What does "derived credibility" refer to?

Derived credibility refers to the audience's perception of the speaker's credibility as it forms and evolves during the speech. This type of credibility is shaped by the speaker's delivery, the content of their message, their ability to engage with the audience, and their interactions throughout the presentation. As the speech progresses, the audience evaluates the speaker's trustworthiness, competence, and likeability based on the performance observed in real-time. This evaluation can significantly influence how well the audience receives the message and the overall impact of the presentation.

In contrast, prior experience and inherent abilities relate more to the established credibility a speaker brings to the table before they speak, while the overall effectiveness of the speech encompasses more than just the audience's perception of credibility. Therefore, understanding derived credibility is crucial for speakers aiming to enhance their persuasive power during their presentations.
