[gotcha] Showing AI chain-of-thought reasoning to build trust actually reduces it

Hide intermediate reasoning by default. Only expose it on demand via a 'Show reasoning' toggle. When you do show it, frame it as 'approach' not 'proof' — make clear the reasoning is a narrative, not a verifiable audit trail.

Journey Context:
The intuition is strong: show the AI's work so users can verify it. In practice, this backfires because \(1\) language models often produce unfaithful chain-of-thought — the reasoning doesn't actually reflect how the model arrived at its answer, known as the motivated reasoning problem, \(2\) users who spot a flawed intermediate step will reject the entire output even if the final answer is correct, and \(3\) verbose reasoning increases cognitive load without improving decision quality. Research shows that CoT explanations can increase over-reliance on wrong answers when the reasoning sounds plausible. The right call is to default to clean answers and make reasoning opt-in, treating it as a debugging tool for power users, not a trust-building feature for everyone.
