Glass divination is a technique used by many paranormal research teams at supposedly haunted locations. The aim is to communicate with the spirits of the deceased, who push the glass around a surface (usually a table top) in response to questions. People sit in a circle and focus their ‘energy’ on the glass to help the spirit move it.
Think ‘ouija board without the board’ and you have glass divination.
Successful glass divination is a product of two things; either somebody around the table is intentionally moving the glass, or the people around the table are unconsciously moving the glass. The first is called cheating, the second the ideomotor response.
Scientific tests by American psychologist William James, French chemist Michel Chevreul, English scientist Michael Faraday (Zusne and Jones 1989: 111), and American psychologist Ray Hyman have demonstrated that many phenomena attributed to spiritual or paranormal forces, or to mysterious “energies,” are actually due to ideomotor action.
Furthermore, these tests demonstrate that “honest, intelligent people can unconsciously engage in muscular activity that is consistent with their expectations” (Hyman 1999).
They also show suggestions that guide behavior can be given by subtle cues (Hyman 1977).
The above mentioned ‘suggestions that guide behaviour’ include folklore tales attached to a building, or the stories told to the investigator about what has happened or been witnessed at the location, by the owner of the location owner/staff/residents. If you are aware of the fact that a woman who was murdered is said to haunt a corridor in the building looking for her unmarked grave, it’s likely that that knowledge will influence the way in which the glass moves.
There is a simple yet effective way to test whether the glass is being moved by the people resting one finger upon it. You need to be able to visually see the movement, and I have found that the best way to do this is by covering the glass with putty. Any intentional or unintentional movement of the glass by those touching it will show in the soft putty.
Here’s a demonstration:
Why not try using putty as a control, and letting us know the results?
