Psi-Tests in Germany

This August, the German skeptics conducted their annual psi-tests. We tested two dowsers and a person claiming to have psychokinetic powers. The first dowser wanted to detect whether an electric cable was plugged in or not. We gave him 50 cables, randomly plugged in or not. The chance expectation obviously is 50/50, that is, 25 hits. His test yielded 26 hits. We required 40 to pass the test.

The second dowser was unable to do any indoor tests due to various “energetic disturbances”. We agreed to test him outdoors if he managed to find an area containing only one “water vein”, while the rest of the area was “clean”. Finding such a place on the surrounding lawn was surprisingly easy for him. We marked the “vein” with sticks. He was then blindfolded and walked around for disorientation (guided by a supervisor). He then had to cross the “water vein” from different vantage points and distances. He was also informed that in some cases he will be asked to walk without crossing the vein. In this case his dowsing rod should not move. The dowser did not have a single correct hit or non-hit in 15 trials.

The third claimant hoped to rotate, just by his psychokinetic powers, a 3 x 3 cm piece of tinfoil balancing on a needle. The needle with the foil was placed under a glass vase to prevent blowing or movements from natural air convection. During the pre-test phase it was obvious that the foil was only moving when he put his hands on the glass, probably causing air convection in the vase. When he kept his hands away from the glass, as he was supposed to in the actual test, nothing moved. And so there was no result in the real test either. -mm-
