title: Atmospheric electromagnetism: attempted replication of the correlation between natural sferics and ESP.
abstract: In a previous study a negative correlation was found between the natural sferics activity and scores on an ESP task. We attempted a replication in three studies with 37, 100, and 68 participants. In these studies ESP scores and the level of sferics activity were not significantly correlated. The result for all combined data is significant but with a quite low effect size. Other trends in the data could not be confirmed.
