The mystery of “beer goggles” -- the phenomenon by which people find opposite sex more attractive after just a few alcoholic drinks -- has finally been solved.
Researchers at Roehampton University claim to have found that the beer goggles effect all comes down to symmetry, where one side mirrors the other, or people's perception of symmetry after a couple of hours in a bar.
In other words, alcohol dulls the drinker's ability to recognise cockeyed, asymmetrical faces. “Alcohol affects our innate human ability to choose a mate. We tend to prefer faces that are symmetrical,” team leader Lewis Halsey said.
