Evaluation of Simulation vs. Classroom-Based Implicit Bias Training to Improve Police Decision Making and Enhance the Outcomes of Police-Citizen Encounters, California, 2019-2021

This study evaluated the impact of implicit bias and counter bias training interventions for improving police behavior and public perceptions of bias. A random selection of Body Worn Camera (BWC) videos from a large and diverse municipal agency were scored before and after training using a validated tool for coding police behavior. The variables coded from BWC videos were compiled into Body Worn Camera Data (DS1) and include demographic details on citizens and officers, circumstances of the incident, and the behavior of both the officer and citizen. During pre- and post- intervention measurement periods, "discrimination"-based community member complaints were also collected. Information about these complaints including the type, incident date, and complaint findings was compiled into Complaints Data (DS2).
