[gotcha] Displaying AI chain-of-thought reasoning makes users trust wrong answers MORE, not less

If you show reasoning, pair it with explicit confidence indicators and independent verification cues. Never assume that showing reasoning helps users catch errors — it primarily functions as a trust signal, not an audit tool. For high-stakes outputs, show reasoning only alongside structured fact-checking UI, not as a standalone feature.

Journey Context:
The intuitive assumption is: showing AI reasoning lets users evaluate the logic and catch errors. Research consistently shows the opposite — the 'explanation effect.' When users see reasoning steps, they rate the same output as more trustworthy regardless of its correctness. The reasoning acts as a trust heuristic, not an audit mechanism. Users rarely actually read and evaluate the reasoning; they just note its presence. This is especially dangerous because reasoning can be fabricated — the model generates plausible-sounding steps that don't reflect its actual computation path. The tradeoff: hiding reasoning reduces transparency, but showing it creates false confidence. The right call depends on stakes — for low-stakes creative tasks, showing reasoning is fine. For factual, medical, or financial outputs, showing reasoning without verification support is actively harmful because it inflates trust without improving accuracy.
