When criminal justice expert Jennifer Doleac thinks about reform, she's not just hopeful, she's optimistic. 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 shifting the incentives people face - even in ways that might seem negligible - 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.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. By shifting focus from the enormity of the problem to the power of small 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 revolutionise criminal justice reform and create the society we want and need.
