The use of Hypnotic Techniques in the Evaluation of Criminal Defendants

Abstract

Hypnosis and narcoanalysis have received mixed acceptance in the legal system. Some of the inconsistencies in legal rulings on these, matters are the result of the courts not receiving accurate scientific information. A review of the psychological and psychiatric literature reveals that these techniques can be valid diagnostic tools, particularly in cases of psychogenic amnesia. Thus, expert testimony concerning a defendant's mental state which is based in part on hypnotic interviews should be accepted by the courts. However, these techniques are not “truth serums” and are thus properly excluded from testimony when offered as proof of the truthfulness of a defendant's statements.
