At the Justice Collaboratory, we’ve undertaken a variety of projects involving the study of procedural justice in both legal and community settings. Examples of our legitimacy and procedural justice work include:


Changing the Law to Change Policing: First Steps 

Recent events since the death of George Floyd have brought forth longstanding concerns about the nature of policing in the United States and how it undermines racial equity. As an institution, policing needs significant reconsideration. It is time to rethink the structure and governance of policing. It is also time to engage in a deeper conversation about the meaning of public safety. 


Public Safety Policy

Released ahead of the 2020 presidential election, Re-Imagining Public Safety: Prevent Harm and Lead with the Truth provides recommendations for police reform. This report contains a five-step policy action plan highlighting the critical next steps to advance policing in America.





Our experiment for the New York City Mayor’s Office of Criminal Justice examined perceptions of procedural justice with both NYC community members and its criminal justice workers. Few studies had previously attempted to measure procedural justice on a community level, and had tended to focus on one criminal justice agency at a time. The Justice Collaboratory’s study fulfilled the goal of putting into practice “principles of fairness and procedural justice” by looking into New Yorker’s engagement with the city government.


Principles of Procedurally Just Policing

The Principles of Just Policing report offers a new set of practical guidelines aimed at incorporating procedural justice into policing practices. Written for an audience of policy-makers and policing executives, these guidelines are meant to aide departments in adapting and developing policies that will strengthen legitimacy and trust in interactions with the communities they serve.



Report Of The Facebook Data Transparency Advisory Group

In concert with Facebook, Justice Collaboratory faculty co-directors Tracey Meares and Tom Tyler lead a team of seven independent experts to assess the metrics included in the first two versions of its Community Standards Enforcement Report. This Data Transparency Advisory Group (DTAG) created a final report summarizing its findings.
