Review Questions

• How does the credibility of an expert impact the effectiveness of their testimony in persuasive communication?
  • The credibility of an expert is crucial because it determines how much trust the audience places in their testimony. An expert with recognized qualifications and relevant experience is more likely to influence the audience's beliefs than one without proper credentials. When audiences perceive the expert as knowledgeable and trustworthy, they are more inclined to accept the arguments being made, leading to a stronger persuasive effect.

  • Expert testimony can be effectively integrated with statistical evidence to create a more robust persuasive argument. While expert testimony provides qualitative insights based on specialized knowledge, statistical evidence offers quantitative data that supports the claims being made. This combination enhances the overall credibility of the argument, as it appeals to both logical reasoning and authoritative perspectives, making it more convincing to the audience.
• Evaluate the ethical implications of using expert testimony in persuasive communication, particularly when the expertise may be biased.
