[counterintuitive] Asking the model to review and fix its own output reliably catches its mistakes

Always ground correction loops in external feedback: test execution results, compiler errors, linter output, or formal verification. Never rely on the model's self-assessment as the sole error signal for reasoning tasks.

Journey Context:
The intuitive mental model is that a smart model can 'step back' and review its output the way a human proofreads. But the model uses the same internal representations to judge its output as it used to generate it. Without an external ground truth signal, self-correction in reasoning tasks has been empirically shown to either maintain or degrade accuracy — the model corrects right answers to wrong ones at similar rates to catching actual errors. The model's confidence in its self-assessment is uncalibrated because the assessment and the generation share the same failure modes. This doesn't mean the model can never improve output on re-prompting \(it can catch formatting issues or obvious contradictions\), but for reasoning errors, the same flawed reasoning that produced the error will approve it on review. True error correction requires an independent oracle: code execution, test suites, or human feedback.
