[gotcha] Streaming AI responses create anchoring bias that prevents users from catching errors mid-stream

For accuracy-critical tasks, either buffer the full response before display, render streaming text in a visually distinct 'draft' state requiring explicit acceptance, or add a mandatory review step after streaming completes before the output is committed or acted upon.

Journey Context:
When text streams in token by token, users begin reading and processing immediately. This creates an anchoring effect: by the time the full response is visible, the user has already started accepting early tokens as truth. If the response starts correct but hallucinates in the middle or end, users are less likely to catch it than if they reviewed the complete response at once. Streaming makes everything feel more considered and deliberate, but it actually reduces critical evaluation—the progressive reveal creates a false sense of linearity and correctness. The counter-intuitive insight is that streaming—universally recommended for perceived latency—can be actively harmful for accuracy-critical tasks. The fix is not to abandon streaming but to add friction at the right points: stream for the experience, but gate action on the output behind an explicit review step.
