Batch all reactive tasks into defined windows
Reply to email, messages, and minor requests only in scheduled windows — not continuously.
Key takeaways
- What it is: Reply to email, messages, and minor requests only in scheduled windows — not continuously.
- Why it works: Switching between focused work and reactive tasks incurs attention residue: a portion of attention stays on the previous task, degrading performance on both. Batching collapses many context-switches into a single transition, dramatically reducing the residue cost. It also eliminates the cue-response loop that makes real-time notification checking habitual.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Setting the batching rule but leaving notifications on — which means every ping still interrupts attention even if you don’t respond, negating the residue benefit.
Why it works
Switching between focused work and reactive tasks incurs attention residue: a portion of attention stays on the previous task, degrading performance on both. Batching collapses many context-switches into a single transition, dramatically reducing the residue cost. It also eliminates the cue-response loop that makes real-time notification checking habitual.
How to do it
- 1Choose 2–3 windows per day for reactive work (e.g., 10 am, 2 pm, end of day).
- 2Turn off email and message notifications outside these windows.
- 3In windows, process reactively; outside windows, anything reactive waits.
- 4Communicate the schedule to colleagues with a brief auto-responder or direct note the first week.
What the evidence says
ObservationalAttention residue research (Sophie Leroy) found measurable performance decrements from task-switching, supporting batching as a way to reduce switching costs. Email checking frequency has also been studied in relation to stress.
Honest caveat: Both studies are observational or experimental in lab/diary contexts; real-world batching depends on job type and organizational culture. Not all roles can batch — some require real-time responsiveness.

Common mistake
Setting the batching rule but leaving notifications on — which means every ping still interrupts attention even if you don’t respond, negating the residue benefit.
