Everyone has hunches — about friends’ motives, about the stock market, about when to fold a hand of poker and when to hold it. But United States troops are now at the center of a large effort to understand how it is that in a life-or-death situation, some people’s brains can sense danger and act on it well before others’ do.

Experience matters, of course: if you have seen something before, you are more likely to anticipate it the next time. And yet, recent research suggests that something else is at work, too.

Small differences in how the brain processes images, how well it reads emotions and how it manages surges in stress hormones help explain why some people sense imminent danger before most others do.
