A multinational survey of nearly 17,000 people, in fifty-three nations, from all parts of the globe, revealed that men and women, or at least the college-age men and women in the sample, were doing a lot of what social scientists and wildlife biologists call “mate poaching.” Roughly half had made at least one attempt, and many of them succeeded. In North America, 62 percent of men, and 40 percent of women, had tried to poach somebody else’s partner for a short-term fling.
