[gotcha] Streaming AI responses cause users to commit to partial answers before the full response arrives

Buffer streaming output until complete semantic units \(full sentences or paragraphs\) before rendering. Keep a persistent visual 'generating' indicator active until the stream fully completes. Avoid rendering fragmentary clauses that could be misinterpreted as standalone assertions.

Journey Context:
Streaming reduces perceived latency but introduces a subtle cognitive trap: users begin reading and forming judgments as tokens arrive. If an AI starts with 'Yes, you should…' and then pivots to '…however, there are significant risks,' skimmers may only process the initial affirmative. Users treat streaming text as a social cue — like someone speaking to them — creating implicit trust in early tokens. The counter-intuitive insight is that streaming, which exists to improve UX, can actually reduce comprehension and increase the risk of users acting on reversed or incomplete conclusions. The tradeoff is between perceived speed and comprehension fidelity. Buffering by sentence rather than by token is the sweet spot: fast enough to feel responsive, coherent enough to prevent misreading.
