#6. Beer Goggles
Science Shows...
As it happens, beer goggles are a real live scientific phenomenon. Scientists tested a group of 84 British students with some lime-flavored drinks. Some of those drinks were non-alcoholic, some were spiked with vodka to get the subject good and sauced. We like to think they served these drinks in beakers and graduated cylinders, in true nerd fashion.
In a laboratory simulation of 'cruising for chicks on Facebook after downing a six pack,' the scientists showed the college students photos of both males and females and had students play the scientific method's first documented instance of would you rather. What they discovered was that the students with the spiked drinks found the people in the photos more attractive--even the heterosexual students looking at people of their own gender.
