The past and future of U.S. prison policy: Twenty-five years after the Stanford Prison Experiment.

In this article, the authors reflect on the lessons of their Stanford Prison Experiment, some 25 years after conducting it. They review the quarter century of change in criminal justice and correctional policies that has transpired since the Stanford Prison Experiment and then develop a series of reform-oriented proposals drawn from this and related studies on the power of social situations and institutional settings that can be applied to the current crisis in American corrections.
