[counterintuitive] Why does the model state wrong answers with the same confidence and authority as correct ones?

Never use the model's expressed confidence or assertiveness as a signal of correctness. Implement external verification \(unit tests, type checking, documentation lookup, linters\) for all factual claims and code outputs. Treat every model assertion as unverified until externally validated, regardless of how authoritative it sounds.

Journey Context:
Developers intuitively trust confident statements more than hedged ones, and expect that a model's confidence correlates with accuracy. Research shows LLM confidence is poorly calibrated for specific, verifiable claims — the model expresses high confidence for both correct and incorrect outputs. This is compounded by RLHF training, which specifically trains away hedging language \('I think', 'possibly'\) in favor of direct, helpful-sounding responses. The model has learned that confident answers score higher in human preference evaluations, regardless of accuracy. Additionally, the model has no reliable internal uncertainty signal that maps to output confidence on a per-query basis — it generates tokens probabilistically but lacks metacognitive access to its own reliability. This means a model will state an incorrect API signature with exactly the same authoritative tone as a correct one, making it impossible to distinguish right from wrong based on the model's presentation alone. The only reliable signal is external verification.
