Impact of In-Service Implicit Bias Training: A Study of Attitudinal Changes and Intention to Apply Anti-Bias Techniques

Research points to implicit bias as one factor driving racial disparities in enforcement activities. Addressing implicit bias is essential to promote equity and integrity in policing and to building trust and legitimacy in communities, according to the President’s Task Force on 21 st Century Policing. However, investigations into the efficacy of implicit bias training for police are sparse. This study evaluates in-service implicit bias training, examining the impact on trainees’ knowledge, attitudes, and self-professed likelihood of applying antibias strategies to mitigate the effects of implicit bias. We found significant improvements to officers’ knowledge of how implicit bias works and its consequences, an increased attribution to procedural justice, and officers reported being more likely, following the training, to apply strategies to reduce the effects of implicit bias during encounters with public. Results benefit police departments that seek to reduce unconscious prejudice, ensure impartiality and equity, and develop better relations with minority communities.
