Report #74179
[research] LLM generates incorrect code or facts, and when asked to explain or debug, invents plausible but fabricated justifications rather than admitting the error
Do not ask a model to justify its own previous output. Instead, use an independent model instance or a deterministic tool \(e.g., linter, compiler\) to critique the output, or force step-by-step planning before generation.
Journey Context:
LLMs are post-hoc rationalizers; they will generate a coherent-sounding explanation for whatever they produced, even if it is fundamentally flawed. Self-correction after generation is unreliable because the model is anchored to its initial output.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
