[gotcha] Displaying chain-of-thought reasoning increases trust even when reasoning is confabulated — users become less accurate at detecting errors

Only expose reasoning when it is independently verifiable \(cites specific sources, shows explicit calculations, references provided context\). Hide purely narrative reasoning. If showing reasoning, label it as 'model's reasoning process' not 'analysis' or 'evaluation.' Default to hidden reasoning with progressive disclosure — let users opt in to seeing it.

Journey Context:
The strong intuition: if users can see the AI 'think,' they can evaluate its logic and catch errors. Research shows the opposite — chain-of-thought explanations increase trust regardless of correctness. Users read plausible-sounding reasoning, find it convincing, and lower their guard. The reasoning becomes trust theater: it persuades rather than informs. This is especially dangerous because LLM reasoning is often confabulated — the model generates the answer first, then constructs plausible justification, rather than deriving the answer from the reasoning. Turpin et al. \(2023\) demonstrated that models' stated reasoning often doesn't match their actual computation. The fix is to treat reasoning display as a liability, not a feature. Show it only when auditable \(tied to specific evidence\), label it clearly as the model's process, and default to hidden. Progressive disclosure lets power users inspect reasoning without exposing casual users to persuasive but unreliable justifications.
