Abstract

"Few of the PK reports fulfill the basic requirement of a psychological experiment. To have psychological justification, there must be a controlled comparison such as wish for versus wish against, or wish for versus no wishing, or Believers versus Disbelievers . . . . Evidence of PK as a psychological phenomenon is therefore totally lacking. And this deficiency will persist until the effect is produced in the presence of a specified psychological variable, and the effect does not appear in its absence."
