On September 28, 2019 the Justice Collaboratory welcomed member Prof. Rodrigo Canales (Associate Professor of Organizational Behavior, Yale School of Management) for a talk on "Building Effective, Resilient, and Trusted Police Organizations in Mexico City". Professor Canales discussed his police reform experiment in Mexico City that involved retraining police officers in procedures built around the just treatment of members of the public. This experiment was evaluated through the collection of several types of data to assess its impact on police behavior.
