Risk assessment algorithm used in bail hearings

“As part of a bold effort at bail reform,” writes Ephrat Livni, “the state of New Jersey replaced bail hearings with algorithmically informed risk assessments this year. Anyone’s eligible for release, no money down, if they meet certain criteria. To ensure unbiased, scientific decisions, judges use a machine-generated score. … The Public Safety Assessment (PSA) formula that New Jersey is now using for bail—along with about 20 other jurisdictions that employ it less extensively—aims to make risk calculations neutral, purely evidence-based, and premised on data. It compares risks and outcomes in a database of 1.5 million cases from 300 jurisdictions nationwide, producing a score of one to six for the defendant based on the information.”

“The automated recommendation”, Livni adds, “serves as a guide and doesn’t replace judicial discretion. Still, the program raises questions about the claimed neutrality of machine reasoning, and the wisdom of reliance on mechanical judgment.” For more, see In the US, some criminal court judges now use algorithms to guide decisions on bail. — Joe
