A visitor once asked the Nobel Prize–winning physicist Niels Bohr whether he really believed that the horseshoe he’d hung at his country home was lucky. “Of course not,” Bohr said. “But I understand it’s lucky whether you believe in it or not.”
If Bohr couldn’t resist magical thinking, can anyone? One recent study found that even physicists, chemists, and geologists at MIT and other elite schools were instinctively inclined to attach a purpose to natural events. When the researchers subjected the scientists to time pressure (reasoning that this could expose a person’s uncensored biases), they were twice as likely to approve of statements such as “Trees produce oxygen so that animals can breathe” than they were when they had time to respond more deliberately . Such bias may well be deep-seated: another recent study found that, regardless of their parents’ religiosity, 5-to-7-year-old children preferred explanations of events that involved lessons—like “Maggie’s house burned down to teach her not to play with fire anymore” .
