[gotcha] Faster AI responses feel less trustworthy in high-stakes domains

For high-stakes contexts \(medical, legal, financial, security\), intentionally add a visible processing phase: show 'Analyzing...', 'Reviewing sources...', or step-by-step progress indicators. Do not optimize for time-to-first-token alone. Match perceived deliberation to the gravity of the task.

Journey Context:
Engineering instinct: minimize latency, maximize speed. But behavioral research shows the 'labor illusion' — users value outputs more when they perceive effort behind them. An AI that returns a medical interpretation in 200ms feels like it is guessing. The same output after 3 seconds of visible 'analyzing' feels considered. This is counter-intuitive for engineers trained to optimize for speed. The key insight: perceived latency and actual latency are different UX variables. You can have fast computation with slow, deliberate-feeling presentation. The trick is making the waiting feel purposeful \(showing steps\) rather than like a loading spinner \(which feels like the system is struggling\). Buell and Norton's research at Harvard demonstrated this effect quantitatively: operational transparency increases perceived value even when it adds wait time.
