The effectiveness of psychological profiles

Although psychological profiling of unknown offenders is becoming a popular media topic, there has been little research on the effectiveness of these profiles. In this study, surveys were sent to 95 police departments in the United States, asking participants to indicate if they use psychological profiles to solve crimes. The survey also asked whether the profile was helpful, and in what sense it was helpful. The results from this sample indicate that profiles are used mainly in cases of rape and homicide, and that police officers view profiles as an effective tool to guide interrogations of a suspect and to guide the criminal investigation but not necessarily to identify the suspect.
