Geophysical Variables and Behavior: XXXI. Global Geomagnetic Activity during Spontaneous Paranormal Experiences: A Replication

A retrospective analysis was completed of the global geomagnetic activity (aa indices) for the day, month, and year in which subjective experiences of telepathy-clairvoyance ( n — 57), precognition ( n = 56), and post mortem ( n = 74) phenomena were reported to have occurred. All of the experiences referred to death, sudden illness, or intense crisis to members of the family or to friends. The experiences were obtained from a series of first-hand reports from FATE magazine and involved all cases that contained the day, month, and year (1920 through 1967) of occurrence. Days on which telepathy-clairvoyance experiences occurred displayed significantly much lower geomagnetic activity (aa = 13.5 ± 10.9) than days on which the precognition (25.5 ± 23.1) and postmortem (26.4 ± 19.1) cases occurred. The aa values for the days on which the telepathy-clairvoyance experiences occurred were also significantly less than the average geomagnetic activity for the months or years in which the experiences occurred. This was not evident for the other types of cases. Results for telepathic-clairvoyance are similar in both direction and magnitude to those from two other data sources. We conclude that such phenomena should be considered within the framework of behavioral epidemiology.
