[counterintuitive] Ask the LLM to verify or double-check its own reasoning to catch mistakes
Use external verification tools—code execution, unit tests, formal checkers, or human review—to validate model outputs. Self-correction without external feedback is unreliable and should not be trusted as a quality gate.
Journey Context:
It is deeply intuitive that a model smart enough to generate an answer should be smart enough to verify it. But research demonstrates that LLMs cannot effectively self-correct reasoning without external feedback. When asked to 'check your work' or 'verify your answer,' models tend to either re-affirm their initial output or make different errors—not genuinely audit their reasoning. The model's own output biases its verification step. This is especially pernicious because self-correction appears to work on easy problems \(where the model would have been right anyway\), creating a false sense of reliability. The mental model: self-correction is not a substitute for external validation; it is the model reading its own handwriting.
