Report #99068

[counterintuitive] Model sounds confident but is wrong and cannot reliably say it does not know

Do not interpret fluency or confidence as accuracy. Use calibrated confidence scores, retrieval-augmented generation, refusal training, and always cross-check high-stakes outputs.

Journey Context:
Fluency and confidence correlate with human expertise, so developers trust them. LLMs generate the most likely next token given training data, not a calibrated probability of truth. They can be highly confident about false claims. Better prompts cannot create true metacognition; the fix is external grounding and explicit uncertainty handling.
