Separate capture from organization into distinct cognitive operations that never overlap, because working memory cannot handle both classification and preservation simultaneously.
Why This Is a Principle
Directly derives from Working Memory Capacity Limit (working memory holds 3-5 items) and Cognition Operates Through Dual Processing Systems (System 1 vs System 2 processing). The principle prescribes architectural separation of two operations that compete for limited cognitive resources. This is highly actionable and applies across all knowledge work contexts.
Source Lessons
First capture, then organize
Capture and organization are separate cognitive operations. Merging them creates friction that kills both: you lose the thought while searching for where to put it.
Capture must be frictionless
If capturing a thought takes more than a few seconds, you will not do it consistently — and inconsistent capture means permanent information loss.
