Race and Risk Assessment
Risk-assessment has become all the rage in American criminal justice. In jurisdictions across the country, criminal-justice officials are utilizing increasingly sophisticated risk-assessment tools, which can be used to predict a given offender’s likelihood to reoffend based on his criminal history and a number of other variables. These predictive evaluations can be brought to bear at several important decisional points in the criminal process: pretrial release, diversion into treatment, sentencing, and others.
Although risk assessment has been widely applauded for its potential to support increased efficiency in the use of scarce criminal-justice resources, a recurring criticism has been that leading risk-assessment tools have built-in racial biases. A particular concern has been the heavy reliance on criminal history; to the extent that criminal history reflects biased actions by police or others in the past, then predictions based on that history may tend to overestimate the relative risk posed by minority defendants. Thus, for instance, a black defendant and a white defendant whose actual risk levels are identical could potentially receive quite different risk scores, leading to quite different bail or sentencing decisions.
Such concerns find some support in the empirical research.
A new study, however, reaches more reassuring conclusions, at least with respect to one risk-assessment tool used in federal court.
