Why Aren't We Curious About the Things We Want To Be Curious About?

Daniel T. Willingham, a psychologist at the University of Virginia, writes: You can learn anything on the internet, so why do I so often learn things I don't want to know? When I'm surfing the web I want to be drawn in by articles on Europe's political history or the nature of quasars, but I end up reading trivia like a menu from Alcatraz prison. Why am I not curious about the things I want to be curious about? Curiosity feels like it's outside your control, and trying to direct it sounds as ill conceived as forcing yourself to find a joke funny. But if you understand what prompts curiosity, you may be able to channel it a little better. Across evolutionary time, curious animals were more likely to survive because they learned about their environments; a forager that occasionally skipped a reliable feeding ground to explore might find an even better place to eat. Humans, too, will forgo a known payoff to investigate the unknown. In one experiment, subjects were asked to choose one of four photos, each carrying some chance of paying a cash prize. Photos repeated, so subjects learned to pick the best-paying, but when a novel photo popped up, they chose it more often than the odds dictated they should. This preference for novelty is, of course, the reason manufacturers periodically tweak product packaging and advertising. But it's good to know about your environment even if it doesn't promise a reward right now; knowledge may be useless today, but vital next week. Therefore, evolution has left us with a brain that can reward itself; satisfying curiosity feels pleasurable, so you explore the environment even when you don't expect any concrete payoff. Infants prefer to look at novel pictures compared with familiar ones. Preschoolers play longer with a mechanical toy if it's difficult to deduce how it works.
