Procedural Justice Training for Police Officers Can Significantly Improve Officer Behavior and Strengthen Community Trust

Strategic Insights -

As communities across the U.S. continue to grapple with public safety and police reform, a new study published in the INFORMS journal Management Science offers compelling evidence for a path forward: procedural justice training for police officers, backed by leadership support, can significantly improve officer behavior and strengthen community trust. The study, conducted in partnership with the Mexico City Police Department between 2017 and 2018, used an innovative "mystery shopper" method to evaluate the impact of procedural justice training on officer behavior. The results showed that training alone is not enough, and sustainable change requires leadership buy-in and systems that integrate procedural justice into how a department operates.
