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

SIGNATURE: A workbench for gene expression signature analysis

<p>Abstract</p> <p>Background</p> <p>The biological phenotype of a cell, such as a characteristic visual image or behavior, reflects activities derived from the expression of collections of genes. As such, an ability to measure the expression of these genes provides an opportunity to develop more precise and varied sets of phenotypes. However, to use this approach requires computational methods that are difficult to implement and apply, and thus there is a critical need for intelligent software tools that can reduce the technical burden of the analysis. Tools for gene expression analyses are unusually difficult to implement in a user-friendly way because their application requires a combination of biological data curation, statistical computational methods, and database expertise.</p> <p>Results</p> <p>We have developed SIGNATURE, a web-based resource that simplifies gene expression signature analysis by providing software, data, and protocols to perform the analysis successfully. This resource uses Bayesian methods for processing gene expression data coupled with a curated database of gene expression signatures, all carried out within a GenePattern web interface for easy use and access.</p> <p>Conclusions</p> <p>SIGNATURE is available for public use at <url>http://genepattern.genome.duke.edu/signature/</url>.</p

Mass support for proposals to reshape policing depends on the implications for crime and safety

Research Summary This paper presents novel survey and experimental evidence that reveals the mass public's interpretation of movements to reform, defund, and abolish the police. We find strong support for police reform, but efforts to defund or abolish generate opposition both in terms of slogan and substance. While these differences cannot be explained by differing beliefs about each movement's association with violent protests, racial makeup, or specific programmatic changes, efforts to defund and abolish the police appear unpopular because they seek reduced involvement of police in traditional roles and cuts in police numbers. Policy Implications Our findings suggest that public support for changes to American policing is contingent on the perceived implications for crime and public safety. Proposals like defunding and abolition are therefore unlikely to succeed at the national level. Viable police reform may instead require proposals that target changing how police departments and their officers operate rather than lowering police budgets or decreasing police involvement in responding to crime and calls for service
