[gotcha] Displaying chain-of-thought reasoning increases trust in wrong answers

If you show AI reasoning, pair it with verification affordances: inline source citations that link to checkable references, confidence indicators on individual reasoning steps, and explicit disclaimers that reasoning is generated not audited. If you cannot enable verification, prefer hiding reasoning and showing only the final answer with calibrated confidence signals.

Journey Context:
Showing chain-of-thought reasoning seems like a transparency win — users can see how the AI arrived at its answer. But two failure modes dominate: \(1\) Users see reasoning output and assume it's been audited or verified, creating unearned trust. The reasoning looks logical but may contain fabricated premises or hallucinated intermediate steps — a phenomenon where confident-sounding logic built on false premises is more misleading than a simple wrong answer. \(2\) Users skip the reasoning entirely because it's verbose, creating an illusion of transparency without actual scrutiny. Research shows that explanations increase trust regardless of accuracy — a well-reasoned wrong answer is trusted more than a correct answer with no reasoning shown. The uncanny valley here: reasoning that looks human-like in structure but was generated by a pattern-matching system, not a truth-seeking process. The fix is to either hide reasoning or make it genuinely verifiable with source citations and claim-level confidence.
