Triage interruptions before acting on them
When something interrupts you, categorize it as urgent-now or capture-for-later before deciding whether to switch.
Why it works
Most interruptions generate an automatic orienting response — the brain has a hard-wired tendency to redirect attention toward novel stimuli, which evolved for threat detection. In a knowledge-work environment, this response fires for trivial notifications as readily as for genuine priorities. Inserting a deliberate triage step introduces executive control between the interrupt signal and the switch decision, converting an automatic reaction into a conscious choice.
How to do it
- When interrupted (notification, knock, email), pause before acting and ask: "If I don’t respond in the next 15 minutes, does something bad actually happen?"
- If no — write it on your capture list and return to current task.
- If yes — note where you are on the current task (next step, blocking issue) so re-entry is fast, then handle the interruption.
- After handling an urgent interruption, give yourself 2–3 minutes to re-read your last output before continuing.
Evidence
Field observation of information workers (Mark, Gonzalez & Harris, 2005) found that interrupted work that was resumed on the same day took an average of about 25 minutes to get back to, with more than two other activities in between. The triage approach is a behavioral intervention targeting this recovery cost. (observational)
The "23 minutes" finding is frequently cited but the sample was small and methodology specific; the directional finding (interruptions impose large recovery costs) is consistent across studies.

Common mistake
Triaging by importance alone rather than also by timing — an important-but-non-urgent task is still worth deferring during a deep focus session.

Attention residue is the focus loss Sophie Leroy documented in her 2009 task-switching study: switch early, and part of your attention stays behind.
- Minimize open tabs and windows during focus sessions
Close all browser tabs and applications not needed for the current task before starting deep work.
- Capture context before every forced switch
When a forced context switch is unavoidable, spend 60 seconds capturing exactly where you are before stepping away.
- Track your actual switch-cost pattern for one week
Measure how long it actually takes you to recover focus after a switch — the data is more persuasive than the concept.
