[gotcha] Streaming AI responses create a fluency effect that makes users less critical of incorrect output

For factual or high-stakes outputs, add post-stream verification signals: a brief 'Verified against sources' indicator, confidence scores, citation links, or a 'Check this answer' prompt. Never let the visual momentum of streaming substitute for accuracy signals. Consider a subtle UI distinction between 'AI-generated' and 'verified' content.

Journey Context:
The 'processing fluency' effect \(Alter & Oppenheimer, 2009\) is a well-documented cognitive bias: information that is easier to process is judged as more truthful and more likeable. Streaming makes AI output feel fluent — tokens arrive smoothly, the response 'flows' — and this fluency reduces critical scrutiny. Users are more likely to accept a streamed hallucination than the same hallucination delivered all-at-once. This is counter-intuitive because streaming was designed for UX, not persuasion. The fix isn't to stop streaming \(users prefer it\) but to add accuracy signals after streaming completes, breaking the fluency illusion at the moment of evaluation.
