What is the Feynman Technique? The 4-step formula to learn anything faster

Learning is a lifelong journey—whether you're a student gearing up for exams or a professional getting ready for an important presentation, effective learning and memorising require the right technique.

If you’ve ever crammed facts only to forget them days later, the Feynman Technique offers a cleaner, more durable approach. Named after physicist Richard Feynman, who was famed for explaining difficult ideas in simple terms, the method forces you to translate complexity into plain language and then fix what you can’t explain.

At its core the technique follows four straightforward steps: Study, Teach, Fill the Gaps, Simplify.

• Start by learning the topic normally (read, watch, take notes).
• Then try to teach it—out loud or in writing—as if your audience is a beginner.
• When you hit an explanation you can’t give clearly, go back to the source material, close the knowledge gap, and repeat—paring language down each time until the idea is obvious.

Why It Works

The Feynman Technique converts passive consumption into active processing. By forcing yourself to explain concepts in simple words, you quickly surface what you don’t actually understand. This prevents illusion-of-knowledge—where you think you know something because you recognise the words—while helping you build mental models that stick. Studies and educators often recommend active recall and teaching as superior to rereading, and this method packages both into an efficient loop.

How To Apply It

• Pick one topic (e.g., a concept in economics, grammar rule, or algorithm).
• Write a plain-English explanation on a single page—no jargon. Imagine you’re teaching a teenager.
• Record yourself explaining it, or teach a friend; the act of speaking exposes weak spots.
• When stuck, return to the source (textbook, lecture, video), then rewrite your explanation.
• Use analogies and simple diagrams—they’re memory glue.

Common Mistakes To Avoid

• Don’t replace deep study with oversimplified metaphors—use them to clarify, not to conceal gaps.
• Avoid passive rereading; the Feynman Technique only helps if you actually produce an explanation.
• Keep iterations short and focused—20–40 minutes per cycle yields better retention.

15 min — read/watch and take rough notes.

20 min — explain aloud or write the concept in simple terms.

10 min — identify gaps and review targeted material.

15 min — re-explain and simplify; add analogies or a diagram.

The Feynman Technique is deceptively simple but powerfully effective; when you can teach a concept clearly, you truly understand it. Use it regularly and you’ll find studying stops feeling like a chore and starts producing real, lasting knowledge.
