This Man Wants Magic to Be a Branch of Psychology
In one of these studies, two of Kuhn’s colleagues at Goldsmiths, Krissy Wilson and Christopher C. French, investigated how encountering magic can influence beliefs about the nature of reality. They had an alleged psychic—really, a magician—bend a key in his hand by pretending to use telekinesis. His apparent power over the key was effected, of course, through sleight-of-hand. But for one group of spectating subjects, the psychic attempts something more daring: He places the key on a table and vocally claims that he’s still bending it from afar. Of course, the key did not continue to bend on the table. Still, 33 percent of the subjects who heard the psychic’s suggestion reported that the key did continue to bend, compared to none in the control group who did not hear the suggestion. This percentage of credulous spectators almost doubled when the psychic’s confederate, posing as a spectator, validated the psychic’s suggestion by falsely claiming to see the key bending.
