Hans J. Eysenck and Carl Sargent

Experiments using computers that display random numbers (called a random—number generator, or RNG) and illuminate lights in a random pattern (known as a random—event generator, or REG) show that psi exist, according to Hans J. Eysenck and Carl Sargent in the following selection. Test subjects recorded their guesses as to which number or light would be displayed next and the number of their correct answers were above what chance would predict. They assert that when the test subjects were asked to score below chance-to deliberately guess wrong-their answers were below what chance would predict. In experiments testing psychokinesis in which test subjects tried to get the lights to light up in a certain pattern, the authors report that their success rate was well above chance. When asked...
