(Press-News.org) In recent years, many police departments have mandated or encouraged anti-bias training. This has occurred in response to government-imposed measures such as consent decrees or as a proactive attempt to enhance public perceptions of police following actions that have raised concerns about racially motivated and other discriminatory practices. In a new study, researchers evaluated the effectiveness of an anti-bias training intervention in one Californian jurisdiction. The study found that officers who received the training had improved performance scores (measured by Body Worn Camera footage), decreased disparity in how they treated different groups of people, and fewer discrimination-based complaints. Results were small but significant.
The study, by researchers at Washington State University (WSU) and RTI International, is published in Policing: An International Journal.
Through anti-bias training programs, police departments seek to promote fairness in police decision making, enhance public perceptions of police, and ultimately improve interactions between police and community members. Many programs target bias, with two methods used most frequently: implicit bias training (classroom-based training with lectures on the science of bias, strategies to recognize bias, and scenarios for practicing strategies) and counter-bias training (simulation-based training in which officers respond to scenarios to facilitate their recognition of biases in behavior and practice unbiased decision making).
“Despite concerns around bias and departmental commitments to anti-bias training, there is limited evidence on the impact of the trainings on officers’ behavior and decision making in interactions with the community,” explains Lois James, Assistant Dean of Research at WSU’s College of Nursing, who led the study. James is an expert whose work is promoted by the NCJA Crime and Justice Research Alliance, which is funded by the National Criminal Justice Association.
Between 2019 and 2021, James and her colleagues evaluated the effects of an anti-bias intervention that combined implicit and counter-bias training on two distinct outcomes: officers’ performance as measured by coded body worn camera (BWC) footage of encounters with community members and discrimination-based citizen complaints issued against the police.
Fifty patrol officers from the Sacramento Police Department were randomly selected to participate in the anti-bias intervention. Before and after the intervention, researchers coded a random selection of BWC videos from the intervention group and from a control group of officers who did not take part in the training to assess police performance in interactions with the public. They also collected discrimination-based complaints by community members before and after the intervention for both groups.
Officers who participated in the anti-bias training had a small but significant increase (approximately 5%) in performance scores compared to officers who did not take part in the training. In addition, officers who were trained had a reduction (approximately 50%) in discrimination-based complaints compared to officers who were not trained.
The improvements in officers’ performance scores appeared to be driven by reductions in disparities in how officers treated community members who were suffering homelessness. The study did not find disparities in how officers interacted with community members based on race, but disparities were observed for gender, with officers receiving lower performance scores in interactions with men than with women.
“Although our results are from a single municipal police department, ours is the first study to suggest that anti-bias training could have a positive behavioral impact on officers’ behaviors during interactions with the public and on public perceptions of biased treatment by officers,” notes Stephen James, Assistant Professor in WSU’s Elson S. Floyd College of Medicine, who coauthored the study. “As such, this is a tentatively encouraging step forward in demonstrating the effectiveness of anti-bias training.”
“However, our findings should be interpreted with caution and do not necessarily mean that anti-bias training will be successful in improving police interactions with the public,” adds Renée Jean Mitchell, who was a senior research scientist at RTI when she coauthored the study. “Other factors could contribute to these findings and so we encourage more research on this important issue.”
Moreover, the authors caution that the combined effects of the COVID-19 pandemic and the civil unrest of 2020 might have influenced results in ways that are difficult to account for, even with a no-training control group. The way police in the jurisdiction studied dealt with these factors might have differed from how other departments dealt with them, so the findings might not generalize to other jurisdictions.
The study was funded by the National Institute of Justice.
Anti-bias police training improved performance and reduced discrimination-based complaints significantly

Massive 2022 eruption reduced ozone levels
When the Hunga Tonga-Hunga Ha’apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered tsunamis in Tonga, Fiji, New Zealand, Japan, Chile, Peru and the United States. It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere, according to a recent study published in the Proceedings of the National ...
Remarkably detailed view of “teenage galaxies” from just 2 to 3 billion years after the Big Bang revealed by JWST
Pasadena, CA—Galaxies that formed just 2 to 3 billion years after the Big Bang are unusually hot and glow with light from surprising elements, like nickel, according to new work led by Carnegie’s Gwen Rudie and Northwestern University’s Allison Strom. Studying “teenage galaxies” from the ancient universe can teach scientists about how these massive systems of stars mature and evolve. Their findings, published in The Astrophysical Journal Letters, are part of the CECILIA (Chemical Evolution Constrained using Ionized Lines in Interstellar Aurorae) ...
Litigating the Pandemic
When the COVID-19 pandemic spread across the United States, healthcare workers faced new demands, childcare and grocery store workers became essential workers, businesses shut down, and churches and school doors closed. The pandemic also arrived amidst protests over police violence. Deep partisan divisions and record natural disasters amplified these challenges. The national government offered new funding for businesses and individuals and public health guidance, and local governments issued guidelines for gathering in public. Litigating the Pandemic (University of Pennsylvania Press, 2023), a new book by Susan Sterett, professor ...

Big-data study explores social factors affecting child health
A team led by researchers at Weill Cornell Medicine has used an AI-based approach to uncover underlying patterns among the conditions in which people are born, grow, live, work, and age, termed social determinants of health (SDoH), and then linked each pattern to children’s health outcomes. Compared with traditional approaches, the strategy, in principle, provides a more objective and comprehensive picture of potential social factors that affect child health, which in turn, can enable better targeted interventions. As reported Oct. 16 in JAMA Pediatrics, the researchers analyzed data on more than 10,500 American children, in communities across 17 U.S. ...
