[gotcha] Showing AI reasoning steps increases user trust in wrong answers

If displaying chain-of-thought reasoning, pair it with explicit uncertainty indicators and verification cues; consider hiding reasoning behind an expandable disclosure by default rather than showing it prominently

Journey Context:
Counter-intuitively, exposing AI reasoning makes users MORE likely to accept wrong answers. The step-by-step structure creates an illusion of rigor: even flawed logic feels authoritative when laid out as reasoning. This is the explanation effect, documented in HCI research: explanations increase user agreement with AI recommendations regardless of whether the AI is correct. In product UX, prominently displaying reasoning can actively harm user decision-making by increasing overtrust. The safe default is to hide reasoning behind a disclosure pattern \('Show reasoning'\) and, when shown, pair it with confidence calibration signals that remind users reasoning does not guarantee correctness.
