[gotcha] Showing AI reasoning steps in the UI decreases user trust when reasoning contains errors, even if the final answer is correct

Default to hiding chain-of-thought and reasoning steps behind an expandable disclosure widget. Only show reasoning by default in high-stakes domains where auditability is required \(medical, legal, financial\). When you do show reasoning, clearly label it as 'model reasoning process—may contain inaccuracies' and separate it visually from the final answer.

Journey Context:
The intuition is that showing reasoning increases transparency and trust. In practice it often does the opposite. Chain-of-thought reasoning frequently contains factual errors, logical leaps, or hallucinated premises that the model nonetheless arrives at a correct conclusion despite. When users spot an error in the reasoning, they lose confidence in the entire output—even if the final answer is independently correct. This is the 'reasoning trust inversion': more transparency leads to less trust when the reasoning is imperfect. Anthropic's extended thinking feature addresses this by separating the thinking process from the response and making it optional to view. The tradeoff is between auditability and user confidence. For most consumer products, hide reasoning by default. For professional tools where correctness must be verifiable, show it with appropriate framing.
