Survey of 300+ papers says better reasoning does not make LLMs more self-aware

A new survey on metacognition in LLMs argues that stronger reasoning does not automatically make models better at knowing when they are wrong.

Across 300+ papers, the authors find that models can reason better while still failing at self-monitoring.
Even DeepSeek-R1 struggles with basic metacognitive tasks such as estimating the length of its own reasoning trace or predicting task success.
The paper’s central claim: reasoning depth and self-knowledge depth are not the same thing, and more reasoning can even correlate with worse metacognitive sensitivity.
It surveys methods, benchmarks, applications, open questions, and a GitHub reading list for the field.
