Abstract

A single subject attempted to record in advance the random order in which ESP symbols would be written in prescribed columns of record sheets. The calls were made in New York City and mailed to Durham, where the targets were taken from a random number table. Special precautions were used to exclude any kind of subjective influence in the selection of the targets. A total of 5998 trials gave a negative deviation from main chance expectation which was statistically significant (P = .0007). The interval between responses and the target selections did not affect the results.
