Risk assessments—computer programs that predict the likelihood of someone committing a crime—are increasingly common in courtrooms, yet these “future-crime formulas” are marked by troubling racial prejudices that can influence everything from bond amounts to sentencing to prison time. Julia Angwin of ProPublica examines the hidden biases of these allegedly objective algorithms and their powerful effect on the American criminal justice system. Moderated by USC journalism professor Laura Castãneda.
