Learning How to Learn
Deliberate practice showed how to train a skill at the edge of your ability. But before you can practice a skill, you usually have to learn something — a language, a body of theory, a craft’s vocabulary — and get it to stay in your head. Here’s the strange part: the study methods that feel most effective are often the weakest, and the ones that feel like a struggle are the ones that work. Learning how to learn means trusting the evidence over the feeling. Done right, it’s one of the highest-leverage skills there is, because it speeds up every other thing you’ll ever pick up.
The principle: make your brain work to remember
Section titled “The principle: make your brain work to remember”For over a century, cognitive psychology has been quietly converging on a handful of techniques that reliably help people learn faster and remember longer. A few of them are among the most replicated findings in the entire field. The headline is counterintuitive: the harder your brain works to pull information back out, the better it sticks. Easy, smooth study feels great and teaches little.
Four techniques carry most of the weight:
- Spacing (distributed practice). In 1885 Hermann Ebbinghaus, testing his own memory, mapped the forgetting curve — newly learned material drops away fast at first, then levels off. The fix isn’t to study harder in one sitting; it’s to spread study across time. Reviewing something across several spaced sessions beats cramming the same total minutes into one block. A large review (Cepeda, Pashler, Vul, Wixted, and Rohrer, Psychological Bulletin, 2006) confirmed the spacing effect across hundreds of experiments. Each time you let yourself almost forget and then pull it back, the memory gets stronger.
- Retrieval practice (the testing effect). Trying to recall something — closing the book and answering from memory — is not just a way to check learning; it causes learning. In a landmark study, Roediger and Karpicke (Psychological Science, 2006) had students study a passage, then either restudy it or take a recall test. On a delayed final test, the testing group remembered far more — even though the restudying group felt more confident. The act of retrieving rewires the memory more than re-exposure does.
- Interleaving. Instead of practicing one type of problem in a block (AAAA, then BBBB), mix them up (ABCABC). It feels worse and slower in the moment, but it teaches your brain to tell problems apart and choose the right approach. Kornell and Bjork (Psychological Science, 2008) found students who saw painters’ works interleaved learned to recognize each artist’s style better than those who studied one artist at a time — though they were sure the blocked method had worked better. (Interleaving’s benefit is strongest for related skills you’ll later have to distinguish, like math problem types, so it’s a bit more situational than spacing and retrieval.)
- Elaboration. Don’t just memorize a fact — connect it to what you already know, and explain why it’s true in your own words. The most famous version is the Feynman technique, named after physicist Richard Feynman: pick a concept and explain it in plain language as if teaching a beginner. The gaps where you stall or reach for jargon are exactly the parts you don’t actually understand yet.
The thread tying these together is a single idea from psychologist Robert Bjork: desirable difficulties. Conditions that make learning feel harder now — spacing it out, testing yourself, mixing things up — produce stronger, more durable, more flexible learning later. The struggle isn’t a sign the method is failing; it’s the mechanism. Much of this is gathered, readably, in Make It Stick (Brown, Roediger, and McDaniel, 2014), the best single book on the topic.
FEELS PRODUCTIVE (weak) FEELS HARD (strong) ────────────────────── ─────────────────── re-read the chapter -> close it and recall it highlight the page -> test yourself, then check cram the night before -> space reviews over days study one topic in a block -> interleave related topics nod along: "I know this" -> explain it out loud, simplyThe practice: convert one thing to retrieval and spacing
Section titled “The practice: convert one thing to retrieval and spacing”Take one thing you’re learning right now — a chapter, a language’s vocabulary, a concept for work — and run it through the two highest-value techniques:
- Read once, then close it. Read the material a single time with full attention. Then close the book and write or say everything you can recall — out loud or on paper, from memory.
- Check and mark the gaps. Open the book and compare. The things you missed or got wrong are your real study list — not the whole chapter, just the holes. This is where almost all the learning is.
- Explain it simply (the Feynman step). Take the hardest idea and explain it as if to a curious twelve-year-old, in plain words. Where you stall or fall back on jargon, you’ve found a gap. Go relearn that piece, then explain it again.
- Space the reviews. Don’t restudy it all tonight. Recall it again tomorrow, then in a few days, then in a week — each time from memory first, checking after. Lengthen the gaps as it gets easier.
- Interleave if it applies. If you’re learning several related things (problem types, verb tenses, chord shapes), mix them in practice instead of drilling one to death before moving on.
The most common mistake by far is confusing recognition with recall — re-reading until it feels familiar and calling that studying. Familiarity is the trap. If you haven’t closed the book and produced the idea from nothing, you don’t yet know whether you know it. The whole game is replacing “looks familiar” with “I can generate this.”
How to tell it’s working: it will feel worse than your old method, at least at first. Recall is effortful and a little frustrating, and you’ll be tempted to flee back to the comfortable glow of re-reading. That discomfort is the signal you’re doing it right — it’s a desirable difficulty. The other tell is on the back end: days later, you can still produce the material without the book, where the old re-reading you would have quietly evaporated.
The challenge
Section titled “The challenge”For one week, study only by retrieval and spacing — ban re-reading and highlighting as your main method. After every reading, close the book and recall. Review on a spacing schedule (tomorrow, in three days, in a week) instead of cramming. It will feel slower and harder than your usual approach, and you’ll doubt it midweek. Test yourself at the end against how much you’d normally retain. Most people are startled by how much more sticks — and by how badly the comfortable old method was fooling them.
Reflect
Section titled “Reflect”- Think about how you usually study or learn something new. Is it mostly re-reading and reviewing (recognition), or closing the book and recalling (retrieval)?
- Recall a time you felt totally prepared and then blanked — on a test, in a meeting, in a conversation. Could the fluency illusion have been at work?
- Have you ever sorted yourself as a “visual” or “hands-on” learner? How might that label have steered you away from methods that work for everyone?
- Where in your life do you cram — squeezing learning into one block right before you need it? What would spacing it out look like?
- Pick one thing you’re learning now. What’s the very next desirable difficulty you could add — a recall attempt, a spaced review, an out-loud explanation?
Show reflections
- Most honest answers land on recognition — re-reading feels like studying because it’s smooth and familiar. Noticing that is the first step to swapping in retrieval, which feels worse but works.
- Blanking after feeling prepared is the fluency illusion’s signature: you recognized the material while studying but never practiced producing it. The cure is to rehearse the actual act you’ll need — recall, not review.
- The label itself is the problem. Believing you “learn by X” can make you avoid the broadly effective methods. There’s no harm in preferring a format, but the evidence says everyone learns by spacing, retrieval, interleaving, and elaboration.
- Cramming works for a day and fails for a month, because it fights the forgetting curve instead of using it. Even splitting the same total time into two or three spaced sessions dramatically improves what survives.
- The best answer is small and slightly uncomfortable: close the book and recall, schedule one spaced review, or explain the hardest idea out loud in plain words. Any one of them beats another re-read.
