[gotcha] AI responses that return too quickly decrease user trust and perceived quality

Implement a minimum display latency for AI responses: show a 'thinking' or 'analyzing' state for at least 1-2 seconds before revealing the response; for complex queries, consider progressive disclosure \(show reasoning steps before the final answer\)

Journey Context:
In traditional web UX, faster is always better — latency is the enemy. This intuition breaks down with AI. When an AI answers a complex question in under 500ms, users apply a 'machine heuristic': they assume the response is canned, trivial, or low-effort. Research shows that perceived helpfulness increases when there's a visible processing delay, because users associate time with effort and deliberation. Teams that optimize relentlessly for latency are confused when user satisfaction scores drop. The counter-intuitive lesson: some latency is a feature, not a bug. The tradeoff: artificial delay feels dishonest if discovered, and users who understand AI may find it patronizing. The right call is to show genuine processing states \(not fake spinners\) and let the natural model latency do the work — only add delay if responses are genuinely sub-second for complex tasks.
