Perception that involves awareness of information about something (such as a person or event) not gained through the sense s and not deducible from previous experience.
Classic forms of ESP include telepathy, clairvoyance, and precognition. No conclusive demonstrations of the existence of ESP in any individual have been given, but popular belief in the phenomenon remains widespread, and people who claim to possess ESP are sometimes employed by investigative teams searching for missing persons or things.
