What Does a Forensic Psychologist Do?
A forensic psychologist applies psychological knowledge and assessment methods to questions involving the legal system. Depending on the referral and jurisdiction, forensic psychology can involve psychological evaluations, consultation with attorneys, court-related assessments, risk evaluation, family-law matters, occupational evaluations, and expert testimony.
Forensic psychologists may also help journalists and the public understand psychological concepts raised by high-profile legal cases. When commenting on a case in which the psychologist has not personally evaluated the individuals involved, it is important to distinguish general forensic psychology education from an actual forensic opinion based on a formal evaluation.
