What is the role of "expert witnesses" in trials?

The role of expert witnesses in trials is to provide specialized knowledge relevant to the case. These witnesses possess expertise in specific fields such as medicine, engineering, psychology, or forensics, which can help the jury understand complex evidence or concepts that are outside the realm of common knowledge.

In the judicial process, expert testimony is critical for the court to evaluate certain factual scenarios accurately, as it adds credibility and clarity to the evidence presented. For instance, in a medical malpractice case, a physician might be called as an expert witness to explain the standard of care in that specific medical field and whether it was adhered to by the defendant.

This expertise assists the jury in making informed decisions based on sound principles and data rather than personal biases or assumptions. The emphasis on specialized knowledge underscores the necessity of expert witnesses in ensuring that the trial process adheres to standards of evidence and accuracy, allowing for a fair outcome based on empirical understanding rather than conjecture.
