Aggression in a Prison Setting as a Function of Lunar Phases

Psychol Rep. 1998 Jun;82(3 Pt 1):747-52. doi: 10.2466/pr0.1998.82.3.747.


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.
