CORE DEFINITION

Test whether you truly understand a concept by trying to explain it in the simplest terms to someone with no background knowledge (e.g., an 8-year-old). If you get stuck, go back and relearn.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The ultimate tool for internalizing knowledge. It forces you to break through the disguise of jargon and turn inert knowledge into living understanding, serving as the gold standard for distinguishing 'understanding' from 'memorization'.

The Feynman Technique advocates explaining concepts in the most accessible language to someone with no background knowledge (e.g., a child), thereby exposing gaps in understanding; wherever you get stuck is where you need to go back and relearn. It uses 'being able to explain clearly' as the test for true mastery.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Choose a concept, assume you are teaching it to a layperson, and write out a plain-language explanation. Wherever you find it hard to explain smoothly, go back to the source and relearn. Remove jargon, simplify analogies, until it flows.
