[gotcha] Sub-second AI responses feel less thoughtful than the same answer delivered after a moderate pause

Calibrate perceived latency to task stakes: use around 9 seconds for advice and creation tasks, show meaningful progress such as 'checking sources,' and avoid instant replies when deliberation is expected.

Journey Context:
A CHI 2026 study found that 2-second responses were rated as less thoughtful and less useful than 9–20-second responses, even when the underlying content was identical. Users anthropomorphize latency as 'thinking.' But the effect is task-dependent: longer waits backfire for advice tasks while creation tasks tolerate more delay because quality-contingent value is higher. The engineering instinct is to minimize latency; the product instinct should be to choreograph it with honest progress indicators that match user expectations.
