A psychic is a person who claims to use extrasensory perception (ESP) to identify information hidden from the normal senses. The word "psychic" is also used as an adjective to describe such abilities. Psychics may be theatrical performers, such as stage magicians, who use techniques such as prestidigitation, cold reading, and hot reading to produce the appearance of such abilities. Psychics appear regularly in fantasy fiction, such as in the novel The Dead Zone by Stephen King.
A large industry and network exists whereby psychics provide advice and counsel to clients. Some famous psychics include Edgar Cayce, Ingo Swann, Peter Hurkos, Jose Ortiz El Samaritano, Miss Cleo, John Edward, and Sylvia Browne. Psychic powers are asserted by psychic detectives and in practices such as psychic archaeology and even psychic surgery.
