In the most recent issue of the Journal of Scientific Exploration, Peter Sturrock and James Spottiswoode report another confirmation of a lunar phase relationship with psi perception performance. Their paper is entitled "Time-series power spectrum analysis of performance in free response anomalous cognition experiments." Their analysis was based on 3,325 free response trials.
The reason I mention this finding and the one recently published by Eckhard Etzold is because over 10 years ago I published two articles on this topic, both finding lunar phase relationships with psi performance, one based on casino payout data. At the time no one paid much attention to those reports (except for a few skeptics, who felt that mixing lunar effects with psi in the casino was further justification for simply dismissing this realm of research). So it is gratifying to see that independent analyses are now finding the same result.
