Feynman Technique Explained: Master Any Skill by Teaching It Like a 12-Year-Old

This is the Brain Hacks Podcast. Ever find yourself staring at the same page of a book for twenty minutes, reading the words but retaining absolutely nothing? Well, today I'm going to share a ridiculously effective brain hack that sounds like something out of a spy novel, but it's backed by solid neuroscience. It's called the Feynman Technique, named after the legendary physicist Richard Feynman, who was basically the rockstar of science in his day. Here's the beautiful simplicity of it. When you want to truly master any concept, any skill, or any piece of information, you explain it out loud as if you're teaching it to a curious twelve year old. Not dumbing it down, mind you, but stripping away all the jargon and complexity until you hit the pure core of understanding. Let me walk you through exactly how this works. Say you're trying to learn about how the stock market functions. Step one, grab a blank piece of paper or open a blank document. At the top, write the concept you're studying. Step two, and this is where the magic happens, write out an explanation using the simplest language possible. Pretend you're talking to a kid who's smart but has zero background knowledge. No fancy terms, no insider language. If you find yourself wanting to use a technical term, stop and define it in plain English first. Step three is where you identify the gaps. As you're writing or speaking your explanation, you'll hit walls. You'll realize you're using circular logic or you don't actually understand why something works the way it does. These are your knowledge gaps, and they're absolute gold. Mark them clearly. Step four, go back to your source material, but this time with laser focus on filling those specific gaps. You're not just rereading everything. You're hunting for the exact pieces you're missing. Then you return to your explanation and refine it. Step five, and this is my favorite part, simplify your language even further. Use analogies. Compare the stock market to a farmers market where prices change based on what people want to buy. Make it vivid and concrete. Why does this work so well? Your brain is incredibly good at fooling you into thinking you understand something when you've really just memorized the surface. Neuroscientists call this the illusion of competence. When you force yourself to teach a concept, you activate completely different neural pathways. You're not just recognizing information anymore. You're reconstructing it from scratch, which builds much stronger and more flexible mental models. The act of identifying what you don't know is equally powerful. Most people avoid this discomfort, but it's actually where all the growth happens. You're making your ignorance visible and specific, which means you can actually do something about it. Try this tomorrow with anything you're learning. Spend fifteen minutes explaining it out loud to an imaginary curious kid, or even better, to your actual friend or family member. Watch how many times you stumble or realize you're hand waving over the hard parts. Those stumbles are your brain literally rewiring itself to accommodate deeper understanding. The best part about the Feynman Technique is that it compounds. The more you practice explaining things simply, the better your brain gets at organizing information efficiently. You'll start noticing patterns across different subjects and building connections you never saw before. And that is it for this episode. Please make sure you subscribe to never miss an episode.
