Jens Ludwig, director of the University of Chicago Crime Lab, presented findings at UC Berkeley’s Goldman School of Public Policy challenging the assumption that gun violence is typically premeditated. He cited evidence that roughly 80% of gun homicides result from brief, unplanned escalations during everyday disputes. Ludwig highlighted the human cost, noting that behind every statistic lies a family’s loss, as illustrated by the 2007 killing of Amadou Cisse, a University of Chicago graduate student.

Ludwig’s research integrates behavioral economics to identify scalable, cost-effective tools for reducing gun violence. He pointed to programs like 'Becoming a Man,' a school-based counseling initiative that teaches teenage boys to pause and reflect in high-pressure moments. Randomized trials showed the program cut violent-crime arrests among participants by up to 50%, demonstrating that progress can be made without sweeping policy changes.

The lecture, part of the 2026 Wildavsky Lecture in Public Policy, also explored urban design interventions such as greening vacant lots to deter crime. Ludwig emphasized that these measures, combined with de-escalation training for law enforcement, offer immediate public-safety benefits. His book, 'Unforgiving Places: The Unexpected Origins of American Gun Violence,' argues that both political parties have misdiagnosed the root causes of gun violence.

Introduced by Goldman School Dean David Wilson and moderated by Professor Steve Raphael, Ludwig’s talk underscored the role of rigorous research in shaping effective crime policy. Raphael noted Ludwig’s pioneering work in applying machine learning to criminal justice and his leadership in building foundational datasets linking justice and social systems to inform policy decisions.
