A new paper introduces a framework for evaluating fairness in toxicity detection models, considering ranking, calibration, and abstention. The research found that standard training methods like Empirical Risk Minimization (ERM) can appear well-calibrated overall but exhibit significant calibration disparities across different identity subgroups. Interventions like instance-level reweighting improve ranking but worsen calibration fairness, while Group Distributional Robustness Optimization (Group DRO) eliminates calibration disparity by becoming uniformly miscalibrated globally. The study also highlights that post-hoc methods like temperature scaling and confidence-based abstention inherit training failures and can themselves be unfair, disproportionately benefiting certain content types over others.
