Which field might NOT commonly require expert witnesses?

In the context of legal proceedings, expert witnesses are typically individuals with specialized knowledge or expertise in a particular field that can assist the court in understanding evidence or issues that are beyond the understanding of an average person. Fields such as medicine, engineering, and psychology frequently call upon expert witnesses due to the technical and specialized nature of the information relevant to legal cases.

Social activities, on the other hand, generally do not involve intricate technical knowledge or expertise that would necessitate the clarification provided by an expert witness. While certain legal cases may touch on social dynamics, the issues at hand are often more subjective and do not require the scientific or technical validation of an expert. Thus, the role of an expert witness is less relevant in the realm of social activities compared to the other fields mentioned.
