How to Learn Anything: The Methods That Actually Work

Why most of us learn the hard way

By Max H. & Philip S., NerdSip Research Team. Both of us hold a PhD in physics and now build a learning app, so we read this research with a personal stake in getting it right.

Ask a room of adults how they study and most will describe the same ritual. Read the material. Highlight the important parts. Read it again. When researchers surveyed 177 college students, 84 percent said they reread, and more than half called it their number one strategy. Only 11 percent said they tested themselves (Karpicke, Butler & Roediger, 2009).

Rereading feels productive because the page gets familiar. Familiar is not the same as remembered. In a classic experiment, students who read a short text four times predicted they would remember it better than students who read it once and then practised recalling it three times. A week later, the readers recalled 40 percent of the ideas. The recallers recalled 61 percent, even though they had read the passage only about a quarter as often (Roediger & Karpicke, 2006).

That gap is the whole subject of this page. How to learn is not a mystery and it is not a talent. It is a handful of methods that feel slightly harder than rereading and work far better, plus a few popular ideas that you can stop wasting time on. Behind all of it sits one stubborn fact, measured first by Hermann Ebbinghaus in 1885 and replicated in 2015: without review, memory decays fast, and most of the loss happens in the first day or two (Murre & Dros, 2015). Our guide to the forgetting curve shows the shape of it. Everything below is about bending that curve.

The method: Recall, Space, Mix, Sleep

The best way to learn, according to the evidence, fits into four moves. Each one is a technique with decades of experiments behind it, not a slogan. Keep these four in mind and you can ignore most study advice on the internet.

Two habits make every move stronger. Explain: ask yourself why something is true and how it connects to what you already know. Picture: where an idea can be drawn, draw it, so you hold it in words and in images. You will find both in the evidence section below.

The four moves share a strange property. Each one makes learning feel harder in the moment and better in the long run. The psychologist Robert Bjork calls these "desirable difficulties". If a study session feels smooth and easy, that is usually a sign you are rereading, not learning.

How to learn effectively: what the science says works

In 2013 five psychologists led by John Dunlosky reviewed hundreds of studies on ten popular learning techniques and rated each one for how useful it is across different learners, materials and test delays. Their report in Psychological Science in the Public Interest is still the best single answer to the question of how to learn effectively (Dunlosky et al., 2013). Only two techniques earned the top rating.

"Low" does not mean useless. It means the benefit was small, unreliable or limited to narrow situations. The two most common study habits in the world sit at the bottom of the table.

Retrieval practice: test yourself before you feel ready

Every time you pull a memory out, you make it easier to pull out next time. A meta-analysis of 188 experiments found that practice tests beat restudying the same material, with a moderate average effect, and that the advantage grew when the final test came more than a day later (Adesope, Trevisan & Sundararajan, 2017). Testing is not just a way to check learning. It is learning.

In practice: after every chapter, lecture or video, close it and write down everything you remember on a blank page. Then check what you missed. Flashcards, practice questions and explaining it aloud to a friend all count. Our guide to active recall and spaced repetition compares the formats.

Spacing: let yourself forget a little

Spacing is the oldest finding in memory research and one of the most reliable. A review of 839 comparisons from 317 experiments found that spreading study sessions out beats massing them together for the same total time (Cepeda et al., 2006). A follow-up with over 1,350 people mapped the best gap: the longer you want to remember something, the longer the gap between reviews should be. To remember a set of facts for a year, the best gap in that study was about three weeks, and the right gap boosted final recall by 64 percent compared with reviewing on the same day (Cepeda et al., 2008).

A simple rule that follows from this: review new material after about a day, again after about a week, and again after a few weeks. Each review will feel rustier than you like. That rust is the point.

Interleaving: mix it up

When students practised maths problems shuffled by type instead of in blocks, they did far better on a test a week later (Rohrer & Taylor, 2007). In another study, people learned to recognise the styles of different painters better when the paintings were mixed than when each artist's work came in a block. Most participants still believed the blocked version had worked better, even after their own test results showed the opposite (Kornell & Bjork, 2008).

Mixing works best for things that are easy to confuse: types of problems, chords, grammar rules, species, styles. Learn each one first, then shuffle.

Elaboration: ask why, then explain it

Asking "why is this true?" and explaining each step in your own words both earned a moderate rating from Dunlosky's team. They work because they tie new information to what you already know, which gives the memory more hooks. The Feynman technique is the most famous version: explain the idea in plain language as if to a twelve-year-old, notice where you stall, and go back to fill exactly that gap.

Dual coding: words plus pictures

Dual coding theory holds that we store information in two partly separate systems, one verbal and one visual, and that material held in both is easier to recall (Clark & Paivio, 1991). Turn a process into a flow chart, a timeline into a drawing, a concept into a labelled sketch. One honest caveat: simply imagining pictures while you read rated low in Dunlosky's review. The benefit comes from building a real diagram, then recalling it.

Sleep: the night shift of learning

Sleep after learning helps the brain stabilise and reorganise new memories (Diekelmann & Born, 2010). Sleep before learning matters too: after a single night without sleep, people showed weaker hippocampal activity while learning new material and remembered less of it (Yoo et al., 2007). Sleep experts recommend at least seven hours a night for adults (Watson et al., 2015). If you are choosing between one more hour of study and one more hour of sleep before something important, the evidence says sleep.

Memory tricks for lists

Mnemonics have their place. The method of loci, or memory palace, is how memory champions remember decks of cards. In one study, 17 people with no memory training practised it for six weeks and more than doubled the number of words they could recall, and they kept most of that gain four months later (Dresler et al., 2017). It is superb for ordered lists, speeches and names. It does not replace understanding. Try it in our memory palace trainer.

Four learning myths you can stop believing

A surprising amount of popular learning advice rests on claims that were never true. Dropping them frees up time for the methods above.

Myth 1: You learn best in your learning style

The idea that you are a visual, auditory or kinaesthetic learner, and should be taught that way, is one of the most widely believed ideas in education. When a team of cognitive psychologists reviewed the evidence, they found almost no studies that tested it properly, and the few that did contradicted it. Their conclusion: there is no adequate evidence base for building teaching around learning styles (Pashler et al., 2008). You do have preferences, and they are worth knowing. Our learning styles quiz shows yours, then points you to what actually helps. The better rule is to match the format to the material: maps for geography, sound for music, hands for a craft.

Myth 2: Speed reading lets you read 1,000 words a minute

A major review of reading research found no shortcut. There is a trade-off between speed and understanding: it is unlikely that you can double or triple your speed, from around 250 to 500 or 750 words a minute, and still understand the text as well. Language skill, not eye technique, is at the heart of reading speed (Rayner et al., 2016). Skimming is a real skill for finding what matters. Reading fast and understanding everything is not. Find out where you stand with our reading speed test, and read the full story on speed reading.

Myth 3: You only use 10 percent of your brain

There is no dormant 90 percent waiting to be unlocked. Brain imaging shows activity throughout the organ, and damage to almost any part of it costs you something. The claim has no traceable scientific source. We take it apart, along with three other brain myths, on our human brain page.

Myth 4: Your attention span is shorter than a goldfish's

The famous "8 seconds, less than a goldfish" statistic was quoted in a 2015 Microsoft Canada marketing report. When the BBC traced it, nobody could find research behind the number, and researchers who study attention did not know where it came from (BBC News, 2017). Attention depends on the task, your sleep and your surroundings, and it can be trained. Read how to improve your attention span, then measure yours with the attention span test.

How to learn when you are busy: a weekly plan

Most adults do not have a semester. They have a job, a commute and maybe half an hour on a good evening. That is enough. The plan below adds up to about three hours a week and uses every move of the method.

Put the demanding sessions where your energy is best, often before work. Put the light ones, like a quick quiz or a five-minute course, into the dead minutes of the day: the queue, the bus, the kettle. That is where most adults find their learning time, and it is time that would otherwise go to scrolling.

Protect each block from interruptions. A timer helps more than willpower does: try 25 minutes of focus followed by a short break, the rhythm of the Pomodoro technique, with our free Pomodoro timer. If focus is the real bottleneck for you, start with the attention span guide or, if you have ADHD, our guide to learning with ADHD.

How to learn anything new, step by step

The weekly plan is the rhythm. These seven steps are the shape of any new subject, from Spanish to statistics to sourdough.

1. Decide what you want to be able to do

"Learn Spanish" is a wish. "Order dinner and chat with the waiter in Spanish by June" is a target. A concrete target tells you what to study and when you are done.

2. Learn the skeleton first

Every field has a few core ideas that everything else hangs on. Find the best beginner book or course and learn those first. The 80/20 rule of learning shows how to find them.

3. Study in short sessions and recall at the end of each

Twenty to forty minutes, then close everything and retrieve. This one habit separates people who remember from people who reread.

4. Explain it in plain words

If you cannot explain it simply, you have found the exact spot you need to study next. Use the Feynman technique.

5. Come back after you have half forgotten

A day, a week, a few weeks. Spaced reviews turn a fresh memory into a lasting one.

6. Mix and apply

Once you know a few pieces, practise them shuffled and in real situations. Use the knowledge to make or do something. That is where the gaps show up.

7. Be patient with the timeline

Basic competence in a new skill takes weeks, real fluency takes months or years. Our honest guide to how long it takes to learn something new has the numbers, and how to learn faster shows where you can save time.

It is never too late to start. Some abilities, like raw processing speed, peak early. Others keep growing for decades: in a study of nearly 50,000 people, vocabulary did not peak until the late 60s or early 70s (Hartshorne & Germine, 2015). Adults also bring something students lack, a large web of existing knowledge for every new idea to attach to.

Mindset, habits and the long game

Methods matter more than mindset, but mindset decides whether you keep using the methods. Carol Dweck's idea of a growth mindset, the belief that ability can grow with effort, is real and useful. The honest footnote is that large meta-analyses found its average effect on school results to be small, with clearer benefits for some groups, such as students from poorer backgrounds or those at risk of failing (Sisk et al., 2018). Believing you can learn helps. Using retrieval and spacing is what actually does the learning.

The rest is habit. People who keep learning for decades tend to read a lot, write things down, ask questions and protect time for practice. We collected the evidence in habits of highly successful people and habits of smart people, and the practical version in how to get smarter. If you are choosing what to learn for your career, start with high income skills and the skills that stay valuable as AI improves.

Where NerdSip fits

We built NerdSip for the dead minutes of the day, and we built it around the methods on this page. You type anything you want to learn, from how vaccines train the immune system to the rules of chess, and the app generates a short course on it. A five-lesson course takes about five minutes. Every lesson ends with a quiz question, so the recall step is built in rather than left to willpower. On the Plus and Pro plans, a spaced repetition review in the Repetition tab brings back courses you finished, oldest first. Courses go through several fact-checking layers, which reduce mistakes but cannot rule them out, so treat it like any good source.

It will not replace a textbook, a teacher or a year of practice. It is the easiest way we know to fill the gaps in a day with real learning instead of scrolling.
