Steven Dubner - Freakonomics Страница 24

Drawn from a pair of “smart” databases, here is a sampling of today’s high-end names. Some of them, as unlikely as it seems, are bound to become tomorrow’s mainstream names. Before you scoff, ask yourself this: do any of them seem more ridiculous than “Madison” might have seemed ten years ago?

Obviously, a variety of motives are at work when parents consider a name for their child. They may want something traditional or something bohemian, something unique or something perfectly trendy. It would be an overstatement to suggest that all parents are looking—whether consciously or not—for a

“smart” name or a “high-end” name. But they are all trying to signal something with a name, whether the name is Winner or Loser, Madison or Amber, Shithead or Sander, DeShawn or Jake. What the California names data suggest is that an overwhelming number of parents use a name to signal their own expectations of how successful their children will be. The name isn’t likely to make a shard of difference. But the parents can at least feel better knowing that, from the very outset, they tried their best.

EPILOGUE:

Two Paths to Harvard

And now, with all these pages behind us, an early promise has been confirmed: this book indeed has no “unifying theme.”

But if there is no unifying theme to Freakonomics, there is at least a common thread running through the everyday application of Freakonomics. It has to do with thinking sensibly about how people behave in the real world. All it requires is a novel way of looking, of discerning, of measuring. This isn’t necessarily a difficult task, nor does it require supersophisticated thinking. We have essentially tried to figure out what the typical gang member or sumo wrestler figured out on his own (although we had to do so in reverse).

Will the ability to think such thoughts improve your life materially? Probably not. Perhaps you’ll put up a sturdy gate around your swimming pool or push your real-estate agent to work a little harder. But the net effect is likely to be more subtle than that. You might become more skeptical of the conventional wisdom; you may begin looking for hints as to how things aren’t quite what they seem; perhaps you will seek out some trove of data and sift through it, balancing your intelligence and your intuition to arrive at a glimmering new idea. Some of these ideas might make you uncomfortable, even unpopular. To claim that legalized abortion resulted in a massive drop in crime will inevitably lead to explosive moral reactions. But the fact of the matter is that Freakonomics-style thinking simply doesn’t traffic in morality. As we suggested near the beginning of this book, if morality represents an ideal world, then economics represents the actual world.

The most likely result of having read this book is a simple one: you may find yourself asking a lot of questions. Many of them will lead to nothing. But some will produce answers that are interesting, even surprising. Consider the question posed at the beginning of this book’s penultimate chapter: how much do parents really matter?

The data have by now made it clear that parents matter a great deal in some regards (most of which have been long determined by the time a child is born) and not at all in others (the ones we obsess about). You can’t blame parents for trying to do something—anything—to help their child succeed, even if it’s something as irrelevant as giving him a high-end first name.

But there is also a huge random effect that rains down on even the best parenting efforts. If you are in any way typical, you have known some intelligent and devoted parents whose child went badly off the rails. You may have also known of the opposite instance, where a child succeeds despite his parents’ worst intentions and habits.

Recall for a moment the two boys, one white and one black, who were described in chapter 5. The white boy who grew up outside Chicago had smart, solid, encouraging, loving parents who stressed education and family. The black boy from Daytona Beach was abandoned by his mother, was beaten by his father, and had become a full-fledged gangster by his teens. So what became of the two boys?

The second child, now twenty-seven years old, is Roland G. Fryer Jr., the Harvard economist studying black underachievement.

The white child also made it to Harvard. But soon after, things went badly for him. His name is Ted Kaczynski.

ADAM SMITH is still well worth reading, of course (especially if you have infinite patience); so too is Robert Heilbroner’s The Worldly Philosophers (New York: Simon & Schuster, 1953), which contains memorable profiles of Smith, Karl Marx, Thorstein Veblen, John Maynard Keynes, Joseph Schum-peter, and other giants of economics.

THE BAGEL MAN: Paul Feldman was looking for a research economist to take an interest in his data, and brought himself to Steven Levitt’s attention. (Several other scholars had passed.) Levitt and then Dubner subsequently visited Feldman’s bagel operation near Washington, D.C. Their research led to an article that was substantially similar to the version of the story published here: Stephen J. Dubner and Steven D. Levitt, “What the Bagel Man Saw,” The New York Times Magazine, June 6, 2004. Levitt is also writing an academic paper about Feldman’s bagel operation. / 47 The “Beer on the Beach” study is discussed in Richard H. Thaler, “Mental Accounting and Consumer Choice,” Marketing Science 4 (Summer 1985), pp. 119–214; also worth reading is Richard H.
