Run a weekly review

Once a week, process inboxes and review every project and list to keep the system trusted.

Why it works

A capture system only quiets the mind as long as the mind trusts it is current — the moment lists go stale, the brain resumes holding loops as backup. The weekly review re-establishes that trust by clearing inboxes, updating project lists, and confirming every commitment has a next action, so the system stays the reliable external memory the whole method depends on.

How to do it

1. Block a recurring time and protect it the way you would a meeting.
2. Empty all inboxes, then review every project to confirm each has a defined next action.
3. Scan your calendar, waiting-for, and someday lists to recalibrate priorities for the coming week.

Evidence

The review is the linchpin practitioner ritual of GTD; its value is interpreted from the system’s logic and user experience rather than isolated in controlled trials. It aligns with the broader finding that the relief of offloading depends on the external system being trustworthy and current. Research on cognitive offloading shows that reliance on an external store tracks how much the person trusts it, which is exactly the currency the weekly review exists to maintain. (mechanistic)

There is little direct experimental evidence on the weekly review specifically; its necessity is argued from the mechanism that trust requires currency.

Common mistake

Skipping the review when busy — which is exactly when lists go stale, trust erodes, and the whole system quietly stops working.
