The experimental psychologist in court

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.The conference on ethics of expert testimony by experimental psychologists was supported by National Science Foundation grant No. ISP-8209940. We thank Rachelle Hollander of the Ethics and Values in Science and Technology Program, Joe Young of the Memory and Cognitive Processes Program, and Eric Juengst of the National Endowment for the Humanities for their help in bringing about the conference.
