“…Data from four jurisdictions indicate that Black offenders obtain higher average criminal history scores than do White offenders (mean d = .24, standard deviation or SD = .05)-with the range of effect sizes (d = .19-.29) suggesting approximately 79-85 percent overlap between groups (see Cohen, 1988). 1 Criminal history reflects not only the differential participation of racial groups in crime (e.g., Black people being involved in crime-particularly violent/serious crime-at a higher rate than Whites) but also the differential selection of given groups by criminal justice officials (e.g., police decisions about arrest and prosecutor decisions about charging) and by sentencing policies (e.g., minimum mandatories; Blumstein, 1993;Frase, 2009;Tonry and Melewski, 2008;Ulmer, Painter-Davis, and Tinik, 2014). The proportion of racial disparities in crime explained by differential participation versus differential selection is hotly debated (see Frase, 2014;McCord, Widom, and Crowell, 2001) and varies as a function of crime type (e.g., violence vs. drug crimes) and stage of justice processing (e.g., arrest vs. incarceration; Blumstein et al, 1983;Piquero, 2015).…”
