[gotcha] Displaying AI chain-of-thought reasoning reduces user trust instead of increasing it

Hide AI reasoning by default in consumer products. Expose it only on demand via a 'Show thinking' toggle, and only when reasoning quality is high. Never surface raw chain-of-thought that contains visible errors, circular logic, or unexplained leaps.

Journey Context:
The intuition is compelling: showing AI reasoning increases transparency, so users can verify the logic and trust the answer more. In practice, the opposite occurs. Chain-of-thought reasoning often contains logical leaps, redundant steps, or outright errors that the final answer does not reflect. When users spot these errors in the reasoning, they lose trust in the final answer — even when the answer is correct. This is the 'uncanny valley of reasoning': reasoning that is almost right but visibly flawed is worse than no reasoning at all. Users either spot an error and distrust the whole output, or cannot follow the reasoning and feel the AI is opaque in a different way. The fix: treat reasoning as a debugging and development tool, not a trust-building UX feature. Show it only when users explicitly ask and when you can guarantee quality.
