All are related to cold reading and selective thinking . Geraldine Smith, a Toronto psychic, is typical of those claiming to posess psychometric powers. Give her a bracelet and she can tell all kinds of things about the owner just by handling the object. She says she can see auras from the object which tell her about auras of the wearer of the object which tell her about the character, personality, trials and tribulations of the bracelet owner. So she says, but when tested under conditions where the subject was coached in cold reading techniques and advised not to give away any specific information in answering the psychic's questions, Mrs. Smith failed miserably.
Most psychic detectives claim to have psychometric powers.
