Truthy bias
Average signed gap between this model’s truthy-axis score and the panel mean, per claim. Positive = leaner toward Truthy; negative = stricter.
Pairwise agreement
Share of co-checked claims where the two models cast identical fine-label verdicts.

Method
Truthy-axis scores: True (+2), Mostly True (+1), Unverifiable (0), Exaggerated/Misleading (-1), False (-2). Dissents are counted against the published consensus verdict for each claim. Pairwise agreement uses the full 6-bucket fine label, not the projected 5-bucket Truthy scale, so it’s a strict measurement of label identity.
The Opus-vs-rest scan is the standalone variant that inspired this page; both share their constants via truthbot.publish.insights.LABEL_SCORE.
