Freakonomics

The data also show that smaller offices are more honest than big ones. An office with a few dozen employees generally outpays by 3 to 5 percent an office with a few hundred employees. This may seem counterintuitive. In a bigger office, a bigger crowd is bound to convene around the bagel table, providing more witnesses to make sure you drop your money in the box. But in the big-office/small-office comparison, bagel crime seems to mirror street crime. There is far less street crime per capita in rural areas than in cities, in large part because a rural criminal is more likely to be known (and therefore caught). Also, a smaller community tends to exert greater social incentives against crime, the main one being shame.

The bagel data also reflect how much personal mood seems to affect honesty. Weather, for instance, is a major factor. Unseasonably pleasant weather inspires people to pay at a higher rate. Unseasonably cold weather, meanwhile, makes people cheat prolifically; so do heavy rain and wind. Worst are the holidays. The week of Christmas produces a 2 percent drop in payment rates—again, a 15 percent increase in theft, an effect on the same magnitude, in reverse, as that of 9/11. Thanksgiving is nearly as bad; the week of Valentine’s Day is also lousy, as is the week straddling April 15. There are, however, a few good holidays: the weeks that include the Fourth of July, Labor Day, and Columbus Day. The difference in the two sets of holidays? The low-cheating holidays represent little more than an extra day off from work. The high-cheating holidays are fraught with miscellaneous anxieties and the high expectations of loved ones.

Feldman has also reached some of his own conclusions about honesty, based more on his experience than the data. He has come to believe that morale is a big factor—that an office is more honest when the employees like their boss and their work. He also believes that employees further up the corporate ladder cheat more than those down below. He got this idea after delivering for years to one company spread out over three floors—an executive floor on top and two lower floors with sales, service, and administrative employees. (Feldman wondered if perhaps the executives cheated out of an overdeveloped sense of entitlement. What he didn’t consider is that perhaps cheating was how they got to be executives.)

If morality represents the way we would like the world to work and economics represents how it actually does work, then the story of Feldman’s bagel business lies at the very intersection of morality and economics. Yes, a lot of people steal from him, but the vast majority, even though no one is watching over them, do not. This outcome may surprise some people—including Feldman’s economist friends, who counseled him twenty years ago that his honor-system scheme would never work. But it would not have surprised Adam Smith. In fact, the theme of Smith’s first book, The Theory of Moral Sentiments, was the i

There is a tale, “The Ring of Gyges,” that Feldman sometimes tells his economist friends. It comes from Plato’s Republic. A student named Glaucon offered the story in response to a lesson by Socrates—who, like Adam Smith, argued that people are generally good even without enforcement. Glaucon, like Feldman’s economist friends, disagreed. He told of a shepherd named Gyges who stumbled upon a secret cavern with a corpse inside that wore a ring. When Gyges put on the ring, he found that it made him invisible. With no one able to monitor his behavior, Gyges proceeded to do woeful things—seduce the queen, murder the king, and so on. Glaucon’s story posed a moral question: could any man resist the temptation of evil if he knew his acts could not be witnessed? Glaucon seemed to think the answer was no. But Paul Feldman sides with Socrates and Adam Smith—for he knows that the answer, at least 87 percent of the time, is yes.

Levitt is the first to say that some of his topics—a study of discrimination on The Weakest Link?—border on the trivial. But he has shown other economists just how well their tools can make sense of the real world. “Levitt is considered a demigod, one of the most creative people in economics and maybe in all social science,” says Colin F. Camerer, an economist at the California Institute of Technology. “He represents something that everyone thinks they will be when they go to grad school in econ but usually they have the creative spark bored out of them by endless math—namely, a kind of intellectual detective trying to figure stuff out.”

2. How Is the Ku Klux Klan Like a Group of Real-Estate Agents?

As institutions go, the Ku Klux Klan has had a markedly up-and-down history. It was founded in the immediate aftermath of the Civil War by six former Confederate soldiers in Pulaski, Te

The early Klan did its work through pamphleteering, lynching, shooting, burning, castrating, pistol-whipping, and a thousand forms of intimidation. They targeted former slaves and any whites who supported the blacks’ rights to vote, acquire land, or gain an education. Within barely a decade, however, the Klan had been extinguished, largely by legal and military interventions out of Washington, D.C.

But if the Klan itself was defeated, its aims had largely been achieved through the establishment of Jim Crow laws. Congress, which during Reconstruction had been quick to enact measures of legal, social, and economic freedom for blacks, just as quickly began to roll them back. The federal government agreed to withdraw its occupation troops from the South, allowing the restoration of white rule. In Plessy v. Ferguson, the U.S. Supreme Court gave the go-ahead to full-scale racial segregation.

The Ku Klux Klan lay largely dormant until 1915, when D. W. Griffith’s film The Birth of a Nation—originally titled The Clansman—helped spark its rebirth. Griffith presented the Klan as crusaders for white civilization itself, and as one of the noblest forces in American history. The film quoted a line from A History of the American People, written by a renowned historian: “At last there had sprung into existence a great Ku Klux Klan, a veritable empire of the South, to protect the Southern country.” The book’s author was U.S. president Woodrow Wilson, onetime scholar and president of Princeton University.
