[gotcha] Why do users distrust AI responses that appear too quickly even though fast latency is technically better

For high-stakes or creative tasks, introduce a minimum perceived processing time of 500ms-1.5s before displaying results. Show task-specific progress indicators \('Analyzing your data...', 'Cross-referencing sources...', 'Checking against guidelines...'\) during this window. For simple factual lookup tasks, respond immediately — the mismatch only matters when task complexity implies more work than the response time suggests.

Journey Context:
The instinct is to minimize latency — faster is better, right? Not always. Users have an implicit mental model of how long complex tasks should take. When an AI produces a detailed analysis in 200ms, users assume it couldn't have done thorough work. This is the 'labor illusion': people value results more when they witness effort, even artificial effort. The common mistake is optimizing purely for speed without considering perceived effort. The opposite mistake — always adding artificial delay — wastes time for simple tasks and feels patronizing. The right call is task-dependent: match perceived processing time to task complexity. Use the delay productively by showing meaningful progress steps that educate the user about what the AI is doing, which also sets expectations for the kind of answer they'll receive.
