Ouija boards work on a principle known to those studying the mind for more than 160 years: the ideometer effect. In 1852, physician and physiologist William Benjamin Carpenter published a report for the Royal Institution of Great Britain, examining these automatic muscular movements that take place without the conscious will or volition of the individual (think crying in reaction to a sad film, for example). ... Two years ago, Dr. Ron Rensink, professor of psychology and computer science, psychology postdoctoral researcher Hélène Gauchou, and Dr. Sidney Fels, professor of electrical and computer engineering, began looking at exactly what happens when people sit down to use a Ouija board. ... What the team found surprised them: When participants were asked, verbally, to guess the answers to the best of their ability, they were right only around 50 percent of the time, a typical result for guessing. But when they answered using the board, believing that the answers were coming from someplace else, they answered correctly upwards of 65 percent of the time. “It was so dramatic how much better they did on these questions than if they answered to the best of their ability that we were like, ‘This is just weird, how could they be that much better?’” recalled Fels. “It was so dramatic we couldn’t believe it.” The implication was, Fels explained, that one’s non-conscious was a lot smarter than anyone knew. ... They divined another experiment: ... At some point, the participant was blindfolded—and the other player, really a confederate, quietly took their hands off the planchette. This meant that the participant believed he or she wasn’t alone, enabling the kind of automatic pilot state the researchers were looking for, but still ensuring that the answers could only come from the participant. It worked. Rensink says, “Some people were complaining about how the other person was moving the planchette around. That was a good sign that we really got this kind of condition that people were convinced that somebody else was there.” Their results replicated the findings of the experiment with the robot, that people knew more when they didn’t think they were controlling the answers (50 percent accuracy for vocal responses to 65 percent for Ouija responses). They reported their findings in February 2012 issue of Consciousness and Cognition.
