The experimental psychologist in court: The ethics of expert testimony.

This special issue comprises articles by psychologists, legal scholars, and ethicists on the ethics of expert testimony by experimental psychologists. In it the major ethical questions facing the prospective expert witness are clarified, and alternative positions on these issues are defined and debated. Fundamentals of moral reasoning are discussed, and the realities of interaction with a judicial system that subjects the psychologist to a variety of pressures and limitations are made apparent. The aim is not to offer final answers to complex ethical questions, but rather to provide a framework within which the questions can be considered by the individual psychologist.
