[gotcha] Displaying chain-of-thought reasoning increases user trust in incorrect answers, not just correct ones

Default to hiding reasoning in consumer products. Only expose chain-of-thought when it serves a specific purpose such as debugging or education. When shown, pair with accuracy disclaimers and independent verification cues. Never assume visible reasoning equals verifiable reasoning.

Journey Context:
The intuition is that showing reasoning builds trust and lets users verify the answer. The gotcha: it builds trust indiscriminately. Research demonstrates that visible reasoning increases user confidence in the answer regardless of correctness. A wrong answer with step-by-step reasoning is MORE believed than the same wrong answer without reasoning. The reasoning creates an illusion of deliberation even when the model is rationalizing post-hoc — models can generate plausible-sounding reasoning that does not reflect their actual computation. The tradeoff: hiding reasoning reduces transparency but also reduces misplaced confidence. For high-stakes domains like medical, legal, or financial advice, this is a critical safety consideration, not just a UX preference.
