Study: Reasoning models' self-correction does not guarantee correctness

An analysis of 15k reasoning traces reveals that reasoning models self-correct, test hypotheses, and acknowledge uncertainty more often than instruct models. However, these characteristics do not signal answer correctness, suggesting that relying on these behaviors to gauge output quality may be misleading.
