CORE DEFINITION

If a task you need to do takes less than two minutes (e.g., replying to a short message, washing a cup), don't put it on your to-do list; do it immediately.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Prevents small tasks from piling up. It instantly clears the brain's "open loops," preventing countless micro-tasks from accumulating into a huge psychological burden, keeping workflow smooth.

anchor

Anchor fast decisions

Proposed by David Allen in GTD: tasks that can be completed within 2 minutes should be done immediately, not entered into the to-do system. The mechanism is: the management cost of recording/tracking a micro-task often exceeds the cost of directly executing it; immediately clearing "open loops" avoids the accumulation of a large number of micro-tasks into psychological burden and decision fatigue.
