The werewolf myth is one that has become iconic in popular culture. There are dozens (at least) of films about the full moon turning human beings into monsters from An American Werewolf in Paris to the classic from the 1950s, The Curse of the Werewolf. The legend of the werewolf can be traced back deep into literature and myth from around the world. In The Metamorphoses, Ovid writes of King Lycaon who is changed into a werewolf by the gods after eating tainted meat.
Although there is some evidence to suggest that full moons might cause changes in human behaviour, it is mostly anecdotal and too sporadic to be considered factual. For example, in 1978 a study called Human Aggression and the Lunar Synodic Cycle found that in “11,613 cases of aggravated assault in a 5-year period: assaults occurred more often around the full moon.” (source)
More recently, in 2007, Sussex police announced that they found a correlation between the incidence of violence among drinkers in the seaside town of Brighton.
“I compared a graph of full moons and a graph of last year’s violent crimes and there is a trend,” Inspector Andy Parr told the Brighton Argus newspaper. “People tend to be more aggressive generally. I would be interested in approaching the universities and seeing if any of their post-graduates would be interested in looking into it further. This could be helpful to us.” (source)
It should be noted that “in separate findings, [the Brighton] police also found that violence in pubs and nightclubs increased on paydays.”
