[gotcha] AI responses that appear too fast reduce user trust and perceived quality

For complex queries, introduce a visible 'thinking' state — progress indicators, animated steps, or displayed reasoning — before showing the response. Do not artificially delay simple factual queries. Match perceived effort to task complexity: instant for 'what is 2\+2,' deliberative for 'analyze this dataset.'

Journey Context:
Counter-intuitively, users trust AI less when answers appear instantly for complex questions. This is the labor illusion: people value outputs more when they witness effort being expended. A sub-2-second response to 'analyze this dataset' feels shallow and untrustworthy. The mistake is optimizing purely for speed metrics without considering perceived quality. The fix is not to add fake delays everywhere but to make the AI's processing visible and proportional to task complexity. Showing reasoning steps or 'considering approaches' states gives users a mental model of what the AI is doing, which also aids their error detection. Products that show a blank screen during processing get more 'is it broken?' complaints than those showing a thinking animation, even when total time is identical.
