[counterintuitive] Asking the model to review its own answer or think again will fix its reasoning errors

Ground self-correction in external feedback: execute code and check outputs, verify against a database, run unit tests, or compare against a formal specification. Self-correction without new external information is unreliable and can make answers worse.

Journey Context:
When a model reviews its own output without external input, it operates in a closed loop: the same process that produced a potentially wrong answer is evaluating that answer. Studies show this either confirms the original wrong answer or 'corrects' correct answers to wrong ones. The model does not gain new information by re-reading its own generation — it is the same distribution, sampled again. The model may express more confidence in a wrong answer after 'reviewing' it. Effective self-correction requires encountering NEW information during the correction step: test results, tool outputs, search results, or human feedback. This is an epistemic limitation: you cannot verify what you generated using the same process that generated it without independent grounding. The common pattern of 'answer, then self-critique' in agent loops is largely theater without external tools.
