Anyone familiar with the gun debate has heard the talking points of the National Rifle Association and other gun rights advocates: “Carrying a gun for self-defense makes you safer.” Or: “If only more ordinary citizens were armed, they could stop mass shootings.” As we’ve shown in our reporting, these arguments don’t stand up to scrutiny. After the massacre at Sandy Hook Elementary School, David Hemenway, director of the Harvard Injury Control Research Center, commented on another long-running assertion from the gun lobby: “There is no evidence that having more guns reduces crime,” he told the New York Times.
Yet, Hemenway says that some in the media have continued to treat such assertions as legitimate points of debate. That leaves the public thinking, “Okay, so there’s disagreement on this,” he says. It occurred to Hemenway that this was a familiar problem, so he set about surveying a wide range of experts on guns—modeling his project after a game-changing 2010 study on climate change, which found that 97 percent of researchers believe that humans are responsible for global warming. Hemenway’s team at Harvard went through about 1,200 articles on firearms published since 2011 in peer-reviewed journals focused on public health, public policy, sociology, and criminology. In May 2014, Hemenway began sending monthly surveys to the authors of these articles—upwards of 300 people—with questions concerning firearm use, background checks, and other gun policies. The Harvard team has completed nine surveys so far, with about 100 researchers responding to each: They show that a clear majority of experts do not buy the NRA’s arguments.
Hemenway plans to compile the results for a journal article later this year (see the growing dataset here). Here are some of the findings:
