[gotcha] Streaming tokens cause users to form premature judgments on partial responses, especially for multi-part answers that pivot mid-stream

For multi-step reasoning or answers that may contradict their initial direction, consider: \(1\) using a non-streamed 'thinking' phase, then streaming only the final answer, \(2\) using progressive disclosure — show section headers first, then fill in content, \(3\) for answers where the conclusion matters more than the journey, buffer until the key claim is complete before showing. Never stream raw chain-of-thought to users who will act on partial output.

Journey Context:
Streaming is universally recommended for perceived latency — users see output immediately and feel the system is responsive. But streaming creates a subtle UX trap: as tokens appear, users start forming judgments and making decisions based on partial content. If the model starts with 'The answer is yes' and then pivots to '...however, upon further consideration, no,' the user has already processed 'yes' and may miss the pivot. This is especially dangerous in medical, legal, or financial contexts where premature action on partial information can cause harm. The counter-intuitive insight: faster perceived delivery can lead to worse comprehension and decision-making. The tradeoff is between perceived speed \(streaming\) and comprehension quality \(buffering\). For factual Q&A where the answer might be nuanced, a brief delay followed by a complete answer often produces better outcomes than instant streaming of a meandering response.
