It is not the responsibility of investigators to disprove an extraordinary phenomenon. Proponents must provide evidence. This experiment underscores the need for a scientific process. In removing confounding influences, the double-blind study suggests how these effects occur without proper controls. Proponents must define specifically what they wish to test.
Believers readily attach attributes to phenomena which can claim any effect as evidence.
A proponent may intend to move a specific subject and fail, but then claim that movement of an audience member resulted from his powers. As the wise men become buried under the fool's questions, investigators feel forced to disprove any aspect thrown at them. This experiment isolated one aspect of the individual's claims, specifically his claimed ability to move another person without touching him. A positive result would occur only if the subject moved in the intended direction determined by chance. A greater number of positive results than expected by chance would indicate that the individual could influence a subject.
