If You Can't Explain It Simply, You Don't Get It Yet
The Feynman Technique reveals exactly what you don't understand by forcing you to explain it in plain words, as if teaching a child.
You read the chapter, nodded along, and felt you knew it — until the exam asked why, and you froze. The Feynman Technique, named after physicist Richard Feynman, fixes exactly this trap.
What it is
It's a four-step way to truly learn something: pick a topic, explain it in plain language as if teaching a curious 12-year-old, spot the gaps where you stumble or hide behind jargon, then go back to the source and fill those gaps. Repeat until the explanation flows.
The secret is that teaching exposes understanding far better than re-reading ever can.
Why it works
Re-reading creates a comforting illusion of knowing — the words look familiar, so you assume you've understood them. But the moment you try to explain a concept in your own simple words, every fuzzy spot becomes obvious. You can't fake your way through plain language.
Simplifying also forces you to connect ideas, not just memorise lines. That deeper connection is what survives exam pressure.
How to use it
- Studies: Take a tough concept — say why the trial balance must tally, or how demand and supply set a price — and explain it aloud to an empty chair in everyday Malayalam or Hindi. Where you get stuck is exactly what to revise.
- Studies: Teach a classmate or your younger sibling. If their face says "huh?", your understanding has a gap, not their attention.
- Studies: Write the explanation on one page using small words and a simple example. No copying the textbook line.
- Work: Before a meeting, practise explaining your idea to a non-expert friend. If they get it, your boss certainly will.
- Work: When learning a new tool or process, write a short "how it works" note for a new joinee. Teaching it cements it for you.
- Daily life: Explain a news story — like why prices rise, or how a loan EMI works — to a family member at dinner. You'll quickly learn how well you actually understand it.
Keep a notebook of "things I thought I knew but couldn't explain." That list is your real syllabus.
Understanding is the ability to explain it simply — if you can't, you haven't learned it yet.
