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

Default to hiding AI reasoning. Show it only on explicit user request via a 'Show reasoning' toggle. When reasoning is displayed, frame it as 'supporting detail' not 'proof.' If the reasoning contains errors but the conclusion is sound, this is expected — do not try to sanitize it, but do not surface it by default.

Journey Context:
The educational instinct is 'show your work equals more trustworthy.' But AI reasoning is post-hoc: the model generates reasoning that supports its answer, not reasoning that produced it. Users who spot a logical flaw in the reasoning discount the entire output, even when the conclusion is independently correct. This is the opposite of the human-expert effect where showing work increases trust. The uncanny valley of AI reasoning: reasoning that is almost-but-not-quite human-like is worse than no reasoning at all. OpenAI's o1 hides reasoning tokens by default; Anthropic's extended thinking makes thinking blocks optional to display. Both made this design choice for good reason.
