[gotcha] Instant AI responses make users doubt output quality

For complex or high-stakes queries, introduce a brief visible thinking or analyzing phase of 1-3 seconds before streaming begins. For simple factual queries, respond immediately. Match perceived effort to perceived task complexity. Streaming itself partially addresses this but a pre-stream delay for complex tasks significantly increases trust.

Journey Context:
This inverts normal web UX where faster is always better. Research on the labor illusion demonstrates that people value outputs more when they can see work being done, even if the work is theatrical. An AI that instantly returns a nuanced analysis feels like it did not think hard enough — users assume it is generic or shallow. Conversely, a brief delay with a processing indicator makes the same output feel more considered and trustworthy. This is counter-intuitive for engineers trained to minimize latency at all costs. The key is calibration: simple lookups should be fast, matching user expectations for search-like interactions, while complex reasoning should show visible effort. Streaming partially solves this by showing tokens arriving, but the initial latency before the first token is where the labor illusion matters most.
