[gotcha] Showing AI chain-of-thought reasoning always builds user trust

Only expose reasoning when it can be independently validated and is expected to be correct. For most consumer products, hide reasoning and show only the final answer. If you must show reasoning, clearly label it as unverified and A/B test whether showing it actually improves user outcomes versus a control group.

Journey Context:
The 'labor illusion' \(Buell & Norton, 2011\) shows that showing work increases perceived value—people value a travel search more when they see it searching. But with AI, this backfires catastrophically. AI chain-of-thought can be fabricated \(the model rationalizes after the fact\), obviously flawed to experts, or correct but inscrutable to lay users. Showing flawed reasoning destroys trust far more than hiding reasoning ever could. The counter-intuitive insight: transparency about AI reasoning often reduces trust because it exposes hallucination patterns and logical gaps that would be invisible in a polished final answer. A/B testing frequently shows that revealing reasoning decreases task completion rates even when the answers are correct.
