Men know the struggles of asking a woman to come home with them at a bar, but very rarely has it been done in the name of science. An experiment in 1978 had a man go up to 16 women on a college campus and ask a single question: “I have been noticing you around campus. I find you attractive. Would you go to bed with me tonight?” All 16 women declined. However, a parallel experiment was performed with a woman asking the question, and only 4 of the 16 men asked said no, and only for reasons of prior commitments. Russell Clark, the mind behind the experiment, wanted to discover how the different sexes reacted to blatant advances. As he demonstrated, women and men react very differently to the prospect of sex, apparently because of the amount of energy each gender has to invest into the act.
