Aggression in a Prison Setting as a Function of Lunar Phases

Abstract

Previous studies of the possible effects of the moon's phases upon human behavior initially yielded contradictory results and later more consistently negative results. The present study capitalized on a captive deviant sample prone to aggression, one of the earlier targeted behaviors. A Pearson correlation between number of reported incidents in a Texas prison and the amount of lunar luminosity (lunar phases) yielded no significant correlation.
