Adding order metadata makes VLM error detection collapse, new benchmark shows

The post highlights a VLM failure mode: when order metadata was added, error detection collapsed because the model anchored on the expected image contents instead of checking the pixels.
The attached chart contrasts the expected calibrated update with the observed outcome, where the prior wins, evidence is ignored, and missed errors increase. The author says this matches a prior-dominant bias similar to results reported by Deng et al. (CVPR 2025).
