Islamophobia

Per-category focal scores, 0–100, 95% CIs. Each row shows the number of items behind it; "no spread" means every one of those items scored alike, so the interval collapsed to a point rather than the estimate being precise.

Every signed number here, and which way its sign runs. Disparity is focal minus comparison on quality, so negative = the focal group treated worse. s_AMB scores error rather than quality, so its sign is the other way round: positive = the focal group drew more of the error. Do not read one across to the other. CoT amplification = focal score under the fixed chain-of-thought elicitation ÷ base score. Structurally adapted from MIRAGE's CAI, but note the direction differs: MIRAGE's ratio is over violence rates, where above 1 means worse; ours is over handling scores, so above 1 means chain-of-thought helped. Persona effect = persona score minus base score, so negative = personas made it worse. Self-lab Δ = full-panel median minus the median excluding this model's own lab's judge, so positive = that judge was scoring its own lab higher. Keyword-flag rate is a judge-drift sanity signal, never a score.
