[gotcha] Showing AI chain-of-thought reasoning to build trust backfires when reasoning contains visible errors, reducing trust more than hiding reasoning entirely

Default to hiding raw chain-of-thought from end users. If transparency is required, show a cleaned-up reasoning summary rather than raw model output. Test with users: if showing reasoning doesn't measurably improve decision quality, omit it — partial transparency is worse than none.

Journey Context:
A common intuition is that showing AI reasoning \(chain-of-thought\) increases trust through transparency. But XAI research reveals an 'explainability backfire' effect: when an AI explanation contains an error the user can spot, trust drops more than if no explanation was provided. The user reasons: 'If the reasoning is wrong here, where else is it wrong?' Raw chain-of-thought is particularly risky because it often contains hedging, backtracking, and intermediate errors that the model self-corrects — but users don't interpret these as self-correction; they see mistakes. The counter-intuitive takeaway: partial transparency is worse than no transparency. Either show a polished, verified reasoning summary or show nothing. This is especially important for consumer products where users aren't AI researchers and don't understand that chain-of-thought is a generated artifact, not a genuine reasoning trace. Teams building with reasoning models that expose thinking traces should be especially cautious about surfacing these raw to end users.
