A correspondence ESP experiment with high IQ subjects. Journal of Parapsychology, 31(2), 143–148. (1967).
Abstract:
2 groups of high-IQ volunteers took part in some ESP “distance” tests conducted by correspondence. In a pilot test using the clairvoyance DT technique, the results were below chance to a significant extent (p < .006). In a confirmatory (precognition) test, the results were also negative (p < .05). The impossibility of forming a control group, however, prohibits the conclusion that a correlation was shown between high IQ and the ESP scoring.
