Evidence-based policy in a new era of crime and violence prevention and social justice

The present state of calls for and efforts to implement evidence-based policy provide a powerful foundation for propelling a movement toward bringing about rational, cost-efficient, and humane policies for reducing aggression, crime, and violence. The main aim of this article is to report on new developments in evidence-based policy (EBP)—what we view as giving rise to a new era in crime and violence prevention and social justice. The article describes major advances, both in research and policy, and discusses pressing challenges that confront EBP in crime/violence and justice, drawing on key findings from a new, comprehensive book project. The overall conclusion of the findings is heartening and yet sobering. Research and policy have made substantial progress, but there is much more to be done. The specific details of this work are organized around three questions that are foundational to evidence-based crime/violence and justice policy today: (a) How is research contributing to and guiding EBP? (b) What are productive and new ways to think about EBP? and (c) What are strategies for promoting greater use of EBP?
