Which of the following strategies can enhance speaker credibility?

Demonstrating thorough research significantly enhances speaker credibility because it showcases the speaker's preparation and knowledge of the topic at hand. When a speaker provides evidence-based information, references reputable sources, and illustrates a deep understanding of the subject, the audience is more likely to trust their expertise. This thoroughness not only affirms the speaker's authority but also reassures the audience that they are receiving well-founded insights rather than mere opinions or anecdotal evidence.

Engaging in thorough research can also involve citing statistics, studies, and expert opinions that support the speaker's assertions, further bolstering their credibility. When audiences perceive speakers as informed and well-prepared, they are more inclined to believe and be persuaded by the messages conveyed. This leads to a more impactful and effective presentation overall.
