Many clinicians believe there may be more emergency room visits during a full moon. Some refer to this phenomena as “full moon madness”. World Journal of Surgery published the results of a survey in 2011 that found “more than 40% of medical staff believe that lunar phases can affect human behavior, even though most studies find no direct correlation between the full moon and hospital admission rates.”
These types of false associations are a common consequence of the human mind’s skill at rationalization and pattern formation. It is why humans invented science: we need objective measurement to be sure we are not fooling ourselves or being fooled by others. This association has been addressed in several published studies, with the majority, and in particular those with better data, showing no association.
