[counterintuitive] LLMs can reliably judge whether their own output is correct, safe, or faithful

Use independent verification systems, human reviewers, or automated tests. Never use the same model instance to grade its own high-stakes outputs without external ground truth or cross-checks.

Journey Context:
Self-evaluation is popular \('critique your own answer', 'rate your confidence', 'judge whether this is safe'\). It fails because the model grading its own output is sampling from the same distribution that produced the output; it shares the same blind spots and confabulations. Studies show LLM self-consistency and self-verification improve on easy cases but can reinforce errors on hard ones. The architectural issue is that there is no separate, reliable verifier module. For safety, correctness, and faithfulness, the answer must come from outside the generative model: tests, citations, separate classifiers, or human oversight.
