The deployment of algorithms and artificial intelligence can have unintended consequences. Back in April, the Associated Press released an investigation into an algorithm used by one Pennsylvania county to help decide which families to investigate for child neglect and abuse. Researchers found that, if not for the intervention of social workers, the algorithm would have exacerbated racial disparities. Since that report, Oregon stopped using a similar tool. Sally Ho, an investigative correspondent with the Associated Press, co-authored the report. Marketplace’s Kimberly Adams spoke with Ho about how the algorithm in Pennsylvania worked.
