DEPARTMENT OF PRE-CRIME: Not magic: Opaque AI tool may flag parents with disabilities. “Over the past six years, Allegheny County has served as a real-world laboratory for testing AI-driven child welfare tools that crunch reams of data about local families to try to predict which children are likely to face danger in their homes. Today, child welfare agencies in at least 26 states and Washington, D.C., have considered using algorithmic tools, and jurisdictions in at least 11 have deployed them, according to the American Civil Liberties Union. The Hackneys’ story — based on interviews, internal emails and legal documents — illustrates the opacity surrounding these algorithms. Even as they fight to regain custody of their daughter, they can’t question the “risk score” Allegheny County’s tool may have assigned to her case because officials won’t disclose it to them. And neither the county nor the people who built the tool have explained which variables may have been used to measure the Hackneys’ abilities as parents.”
