[gotcha] Displaying AI chain-of-thought reasoning reduces user trust even when the final answer is correct

Default to hiding AI reasoning. Expose it only via an explicit user action \(e.g., 'Show reasoning' toggle or accordion\). When displayed, format it as visually distinct from the final answer—different background color, collapsed by default, clearly labeled as 'AI reasoning process' rather than 'explanation.' Never interleave reasoning tokens with answer tokens in the same visual stream.

Journey Context:
The intuition is that showing reasoning increases transparency and therefore trust. In practice, AI chain-of-thought often looks alien to human reasoning: it may be circular, repetitive, make strange logical leaps, or include hedging that reads as uncertainty. Users evaluate the reasoning using human norms and find it unsettling—the uncanny valley of AI cognition. Even when the final answer is correct, seeing the 'weird' reasoning path makes users doubt it. This mirrors established findings in explainable AI research: explanations that do not match the user's mental model decrease trust rather than increase it. Anthropic's implementation of extended thinking in Claude reflects this pattern—thinking tokens are collapsed by default, visually separated from the response, and opt-in to view. The counter-intuitive takeaway: transparency can backfire when the revealed process is comprehensible enough to evaluate but alien enough to disturb.
