Clear the capture inbox regularly

Process and file captured notes on a weekly basis so the inbox stays a temporary landing zone, not a storage bin.

Why it works

An unprocessed capture inbox generates the same cognitive tension as an unprocessed email inbox: the brain registers many unresolved items that require a decision. Weekly processing — filing each capture into its PARA location or deleting it — converts the inbox from a pile into a current, trusted system. The processing step is also when light layer-one highlighting happens, deepening the engagement with each note.

How to do it

1. Set aside 15–20 minutes weekly (often during the weekly review) to process all new captures.
2. For each item: does it belong in a project, area, resource, or can it be deleted?
3. Do a light layer-one highlight on items you are keeping — mark the sentence that made you save it.
4. Do not let the inbox grow past one week of captures without a processing pass.

Evidence

Consistent with GTD’s weekly review and open-loop research: unprocessed inboxes are unresolved decisions that accumulate cognitive load. Regular processing maintains the system’s trustworthiness, which is the mechanism that allows genuine mental offloading. Masicampo and Baumeister found that simply making a concrete plan for an unfinished task — without completing it — eliminated the intrusive thoughts it otherwise provoked, which is precisely what filing a capture into its place accomplishes. (mechanistic)

The optimal processing frequency is individual — some people process daily, others weekly. The key is consistency, not a specific cadence.

Common mistake

Letting the capture inbox grow for months without processing, so it becomes a source of anxiety rather than relief and the system stops being trusted.
