Most groups who embark on Table Tilting experiments obtain results if they persevere. The table will vibrate or move and raps can be heard on the table or even in the room in which the sitting is taking place. What the origins of these phenomena are is as yet obscure but to my mind there are four possible causes.
1. Fraud. No doubt fraud has played a part in many a Table Tilting sitting but it is difficult to see how it could account for the more extreme instances of movement.
2. Ideomotor Effect. Or the subconscious and involuntary movement of muscles. The more scientific studies of Table Tilting have claimed that this does indeed take place but how can you involuntarily lift a table around a room. I’m suspicious about this explanation.
3. Group Psychokinesis. If it exists it is an explanation that I can certainly live with. The theory is that the group produces this hidden psychic power to produce a force strong enough to move the table. In most experiments the power to move the table increases with the time the sitters have been meeting suggesting that the harmony of the group itself is aiding the build up of power.
4. Spirit Presence. Difficult to discount and equally difficult to prove, although there are some instances where the ‘spirit’ seems to have relayed information unknown to the sitters present.
