Why Long Prison Sentences Fail to Deter Crime: A Conversation with Economist Jennifer Doleac

This week, guest host Billy Binion welcomes Jennifer Doleac, an economist specializing in crime and public safety. As executive vice president of criminal justice at Arnold Ventures and author of The Science of Second Chances, Doleac shares groundbreaking research that often defies conventional wisdom.

In their conversation, Doleac presents findings that even surprised her. She highlights that long prison sentences are far less effective at deterring crime than commonly believed. Instead, she advocates for prioritizing higher case clearance rates, noting that shockingly few crimes are solved each year.

The discussion also examines the contentious topic of second chances in criminal justice. Doleac cites research showing that offering leniency to first-time defendants can reduce future crime. She further explores why some well-intentioned policies yield unintended, counterproductive results, and how rehabilitation and reentry programs can be improved. The conversation concludes with insights on leveraging economics to align incentives and enhance outcomes in the criminal justice system.
