Offload peripheral information to free working memory

Write things down externally so working memory is free for thinking, not storage.

Why it works

Working memory is a processing system, not a storage system. Using it to hold information you do not actively need — a phone number while writing an email, the steps already done in a recipe, a list of errands — leaves less capacity for the task at hand. Offloading to paper or a trusted system eliminates the storage demand and lets processing proceed at full capacity.

How to do it

1. Keep a running external capture system so anything requiring future action leaves working memory immediately.
2. Write out all the steps of a complex task before beginning so you are not holding them in mind during execution.
3. During thinking-intensive work, jot intermediate results rather than retaining them mentally.

Evidence

The value of external working-memory offload is well supported by distributed cognition research and by cognitive load theory; holding unnecessary items in mind demonstrably degrades concurrent task performance. (mechanistic)

This is a mechanistic inference from working-memory capacity constraints rather than a specifically studied intervention. The basic capacity limits are well established.

Common mistake

Relying on memory to hold task details during complex work because writing them down "takes too long" — failing to account for the ongoing processing cost of retaining them.
