Forensic psychology deals with the scientific methods and tests employed in connection with the investigation of a crime. In order to be recognized by a court, the forensic psychologist must be capable of translating the psychological findings into legal language. The forensic psychologist may be trained in organizational, social, clinical, or any other branch of psychology but to be designated as an expert witness in a certain jurisdiction, the relevant training and experience counts. Depending upon experience a psychologist may be considered for more than one jurisdiction. To determine if a person is legally competent to stand trial in case of brain damage or related issues, a forensic neuropsychologist is usually designated by the court. R. J. Gregory, in his work Psychological Testing: History, Principles and Application, has defined the role of forensic psychologist as involving the evaluation of possible malingering, the mental state of insanity plea, competency to stand trial, prediction of violence and risk assessment, child custody in divorce, personal injury, polygraph data and forensic personality assessment.

In 1896, while forensic psychology was not much known, he testified in a murder trial as a forensic psychologist.
In order for a forensic psychologist to be considered credible, an understanding of the adversarial system, in which two advocates represent two opponents before an impartial jury or judge, is a must. Collection of information from someone who is not well versed in the nature of an event, known as hearsay evidence, is another prerequisite. It is also required that the forensic psychologist know about the exclusionary rule that evidence collected in violation of the defendant’s constitutional rights is not permissible for a criminal prosecution. In Shakespeare’s drama The Merchant of Venice, Portia perhaps acted like a forensic psychologist in the case of Shylock the Jew.
