A forensic psychologist is a professional who applies psychological principles to legal issues. They often work with the criminal justice system, assessing individuals involved in legal cases, such as defendants or victims. Their evaluations can help determine mental competency, risk of reoffending, and the psychological impact of crimes. These psychologists may also provide expert testimony in court, offering insights into a person's mental state at the time of an offense. They often collaborate with law enforcement, attorneys, and other professionals to ensure that psychological factors are considered in legal proceedings, contributing to a fairer justice system.
