[gotcha] Confident AI hallucinations feel more trustworthy than hedged correct answers — fluency becomes false accuracy signal

Decouple presentation quality from truth signals. Always display citations or source references when available. Use consistent formatting for all responses regardless of model confidence. Add provenance indicators independent of response fluency \(e.g., 'based on provided documents' vs 'based on training data'\). Never let response polish serve as an implicit accuracy signal.

Journey Context:
This is the core UX trap of LLMs: a response that says 'The answer is X, because...' with perfect grammar and confident structure feels more reliable than one that says 'I'm not entirely certain, but it might be Y...' — even when Y is correct and X is a hallucination. Users conflate fluency with accuracy because in human communication, confident speakers are usually knowledgeable. This heuristic inverts for AI. The fix isn't to make responses less fluent \(that degrades all interactions\) but to add independent trust signals that don't correlate with formatting quality. Citations, source attribution, and confidence indicators give users a second channel to evaluate accuracy. Without these, users have only fluency as a signal — and it's the wrong one.
