Minimize open tabs and windows during focus sessions

Close all browser tabs and applications not needed for the current task before starting deep work.

Why it works

Open tabs and visible notifications generate "external attention residue" — the visual presence of other tasks activates their associated goal representations, creating a low-level competition for attentional resources even when the tabs are not being clicked. Reducing the visual field to only current-task materials removes these competing activations and lowers the stimulus-driven switching that undercuts sustained focus.

How to do it

1. Before beginning a focus session, close all browser tabs not needed for that session.
2. Use a dedicated workspace or virtual desktop for focus sessions — different from your "normal" desktop.
3. Use a browser extension or app (e.g., full-screen mode, site blockers) to further narrow the environment.
4. Treat re-opening a distraction tab as a conscious, logged exception rather than a reflexive habit.

Evidence

Research on environmental cues shows that objects and visual stimuli associated with competing goals activate those goals automatically — a priming effect that generates attentional pull toward them. Reducing the field of view to current-task materials directly applies this mechanism. (mechanistic)

The priming mechanism is well established in general; the specific application to browser tabs is a principled extrapolation rather than directly studied.

Common mistake

Leaving email and Slack open "minimized" during focus sessions — minimized windows still generate notification badges and sounds that trigger the same orienting response.
