The Calibration Floor: Format Repair Can Masquerade as Self-Correction at Small-to-Mid Scale
Mingguang Chen, Bo Qu, Licheng Wang
Accuracy changes after language-model self-revision are usually interpreted as changes in reasoning. We show this can fail at the answer-extraction boundary, and test the failure c…
