[gotcha] AI response returned too quickly for a complex task, users assume it's wrong or low-effort

For tasks where a human expert would need significant time \(detailed analysis, code review, creative writing\), add a visible 'thinking' or 'analyzing' phase before displaying the response. Do not artificially delay simple factual queries — only add perceived-effort signals for complex tasks where instant response feels careless.

Journey Context:
Conventional UX wisdom says faster is always better. For AI, this breaks down. When a user asks for a detailed financial analysis and gets a 3-paragraph response in 0.3 seconds, they assume the AI didn't actually analyze anything — even if the answer is excellent. This is counter-intuitive because every performance optimization says 'reduce latency.' The key insight: users have a mental model of how long thinking takes, and AI violates it. Research on response time perception shows that sub-second responses feel instantaneous but also thoughtless for complex tasks. The 1-10 second range feels like 'working on it.' The fix isn't to slow everything down — simple factual questions should still be fast. But for complex tasks, a 'thinking' indicator serves as a trust signal, not just a loading state. It tells the user 'the AI is taking this seriously,' which paradoxically makes the eventual answer more credible.
