The Science of Second Chances

Freakonomics for criminal justice, The Science of Second Chances presents a groundbreaking approach to criminal justice reform, revealing how small-scale interventions can reduce people’s chances of reoffending and break the incarceration cycle.When criminal justice expert Jennifer Doleac thinks about reform, she’s not just hopeful, she’s optimistic that second chances are possible—for the justice-involved population and the system as a whole. In The Science of Second Chances, she reveals her powerful approach to reducing crime and incarceration. Drawing on cutting-edge economic research and real-world experiments, the book presents a blueprint for reform that runs all the way through the system. Doleac shows how economists like herself approach big, complicated problems as if they were scientists in a lab, carefully testing different approaches and following the data to maximize impact. She explains how shifting the incentives people face can produce dramatic changes in the decisions they make, significantly reducing the number of people cycling through the prison system. From DNA databases that increase the likelihood of catching reoffenders to leniency programs for first-time defendants, she reveals a series of surprising interventions that actually work, along with cautionary tales about great ideas that never panned out.Doleac doesn’t have a “burn it all down” mentality but seeks to empower readers with practical, achievable solutions. She demonstrates that we can have both public safety and a smaller, less intrusive justice system—without waiting for big, structural reforms that might never come. By shifting focus from the enormity of the problem to the power of small, evidence-based changes, she offers a transformative approach to prosecution and punishment. The Science of Second Chances is essential reading for anyone seeking data-driven strategies to revolutionize the criminal justice system and create the society we want and need.
