Self-disclosure can help during a public presentation by persuading the audience with the implementation of ethos as a mode of persuasion. When the speaker opens up about his views, feelings, and ideas to the audience, he is sharing pieces of him which they can relate to. In Greek language, ethos means ethics or character. In this type of persuasion, the audience are convinced by the speaker's credibility of character which proves his worth as a credible source of information.
