He also said that he thought that the quotes were being misused, and that he still stood by the blurb for my book—the blurb stating that my research represented “the most extensive, thorough, and sophisticated study we have on the effects of loosening gun control laws.” 7 Are the CBS and Voter News Service polls accurately reflecting how gun ownership rates vary across states? Douglas Weil: But the most important information is that the Voter News Service, which conducted the 1996 poll has said the poll cannot be used in the manner Dr. Lott used it. It cannot be used to say anything about gun ownership in any state, and it cannot be used to compare gun ownership to the earlier 1988 voter poll. (“More Guns, Less Crime? A Debate between John Lott, Author of More Guns, Less Crime, and Douglas Weil, Research Director of Handgun Control, Inc.,” an on-line debate sponsored by Time magazine, transcript from July 1, 1998) Statistics from the CBS and Voter News Service exit polls (discussed in chapters 3 and 5) were originally “weighted” by these organizations to reflect the share of different racial, sex, and age groups in the national population.

The typical gun buyback program yields fewer than 1,000 guns—which translates into an expectation of less than one-tenth of one homicide per buyback. Not enough, that is, to make even a sliver of impact on the fall of crime. Then there is an opposite argument—that we need more guns on the street, but in the hands of the right people (like the high-school girl above, instead of her mugger). The economist John R. Lott Jr. is the main champion of this idea. His calling card is the book More Guns, Less Crime, in which he argues that violent crime has decreased in areas where law-abiding citizens are allowed to carry concealed weapons. His theory might be surprising, but it is sensible. If a criminal thinks his potential victim may be armed, he may be deterred from committing the crime. Handgun opponents call Lott a pro-gun ideologue, and Lott let himself become a lightning rod for gun controversy.

“You wouldn’t know that he was a ‘right-wing’ ideologue from the class….There were a group of us students who would try to take any class that he taught. Lott finally had to tell us that it was best for us to try and take classes from other professors more to be exposed to other ways of teaching graduate material.” Then there was the troubling allegation that Lott actually invented some of the survey data that support his more-guns/less-crime theory. Regardless of whether the data were faked, Lott’s admittedly intriguing hypothesis doesn’t seem to be true. When other scholars have tried to replicate his results, they found that right-to-carry laws simply don’t bring down crime. Consider the next crime-drop explanation: the bursting of the crack bubble. Crack cocaine was such a potent, addictive drug that a hugely profitable market had been created practically overnight.

One of the unfortunate aspects of the University of Chicago at that time, one that is thankfully no longer the case, was that there was an undue tolerance for scholars who would spout the Chicago School traditional lines, loudly and frequently. One example was the economist John Lott, who had strung together a series of visiting appointments allowing him to be at the university for several years. Lott is most famous for writing a book entitled More Guns, Less Crime. As the title suggests, the thesis of the book is that if we just made sure every American was armed at all times, no one would dare commit a crime, a claim that other researchers have strongly disputed.§ Lott was a frequent attendee and active participant at workshops. His style resembled that of a pit bull. At this workshop, Lott was present and looking annoyed, so I hoped he was not packing a gun.

This topic was chosen, Brock explains, because with “a squish like Bush in the White House . . . the political reality [was] that the conservative agenda could be best advanced by renegade conservatives on Capitol Hill” (79f). Needless to say, paying fresh-faced former college students lots of money to write articles that serve political needs is not the best way to get accurate information. But is accurate information the goal? Look at John Lott, a “resident scholar” at the American Enterprise Institute—the same right-wing think tank that promoted The Bell Curve. Lott’s book More Guns, Less Crime claimed that his scientific studies had found that passing laws to allow people to carry concealed weapons actually lowered crime rates. As usual, the evidence melted away upon investigation, but Lott’s errors were more serious than most. Not content to simply distort the data, Lott fabricated an entire study which he claimed showed that in 97% of cases, simply brandishing a gun would cause an attacker to flee.

Bush administration’s controversial “torture memo” legalizing the American government’s brutalization of terror suspects. Without the rigorous peer-reviewed standards required by prestigious academic publications, the Olin Foundation was able to inject into the mainstream a number of works whose scholarship was debatable at best. For example, Olin Foundation funds enabled John R. Lott Jr., then an Olin fellow at the University of Chicago, to write his influential book More Guns, Less Crime. In the work, Lott argued that more guns actually reduce crime and that the legalization of concealed weapons would make citizens safer. Politicians advocating weaker gun control laws frequently cited Lott’s findings. But according to Adam Winkler, the author of Gunfight, Lott’s scholarship was suspect. Winkler wrote that “Lott’s claimed source for this information was ‘national surveys,’ ” which under questioning he revised to just one survey that he and research assistants had conducted.

The Israelis and Swiss are armed to the teeth but have low rates of violent personal crime, and among American states, Maine and North Dakota have the lowest homicide rates but almost every home has a gun.25 The idea that guns increase lethal crime, though certainly plausible, has been so difficult to prove that in 1998 the legal scholar John Lott published a book of statistical analyses with a title that flaunts the opposite conclusion: More Guns, Less Crime. Even if he is wrong, as I suspect he is, it is not so easy to show that more guns mean more crime. As for discrimination and poverty, again it is hard to show a direct cause-and-effect relationship. Chinese immigrants to California in the nineteenth century and Japanese-Americans in World War II faced severe discrimination, but they did not react with high rates of violence. Women are poorer than men and are more likely to need money to feed children, but they are less likely to steal things by force.
