What is the main purpose of expert witnesses in lawsuit claims?

The main purpose of expert witnesses in lawsuit claims is to provide specialized knowledge. In legal proceedings, these witnesses possess expertise in specific fields—such as medicine, engineering, or finance—that is beyond the understanding of the average juror. Their role is to inform the court about complex issues that require an in-depth understanding of technical standards, practices, or scientific principles. By doing so, they help clarify the facts of the case, enabling the judge and jury to make informed decisions based on reliable and credible information.

Expert witnesses contribute valuable insights that can significantly influence the outcome of a case. Their testimony is often based on established norms and evidence, establishing a framework that helps the court to evaluate the claims presented. In contrast, functions such as entertaining juries or swaying public opinion do not align with the legal premise of expert testimony, which is intended to be factual and unbiased. Additionally, the role of confusing the process contradicts the purpose of expert witnesses, which is to facilitate understanding rather than to obfuscate the issues at hand.
