Interaction & Behavior
Doherty Threshold
Productivity peaks when system response stays under ~400ms.
Takeaways
- 1
Sub-400ms feedback keeps users in flow.
- 2
Use skeleton states that mirror final content shape.
- 3
Avoid blocking the UI while background work completes.
Origins
The Doherty Threshold emerged from research on human–computer pacing: when systems respond quickly enough, interaction feels like a conversation rather than a wait. Delays beyond a few hundred milliseconds break rhythm and increase perceived effort.
Performance is therefore a core UX responsibility, not only an engineering metric.
Design Applications
- Optimistic UI can make actions feel immediate.
- Prefer skeleton loaders over generic spinners.
- Animate transitions around 200–300ms for responsiveness.
