Personal values and expert testimony

This paper explores challenges to personal values which are inherent in the situation that any expert witness with a scientific background finds himself or herself in when working in the legal context. Case histories are relied on to make the point that time is needed for psychologists and lawyers to develop an effective and ethically sound working relationship. The paper takes issue with the notion that the experts should be constrained in their behavior and their testimony by new rules and guidelines for testimony content. It further argues that the model of going public with psychological knowledge is a time-honored function of members of the American Psychological Association.The author was supported in the preparation of this article by grant No. DAR 7926805 from the National Science Foundation.
