Walks through the ProPublica COMPAS dataset (~7,214 rows), reproduces the recidivism score with a simple logistic regression (~76% accuracy) and shows Black defendants have 2x higher false positives while White defendants have ~2x higher false negatives; demonstrates that dropping race barely changes results, balancing the target ratio reduces disparity but shrinks data and hurts accuracy, and contrasts real-world failures like Google’s gorilla label and a 34.4% error gap in facial APIs; recommends pre-/in-/post-processing mitigation and governance.
