Men on a scary bridge rated a stranger more attractive than men on a safe one
In a 1974 field experiment, men who had just crossed a swaying, high suspension bridge rated a female interviewer as more attractive and were more likely to call her later than men who crossed a low, solid bridge. Their bodies were aroused by fear, but they misread that arousal as attraction instead. The study became a classic demonstration that we often don't know why we feel what we feel, only that we feel it.
