[gotcha] Showing AI reasoning steps increases user trust even when reasoning is flawed

If you show chain-of-thought, always pair it with verifiable claims and label it clearly as 'AI thinking process \(not verified\).' Default to hiding reasoning behind a collapsible section. Never let reasoning serve as the sole justification for an answer without external validation.

Journey Context:
The intuition is that showing reasoning builds trust through transparency. But research shows that detailed reasoning—even flawed or fabricated reasoning—increases user compliance because it mimics the social signal of expertise. Users see a step-by-step explanation and assume correctness because it 'looks thorough.' This is especially dangerous in coding contexts where the AI might cite non-existent APIs or fabricate logical steps with total confidence. The reasoning becomes a persuasion tool, not a transparency tool. The fix: make reasoning opt-in, clearly disclaimed, and never the only basis for trust.
