Design capture systems to minimize time-to-externalization

Design capture systems to minimize time-to-externalization rather than optimizing for downstream organization, because working memory decay begins within seconds and compounds with each additional step.

Why This Is a Principle

This is a design principle that follows from multiple axioms: Working Memory Capacity Limit (working memory holds 3-5 items), Exponential Information Decay (decay rate of ~42% in 20 minutes), and Directed Attention as Depletable Resource (cognitive resources deplete with use). It prescribes how to design capture systems given these constraints. It's general enough to apply across contexts but specific enough to be actionable.

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.
