[gotcha] AI responds to complex questions too quickly, causing users to distrust the output quality

For complex queries, intentionally add perceived thinking time via progress indicators, step-by-step reasoning display, or staged rendering; for simple queries, prioritize speed; match latency signals to query complexity

Journey Context:
There is a well-documented UX phenomenon where users conflate response time with effort and quality. A sub-second response to 'write a business plan' feels like the AI did not try, even if the output is excellent. Conversely, a 10-second response to 'what is 2\+2' feels broken. This is counter-intuitive for engineers who optimize for speed: faster is not always better for perceived quality. The fix is not to artificially slow everything down, but to match latency signals to task complexity. For complex tasks, streaming reasoning steps or showing a progress state increases perceived value and trust. For simple tasks, instant responses are expected and any delay feels like a bug.
