No. 67: Jan-Feb 1990
"Several recent reports have indicated significant relations between extrasensory perception (ESP) experiences and performances and the Earth's geomagnetic field (GMF) activity. ESP experiences are reported more frequently, and accuracy of laboratory ESP is more accurate, on days of relatively quiet GMF activity. On the other hand, there are indications that a complementary paranormal process, psychokinesis, may be enhanced by high GMF activity. We conducted retrospective analyses of possible relations between GMF activity and (a) electrodermal activity (as an index of sympathetic autonomic activity), (b) rate of hemolysis of human red blood cells in, (c) attempted distant mental (i.e., psychokinetic) influence of electrodermal activity, and (d) attempted distant mental (psychokinetic) influence of rate of hemolysis. For each of these four measures, high activity was associated with high GMF values, while low activity was associated with low GMF values. The relations were statistically significant for three of the four analyses and showed a consistent trend in the fourth."
