Following this persistent pattern of beliefs, there is a considerable literature in psychology and medicine that investigates for a moon effect on human behavior. Some of these studies find significant relations, for example individual studies find that homicides, hospital admissions, and crisis incidents peak in the days around the full moon. However, reviews and meta-analyses of the literature have generally been negative. Rotton and Kelley (1985) examines and aggregates the evidence of 37 studies, and concludes that lunar phase influences are “much ado about nothing.”.
