[gotcha] Showing AI chain-of-thought reasoning increases trust in wrong answers and decreases trust in correct ones

Default to hiding reasoning from end users. Only surface chain-of-thought when: \(a\) the user explicitly requests it, \(b\) the domain requires auditability \(medical, legal, financial compliance\), or \(c\) you need the user to catch reasoning errors. When shown, pair reasoning with explicit confidence caveats and a distinct visual treatment that separates thinking from answer.

Journey Context:
The intuition is that showing AI reasoning helps users verify answers and builds appropriate trust. In practice it creates a transparency paradox: \(1\) Plausible-sounding reasoning creates false confidence in wrong conclusions — users anchor on the reasoning narrative and stop critically evaluating the answer. \(2\) When reasoning is visibly flawed or circular, users lose trust even in correct conclusions. \(3\) Non-expert users conflate reasoning length with answer quality. Research by Buccinca et al. \(2021\) demonstrated that explanations increase user reliance on AI regardless of AI accuracy — this is actively harmful when the AI is wrong. The right call is selective transparency: hide reasoning by default, show it only when the user's job is to verify the process \(not just consume the output\), and always visually distinguish reasoning from the final answer.
