Our happy hour fact to amaze your drinking buddies with.

Monogamous societies drink a lot more than polygamous societies do.

University of Leuven economists Mara Squicciarini and Jo Swinnen have just published a working paper which makes the observation that modern polygamous societies -- chiefly parts of the Muslim world and Mormon fundamentalists -- are strictly dry.

The economists also went back into history and found that when societies shift from being polygamous to monogamous they tend to consume more alcohol. In fact, they found that "drunkenness," in particular, is correlated with monogamy.

Obvious conclusion being that one has to get pretty sloshed to bear coming home to the same person every night.
