[gotcha] Showing AI chain-of-thought reasoning decreases user trust instead of increasing it

Only expose reasoning when it directly helps the user verify the output \(math steps, logical deductions, source citations\). Hide reasoning for creative or conversational tasks. When showing reasoning, format it as structured steps or evidence, not natural language 'thinking.' Never display reasoning that expresses uncertainty about the final answer—uncertainty in reasoning undermines the output even when the output is correct.

Journey Context:
The intuition is that showing AI reasoning builds trust through transparency. But this has an uncanny valley with two failure modes. Reasoning that's too human-like \('Let me think about this... I should consider...'\) triggers anthropomorphism discomfort and feels manipulative—users sense they're reading simulated inner monologue, not actual transparency. Reasoning that's too mechanical is just noise. The real gotcha: showing reasoning that expresses uncertainty \('I'm not entirely sure, but...'\) DECREASES trust even though it's epistemically honest, because users expect tools to be confident. Seeing the AI 'doubt itself' makes users doubt the output, even when the output is correct. The fix is to treat reasoning as verification material, not personality. Structured steps that help the user check the work build trust; simulated thinking destroys it.
