You only keep 5–15% of a video

You watch an hour-long video, and only 5–15% of it stays in your head.

The rest? Gone.

That’s not my opinion. It’s the learning pyramid, which Sabda PS, the founder of the Indonesian learning platform Zenius, talked about on the Malaka podcast.

Why it disappears

Because watching is passive. Your brain only takes things in; it doesn’t work on them. That’s why, after a long video, you go blank when someone asks you to explain it back.

It’s like watching someone else play a game. You know what it looks like, but when you have to play it yourself, you fumble.

Here’s the pyramid, from weakest to strongest:

  • Watching or reading: 5–15% sticks
  • Watching someone do it: about 25%
  • Discussing it: about 50%
  • Doing it yourself: about 75%
  • Teaching it to someone else: about 90%

The point: the more actively you’re involved, the more it sticks.

Why teaching is at the top

Because it forces you to:

  • Put what you understand into an order that makes sense
  • Find analogies so other people get it
  • Notice which parts you don’t actually understand yet

You think you’ve got it, and then someone asks you a question and you realize there are holes.

How to keep more than 15%

  1. Watch or read, but don’t stop there.
  2. Summarize it in your own words. Write down the 3–5 main points.
  3. Put it into practice right away, at work or in a real project.
  4. Explain it to someone else: a post, a voice note, a chat with a friend.
  5. Get feedback. If people are confused, that’s a sign that part isn’t clear in your head yet.

Honestly, writing this was me practicing point 4. I watched, summarized, rewrote it and shared it.

And while writing it, I really did hit parts I thought I understood but couldn’t yet explain simply. That’s the learning pyramid at work.

So next time you finish a video or an article, try explaining it to one person instead of just saving it. For me, that’s what makes it stick.
