[gotcha] AI responses arriving in under 500ms feel canned, cached, or low-quality to users

For complex or high-value queries, enforce a minimum perceived processing time of 800ms-1.5s before revealing results. Show a progressive thinking/processing animation during this window.

Journey Context:
Engineering teams invest heavily in reducing latency, but sub-second responses to complex questions trigger a suspicion heuristic: users assume the output is pre-computed, templated, or generic. This is the opposite of the standard web performance axiom where faster is always better. Research shows that for tasks perceived as requiring thought, a brief processing delay actually increases perceived value and trust. The key insight is that perceived intelligence requires perceived effort. The delay must feel like computation, not artificial — use a progressive thinking indicator with visible steps, not a static spinner. The gotcha is that your latency dashboards look great while your user trust metrics silently decline.
