[gotcha] Displaying AI chain-of-thought reasoning increases user trust regardless of reasoning quality

Default to hiding reasoning behind a collapsible 'Show reasoning' toggle. If reasoning must be shown, pair it with a disclaimer that reasoning is generated and not verified. Never present reasoning as proof of correctness.

Journey Context:
Research demonstrates the 'explanation effect': users shown AI reasoning trust the output more, regardless of the reasoning's actual quality. This is counter-intuitive because transparency is generally good UX practice, but here it creates false validation. LLMs excel at generating plausible-sounding but flawed reasoning, which is more dangerous than no reasoning at all because it gives users a false sense of understanding why the answer is correct. Making reasoning opt-in means users who actively choose to view it are in a more critical mindset than those who have it pushed on them. This preserves transparency without creating unwarranted trust.
