People report that the planchette quivers and slides across the board. As people laugh nervously and give one another suspicious looks everyone seems to have one thought in mind: Why does it feel as if it is moving? The answer is simple.
The heightened fear can make hands tremble even more causing the trivet to skitter across the board again. Feeling frightened as a group heightens the intensity of the experience. If you are in a group, especially if you are close, you start empathizing, and you start experiencing the same thing. For over years, Ouija boards have amazed, entertained, and even frightened people with mysterious messages from the beyond. Chris French, a professor emeritus of psychology at Goldsmiths University of London, has spent decades studying the science behind supernatural experiences, but his first brush with Ouija boards came when he was an undergrad.
He and his friends made their own Ouija board by writing the alphabet on a piece of paper and using an upturned wineglass as a planchette.
However, he adds, he and his friends were simply experiencing a long-known phenomenon called the ideomotor effect. Basically, the ideomotor effect is subconscious, involuntary movement; scientists first documented it in What about the messages?
Our subconscious minds are responsible for those too. The participants were equipped with eye tracking devices so that the researchers could study their — largely unconscious — predictive eye movements.
That is, the researchers wanted to see if the participants first glanced at the letters they would later move the planchette to.
In the Ouija condition, the participants were asked to use the board as they normally would. As expected, the data analysis revealed that participants made more predictive eye movements in the voluntary condition than they did in the regular one. Unsurprisingly, given the underlying mechanisms of the sense of agency, the participants reported feeling much less in control in the Ouija condition than they did in the voluntary one.
However, when the researchers looked to see whether at least one participant in each pair made a predictive eye movement, they found some interesting results.
So, when the Ouija board was used as usual, at least one participant knew where the planchette was going. Participants who said that they thought the board can facilitate communication with spirits were more likely to report that the planchette had moved on its own.
