Despite decades of policy ideas, pouring millions of dollars into the problem, and a slow pace of gun control measures, the United States hasn’t made much progress on curbing the epidemic of gun violence in our country.

For the past 25 years, Prof. Jens Ludwig of the University of Chicago has examined the questions of: Why does gun violence happen, and is there anything we can do about it?

In his new book, Unforgiving Places: The Unexpected Origins of American Gun Violence, Ludwig—who is director of the University of Chicago Crime Lab—discusses why we've been thinking about the gun violence problem in the wrong ways.

Drawing upon behavioral economics, he explains that most shootings are not premediated; rather, the result of arguments that escalate into violence. Using data-backed interventions, Ludwig introduces new ideas beyond policy and policing to get at the real root causes of gun violence today.
