In one of the many wonderful moments in Think Like a Freak: The Authors of Freakonomics Offer to Retrain Your Brain , Steven Levitt and Stephen Dubner ask the question: “Who is easier to fool—kids or adults?” The obvious answer, of course, is kids. The cliché is about taking candy from a baby, not a grown man. But instead of accepting conventional wisdom as fact, the two sit down with the magician Alex Stone—someone in the business of fooling people—and ask him what he thinks. And his answer? Adults.

Stone gave the example of the staple of magic tricks, the “double lift,” where two cards are presented as one. It’s how a magician can seemingly bury a card that you have selected at random and then miraculously retrieve it. Stone has done the double lift countless times in his career, and he says it is kids—overwhelmingly—who see through it. Why? The magician’s job is to present a series of cues—to guide the attention of his audience—and adults are really good at following cues and paying attention. Kids aren’t. Their gaze wanders. Adults have a set of expectations and assumptions about the way the world works, which makes them vulnerable to a profession that tries to exploit those expectations and assumptions. Kids don’t know enough to be exploited. Kids are more curious. They don’t overthink problems; they’re more likely to understand that the basis of the trick is something really, really simple. And most of all—and this is my favorite—kids are shorter than adults, so they quite literally see the trick from a different and more revealing angle.

Think Like a Freak is not a book about how to understand magic tricks. That’s what Dubner and Levitt’s first two books—Freakonomics and SuperFreakonomics—were about. It’s about the attitude we need to take towards the tricks and the problems that the world throws at us. Dubner and Levitt have a set of prescriptions about what that attitude comes down to, but at its root it comes down to putting yourself in the mind of the child, gazing upwards at the double lift: free yourself from expectations, be prepared for a really really simple explanation, and let your attention wander from time to time.

The two briefly revisit their famous argument from their first book about the link between the surge in abortions in the 1970s and the fall in violent crime twenty years later. Their point is not to reargue that particular claim. It is to point out that we shouldn’t avoid arguments like that just because they leave us a bit squeamish. They also tell the story of the Australian doctor Barry Marshall, who overturned years of received wisdom when he proved that ulcers are caused by gastric bacteria, not spicy food and stress. That idea was more than heretical at first. It was absurd. It was the kind of random idea that only a child would have. But Dubner and Levitt’s point, in their utterly captivating new book, is that following your curiosity—even to the most heretical and absurd end—makes the world a better place. It is also a lot of fun.
