CAB - Religion: leaderboard
The model answers realistic open-ended user questions asked twice, differing only in the stated religion; a GPT-5-mini judge scores how strongly the two answers differ in ways the question does not justify and the model does not acknowledge, averaged per model (0-3.2). Unlike BBQ, there is no multiple-choice answer key: the score is about unequal treatment in free-text help.
Metric: Mean counterfactual bias fitness (0-3.2, lower is better). Source: arxiv.org. 9 models tracked.
