Does restorative justice reduce recidivism?
gpt
Yes. 

Sherman, L., Strang, H., Mayo-Wilson, E., Woods, D., & Ariel, B. (2015). Are Restorative Justice Conferences Effective in Reducing Repeat Offending? Findings from a Campbell Systematic Review. Journal Of Quantitative Criminology, 31(1), 1-24. 

Objectives: This paper synthesizes the effects on repeat offending reported in ten eligible randomized trials of face-to-face restorative justice conferences (RJCs) between crime victims, their accused or convicted offenders, and their respective kin and communities. Methods: After an exhaustive search strategy that examined 519 studies that could have been eligible for our rigorous inclusion criteria, we found ten that did. Included studies measured recidivism by 2 years of convictions after random assignment of 1,880 accused or convicted offenders who had consented to meet their consenting victims prior to random assignment, based on 'intention-to-treat' analysis. Results: Our meta-analysis found that, on average, RJCs cause a modest but highly cost-effective reduction in the frequency of repeat offending by the consenting offenders randomly assigned to participate in such a conference. A cost-effectiveness estimate for the seven United Kingdom experiments found a ratio of 3.7-8.1 times more benefit in cost of crimes prevented than the cost of delivering RJCs. Conclusion: RJCs are a cost-effective means of reducing frequency of recidivism.
