Which of the following qualities is important for a good expert witness?

A good expert witness must possess a variety of qualities that contribute to their effectiveness in legal proceedings. High levels of confidence are important, as they help the expert present their findings and opinions persuasively, which can influence the jury or judge's understanding and interpretation of complex issues. Additionally, legal knowledge is vital because it equips the expert with an understanding of legal standards, procedures, and how their expertise applies within the legal framework.

Moreover, the ability to use simple language is crucial for explaining technical concepts in a way that is accessible to non-experts, such as judges and jurors. This clarity aids in ensuring that their testimony is understood and considered effectively. The combination of confidence, legal knowledge, and the ability to communicate simply makes all of these qualities integral to the role of an expert witness, enhancing their overall impact and credibility in court.
