Which strategy can effectively enhance speaker credibility?

Presenting counterarguments effectively enhances speaker credibility because it demonstrates the speaker's awareness of different perspectives related to the topic at hand. By acknowledging and addressing opposing viewpoints, a speaker showcases their thorough understanding of the subject, which can evoke trust among the audience. It suggests that the speaker is not only knowledgeable but also fair-minded, as they are willing to engage with and refute alternative ideas rather than simply propagating their own claims. This strategy can lead the audience to perceive the speaker as more credible and trustworthy, thus strengthening their overall message.

Other strategies may contribute to a speaker's effectiveness but do not specifically enhance credibility in the same way. Using humor can engage the audience and create a relaxed atmosphere but might undermine the seriousness of the topic. Presenting lengthy statistics can provide data to back up claims, yet an overload of statistics without context can confuse the audience or diminish engagement. Encouraging audience feedback can foster interaction and make the presentation feel more inclusive, but it doesn't inherently enhance the speaker's credibility; rather, it may simply promote a dialogue.
