Why is important to be a credible speaker? The audience’s perception of your

effectiveness as a communicator is called source credibility, ethos

Four concepts of source credibility:

• Common ground: pointing out what features you share with your audience.

(example: all of us, we students…)

• Trustworthiness: the degree to which the audience perceives the speaker as honest and honorable

(example: people will never fully trust someone who once lied in his speech)

Four concepts of source credibility:

• Competence: a thorough familiarity with topic (an agricultural major’s competence in organic

gardening)

• Dynamism: the energy you expend in delivering your message (speaker who lacks facial expressions vs. speaker who is expressive)
