[gotcha] Exposing AI chain-of-thought reasoning reduces trust when intermediate steps contain errors

Default to hiding reasoning behind a 'Show reasoning' toggle. When shown, visually distinguish it from the final answer using muted styling, a collapsible section, or a different font. Never present reasoning steps with the same visual authority as the conclusion.

Journey Context:
The instinct is that transparency builds trust: show the work, let users verify. In practice, chain-of-thought reasoning frequently contains logical leaps, incorrect intermediate calculations, or circular logic that still arrives at a correct final answer. Users who spot a flawed step distrust the entire output — even when the conclusion is right. Research shows that transparent-but-flawed reasoning reduces trust more than no reasoning at all. The uncanny valley: reasoning that is 90% sound is worse than hidden reasoning because the 10% error is salient and alarming, triggering an 'if this step is wrong, what else is wrong?' cascade. The fix is counter-intuitive: less transparency at the surface, with opt-in depth, actually builds more trust than full exposure.
