Abstract

It has previously been shown that, in an experiment where ESP occurs, bias against a particular response increases the probability that when the response is made, it will be correct. This is because a decrease in the number of calls of a symbol increases the ratio of total hits (ESP hits plus chance hits) to calls on the symbol. However, correctness of response (indicated by the hit/call ratio) is not the same as psi mediation (indicated by the hit-deviation/target ratio). In all 6 experimental series analyzed by the author, the hit-deviation/target ratio was greater with the most frequent response than with the least frequent response, indicating a greater facility of ESP expression with the pro-bias response. In 3 of these 6 series, the greater degree of psi medition was sufficient to cause this response also to be more correct than the anti -bias response. (9 ref)
