Today we bring you another look at key field partners who have helped make the Dane County PSA RCT one of the A2J Lab’s signature series. Part I covered the work of the County’s two Assessors, who perform the essential work of populating the PSA’s risk factors and generating its recommendations day in and day out.
Last week, we marked the launch of our PSA RCT in Dane County, Wisconsin. Starting today, I will be pulling back the field experiment curtain, as it were, and introducing some of the A2J Lab’s field partners. These Dane County employees have worked tirelessly for almost two years to make the PSA’s implementation and our concurrent evaluation possible.

The day has finally arrived!
At this afternoon’s initial appearance court in Dane County, WI, the A2J Lab begins its evaluation of the Public Safety Assessment (“PSA”). Criminal process in this jurisdiction now includes additional, scientifically based information in a randomly selected subset of cases to inform pre-disposition release decisions. The judicial official–known here as a Commissioner–receives risk scores and a recommendation for release through the PSA and its static criminal history inputs to consider in reaching those decisions.

How Should We Think about Racial Disparities?
In a previous post, I considered some of the less convincing critiques of pretrial and sentencing risk assessments that sound in the ecological fallacy. The fallacy argument mistakenly targets risk scores as applying only group inferences to individual case decision-making. The takeaway was straightforward. A comprehensive understanding of actuarial tools must include rigorous counterfactual thinking about a state of the world in which they aren’t available. In this follow-up, I discuss an even more serious claim: that actuarial tools might lead to unjustifiable racial disparities in criminal justice outcomes.
