[gotcha] Displaying AI chain-of-thought reasoning creates false trust when the reasoning itself contains hallucinations

If you show reasoning, visually distinguish it from the final answer using collapsible sections, different styling, and explicit labels like 'AI reasoning process — may contain errors'. Never present reasoning as verified fact. For high-stakes domains, hide reasoning and show verification sources instead.

Journey Context:
The instinct is that showing reasoning builds trust and lets users verify the AI's logic. But research shows that displaying step-by-step reasoning creates an illusion of correctness — users see the structured format and assume rigor, even when individual steps are fabricated. This is the process fairness bias: people trust outputs more when they can see a process, regardless of process quality. The common mistake is treating reasoning display as purely beneficial transparency. The right call is to show reasoning only when it genuinely aids verification \(math, logic puzzles\) and to clearly label it as fallible. For creative or conversational tasks, hiding reasoning is better because it adds noise without verification value.
