Psychiatric expert witnesses in the new millennium.

We may anticipate changes in who is the expert in terms of gender, ethnicity, and professional discipline. We anticipate elaboration of training approaches. We foresee emergence of the "forensic tutor" role. We expect expansion of expert roles outside the courtroom. We expect demands for more constraint of expert roles, increased rigor, and empiric support. We expect vast expansion of technologic approaches to assessment and presentation. We expect evolution of ethical issues with preservation of core forensic values but changes in confidentiality, due process, and the nature of assessments. We expect extreme expansion of hard sciences in relation to understanding psychopathology.
