[gotcha] Showing AI chain-of-thought reasoning increases user trust in the output even when the reasoning is flawed or fabricated

Only expose AI reasoning when the reasoning can be independently verified by the user, such as mathematical steps, code logic, or cited sources. For subjective or factual claims, hide reasoning or present it as supporting detail rather than proof. Always pair visible reasoning with explicit uncertainty markers when the model expresses low confidence. Never present reasoning as a guarantee of correctness.

Journey Context:
Transparency seems like an unalloyed good: show the user how the AI reached its conclusion so they can verify it. But in practice, seeing step-by-step reasoning creates an illusion of deliberation where users assume that because the AI went through steps, the conclusion must be sound. Research on chain-of-thought faithfulness shows models can fabricate plausible-sounding justification for answers they arrived at through pattern matching, not genuine reasoning. The reasoning looks logical but does not reflect the actual computation. The fix is not to always hide reasoning, but to be selective: show it when it adds verifiable value and always pair it with appropriate uncertainty signals.
