Where the term comes from
Reviewed by Risko and Gilbert in Trends in Cognitive Sciences (2016), building on earlier work on epistemic actions and computational offloading.
Why it matters
It is the general mechanism underneath brain dumping, calendars, shopping lists and notes. The value is not organisational tidiness — it is reducing what working memory must hold.
The common mistake
Offloading capture but not decisions. A written but unranked list has offloaded the remembering and left the deciding in your head, which is often the expensive half.
What it looks like in practice
