Data from 621 experimental sessions carried out in Scotland, United States and Iceland were retrospectively analyzed for a pos­sible connection between psychokinesis (PK) performance and local geomagnetic activity (K-index). Although the study did not find any significant correlation between geomagnetic activity and overall PK performance, the difference in geomagnetic activity on the day prior to the experimental sessions (split via high and low PK score) was marginally significant (p = .08, 2-T). The compound PK effect in the data base yielded a nonsignificant z-score deviation from MCE of 1.27, with a distribution significantly different from a nor­mal distribution (p = .01, 2-T). Furthermore, males did significantly better than females (p = .04, 2-T), and the youngest subjects did marginally better than the oldest subjects (p = .098, 2-T)
