Chapter 20: Applying Hypnosis in Forensic Contexts

The author identifies five major areas of legal controversy involving hypnosis. First, regulation of hypnosis practitioners raises questions about licensing requirements and professional boundaries, as states increasingly classify hypnosis within psychology or counseling fields, exposing unlicensed practitioners to criminal liability. Second, hypnosis and criminal responsibility examines cases where hypnosis is either used to coerce subjects into illegal acts or invoked as a defense to excuse criminal conduct, though courts have consistently rejected the hypnosis defense as legally and factually implausible. Third, and most extensively litigated, is the admissibility of hypnotically refreshed memories in testimony, where three competing legal frameworks have emerged: open admissibility treating hypnosis as a standard memory aid, per se exclusion banning all hypnotically recovered testimony, and the totality of circumstances approach requiring safeguards against suggestibility. A critical tension exists between legal skepticism and scientific consensus regarding memory contamination, as critics argue hypnosis produces confabulation and false memories while experts contend such distortions reflect general memory properties rather than hypnotic effects. Fourth, legal standards of mental health care have shifted as malpractice liability concerns and evidentiary rules increasingly influence clinical therapeutic practice, creating ethical dilemmas for clinicians using hypnosis with patients. Finally, courtroom advocacy raises unanswered ethical questions about whether attorneys trained in hypnotic communication can legitimately employ subtle persuasion techniques in litigation. Throughout, the chapter identifies a fundamental gap between restrictive evidentiary rules formulated decades ago and contemporary scientific understanding of memory, hypnotic processes, and individual differences in suggestibility. This disconnect illustrates how legal precedent may inadequately reflect evolving empirical knowledge about hypnosis and its effects on cognition and behavior.
