Beliefs about minority representation in policing and support for diversification

Diversification of police forces is widely promoted as a reform for reducing racial disparities in police-civilian interactions and increasing police legitimacy. Despite these potential benefits, nearly every municipal police department in the United States remains predominately White and male. Here, we investigate whether the scale and persistence of minority underrepresentation in policing might partly be explained by a lack of support for diversification among voters and current police officers. Across two studies (N = 2, 661) sampling the US adult population and residents from a city with one of the least representative police forces in the country, individuals significantly overestimate officer diversity at both the local and national levels. We find that correcting these biased beliefs with accurate information reduces trust in police and increases support for hiring new officers from underrepresented groups. In the municipal sample, these corrections also cause an increase in residents' willingness to vote for reforms to diversify their majority White police department. Additional paired decision-making experiments (N = 1, 663) conducted on these residents and current police officers demonstrate that both prefer hiring new officers from currently underrepresented groups, independent of civil service exam performance and other hiring criteria. Overall, these results suggest that attitudes among voters and police officers are unlikely to pose a major barrier to diversity reforms.

What do you see? Understanding perceptions of police use of force videos as a function of the camera perspective

Some research suggests that video-recorded police incidents may be subject to a camera perspective bias. This study examined whether the camera angle of a recorded police use of force encounter influenced interpretation of the video. Participants (n = 330) viewed a video-recorded simulated use of force scenario in one of four camera angle conditions (body worn camera, bystander camera, security camera, all three camera angles), and then rated the conduct of the police officer and the subject. Participants' attitudes towards the police and legal system were also examined. Results indicated that camera angle did not directly impact viewers' judgment of the scenario, but pre-existing biases about the police guided their interpretations of certain camera angles. Importantly, however, this was not the case for those who viewed the body worn camera angle. These results help us understand the implications of relying on video recordings of police incidents.

Highly public anti-Black violence is associated with poor mental health days for Black Americans

Highly public anti-Black violence in the United States may cause widely experienced distress for Black Americans. This study identifies 49 publicized incidents of racial violence and quantifies national interest based on Google searches; incidents include police killings of Black individuals, decisions not to indict or convict the officer involved, and hate crime murders. Weekly time series of population mental health are produced for 2012 through 2017 using two sources: 1) Google Trends as national search volume for psychological distress terms and 2) the Behavioral Risk Factor Surveillance System (BRFSS) as average poor mental health days in the past 30 d among Black respondents (mean weekly sample size of 696). Autoregressive moving average (ARMA) models accounted for autocorrelation, monthly unemployment, season and year effects, 52-wk lags, news-related searches for suicide (for Google Trends), and depression prevalence and percent female (for BRFSS). National search interest varied more than 100-fold between racial violence incidents. Black BRFSS respondents reported 0.26 more poor mental health days during weeks with two or more racial incidents relative to none, and 0.13 more days with each log₁₀ increase in national interest. Estimates were robust to sensitivity tests, including controlling for monthly number of Black homicide victims and weekly search interest in riots. As expected, racial incidents did not predict average poor mental health days among White BRFSS respondents. Results with national psychological distress from Google Trends were mixed but generally unsupportive of hypotheses. Reducing anti-Black violence may benefit Black Americans' mental health nationally.

A Behavioral Analysis of Two Strategies to Eliminate Racial Bias in Police Use of Force

Structural racism is rooted in American social systems that were supposedly designed to promote citizens' right to life, liberty, and the pursuit of happiness. Social systems like policing, for example, are built on a foundation of discriminatory practices designed to disenfranchise Black, Indigenous, and people of color (BIPOC). One of the most recent visible examples of racially biased policing is the excessive use of force by officers toward BIPOC. In response, advocates, policy makers, and researchers have sought solutions. Police use-of-force reforms such as body-worn cameras (BWCs) and implicit bias training (IBT) have become popular and are currently being applied in many police departments across the country. However, evidence supporting the effectiveness of these reform strategies to reduce the use of force is mixed, and further evaluations are needed to understand why these strategies are purported to be an effective solution. The purpose of the current review is to ignite future empirical evaluations of use-of-force reform. Following a summary of the research conducted to date on BWCs and IBT, we will conclude with a brief discussion of how behavior analysts might improve and foster strategies that are efficacious. Our ultimate goal is to leave the reader with an understanding of where the data have taken us thus far and how behavior analysts and others can contribute to the reduction and eradication of the discriminatory practices present in policing and other social systems.

Quantifying Public Interest in Police Reforms by Mining Internet Search Data Following George Floyd's Death

BACKGROUND

The death of George Floyd while in police custody has resurfaced serious questions about police conduct that result in the deaths of unarmed persons.

OBJECTIVE

Data-driven strategies that identify and prioritize the public's needs may engender a public health response to improve policing. We assessed how internet searches indicative of interest in police reform changed after Mr Floyd's death.

METHODS

We monitored daily Google searches (per 10 million total searches) that included the terms "police" and "reform(s)" (eg, "reform the police," "best police reforms," etc) originating from the United States between January 1, 2010, through July 5, 2020. We also monitored searches containing the term "police" with "training," "union(s)," "militarization," or "immunity" as markers of interest in the corresponding reform topics.

RESULTS

The 41 days following Mr Floyd's death corresponded with the greatest number of police "reform(s)" searches ever recorded, with 1,350,000 total searches nationally. Searches increased significantly in all 50 states and Washington DC. By reform topic, nationally there were 1,220,000 total searches for "police" and "union(s)"; 820,000 for "training"; 360,000 for "immunity"; and 72,000 for "militarization." In terms of searches for all policy topics by state, 33 states searched the most for "training," 16 for "union(s)," and 2 for "immunity." States typically in the southeast had fewer queries related to any police reform topic than other states. States that had a greater percentage of votes for President Donald Trump during the 2016 election searched more often for police "union(s)" while states favoring Secretary Hillary Clinton searched more for police "training."

CONCLUSIONS

The United States is at a historical juncture, with record interest in topics related to police reform with variability in search terms across states. Policy makers can respond to searches by considering the policies their constituencies are searching for online, notably police training and unions. Public health leaders can respond by engaging in the subject of policing and advocating for evidence-based policy reforms.
