality of the speaker. In terms of content, trustworthy speakers consider the audience throughout the speech-making process, present information in a balanced way, do not coerce the audience, cite credible sources, and follow the general principles of communication ethics. In terms of personality, trustworthy speakers are also friendly and warm (Stiff & Mongeau, 2003).

Dynamism refers to the degree to which audience members perceive a speaker to be outgoing and animated (Stiff & Mongeau, 2003). Two components of dynamism are charisma and energy. Charisma refers to a mixture of abstract and concrete qualities that make a speaker attractive to an audience. Charismatic people usually know they are charismatic because they’ve been told that in their lives, and people have been attracted to them. The dynamism of the speaker can also be seen through their demonstration of goodwill toward the audience, or whether they have the audience's best interests at heart.

Unfortunately, charisma is difficult to intentionally develop, and some people seem to have a naturally charismatic personality, while others do not. Even though everyone can’t embody the charismatic aspect of dynamism, the other component of dynamism, energy, is something that everyone can tap into. Communicating enthusiasm for your topic and audience by presenting relevant content and using engaging delivery strategies such as vocal variety and eye contact can increase your dynamism.

Speakers should strive to appeal to ethos, logos, and pathos within a speech. A speech built primarily on ethos might lead an audience to think that a speaker is full of himself or herself. 

Review of Ethos

   • using appropriate language and grammar;
   • being perceived as likable; and
