Abstract

Prior literature suggests that psi perception may be better when the planetary geomagnetic field is relatively quiet. This possible geomagnetic-psi relationship was analyzed in two ganzfeld psi experiments, one with normal and the other with creatively-talented participants. Both ganzfeld experiments consisted of 32 sessions. The experiment using a normal population resulted in a chance-expected hit rate of exactly 25%; the creative population resulted in a hit rate of 41% (exact binomial p = .016).For the normal population, when psi performance was better, geomagnetic field fluctuations were lower (p < .001, two-tailed). The opposite was observed in the creative population: better psi performance was associated with higher geomagnetic fluctuations (p < .05, two-tailed). Differences in methods of studying geomagnetism-psi relationships are discussed.
