The Feynman Technique
category
The Feynman technique is a four-step learning method: (1) choose a concept, (2) explain it in plain language as if teaching it to a complete novice, (3) identify every point where your explanation breaks down or requires jargon, and (4) return to the source material to fill those specific gaps before re-explaining. The technique ruthlessly exposes the difference between genuine comprehension and the illusion of familiarity.
Role
The single most uncomfortable truth about learning is that most people cannot explain what they believe they know. The moment they attempt to teach a concept simply, without technical jargon or the crutch of restating what they read, the gaps become unmissable. Most people avoid this discomfort entirely by never testing their understanding at the output level. The Feynman technique makes this test unavoidable and turns every gap into a precise instruction for what to study next — converting vague incomprehension into targeted, efficient review.
