How to Retain Information Better With Science-Backed Strategies

If you want to remember what you learn, you need to stop just reviewing information and start actively engaging with it. This means pulling information out of your brain (active recall) and revisiting it at specific, spaced-out times (spaced repetition). This one-two punch is the most effective way to combat the brain's natural tendency to forget what it doesn't use.

Why We Forget and How to Fight It

We’ve all been there. You read an insightful book or sit through a crucial meeting, and a week later, the key takeaways are completely fuzzy. This isn’t a personal flaw; it’s just how our brains are wired. They're built for efficiency, which means they’re constantly clearing out information they don't think is important or actively used.

This phenomenon was mapped out way back in the 19th century by psychologist Hermann Ebbinghaus. Understanding his work on the Forgetting Curve is the first step toward building a better memory. It shows, in stark detail, how quickly we lose new information—often within hours or days—unless we deliberately do something to reinforce it.

The Myth of Passive Learning

For decades, most of us were taught to study by rereading, highlighting, and re-watching lectures. These methods feel productive, but they're a trap. They create what researchers call an "illusion of competence." You recognize the material and feel familiar with it, but when you actually need to recall it from scratch, you come up empty.

The real secret to retaining information is to treat your memory like a muscle. It doesn’t get stronger from watching; it gets stronger from the active effort of lifting and retrieving.

The good news is that remembering is a skill, not a fixed talent. This guide will help you ditch those ineffective habits and build an active learning toolkit. The strategies here are backed by solid evidence and can turn learning from a fleeting event into a lasting upgrade for your brain. And don't forget, quality rest is a huge part of this process—check out our guide on how to improve sleep quality naturally to see how sleep locks in new memories.

A Roadmap to Stronger Retention

Before we dive deep, here’s a quick overview of the core techniques we’ll be exploring. Think of this as your roadmap for the journey ahead.

Quick Guide to Better Information Retention

This table summarizes the core memory-boosting techniques discussed in this article, their primary function, and a simple real-world application to start using today.

Technique	What It Does	Try This Today
Active Recall	Strengthens memory by forcing your brain to retrieve information without looking at the source.	After reading this section, close the page and explain the "forgetting curve" out loud in your own words.
Spaced Repetition	Interrupts the forgetting process by reviewing information at strategically timed, increasing intervals.	Set a calendar reminder to review your explanation of the forgetting curve tomorrow, in three days, and then in a week.
Elaboration	Connects new information to your existing knowledge, creating a rich network of mental hooks for easier recall.	Think about a time you quickly forgot something important. How does that experience relate to the forgetting curve?
Interleaving	Mixes different but related topics during a study session to improve long-term retention and problem-solving skills.	If you're learning two new software features, practice switching back and forth between them instead of mastering one at a time.

These methods form the foundation of a powerful learning system. Let's get into how to put each one into practice.

Mastering Active Recall and Spaced Repetition

If you really want to upgrade your ability to remember things, you have to stop being a passive observer. Highlighting passages and rereading your notes might feel productive, but honestly, it's just creating an illusion of competence. The real gains come from two powerhouse techniques backed by solid science: Active Recall and Spaced Repetition.

Think of active recall as a mental workout. It's the act of pulling information out of your brain, not just cramming it in. It’s the difference between staring at a map of your city versus trying to draw it from memory. That little bit of struggle to remember something actually strengthens the neural pathways, making the memory stick.

Putting Active Recall into Practice

You can weave this technique into just about anything you're trying to learn. The goal is to constantly test yourself in small, low-stakes ways.

• After a meeting? Don't just scan your notes. Instead, take five minutes and jot down the three most important takeaways from memory. Then go back and check your notes to see what you missed.
• Reading a book? When you finish a chapter, close it. Try to explain the main points out loud, like you're telling a friend about it. This is a real-life application known as the Feynman Technique, which forces you to simplify and solidify your understanding.
• Learning a new skill? If you're figuring out a new piece of software, try to do a task without watching the tutorial again. The effort you spend trying to recall the steps is exactly where the deep learning happens.

This isn't just a nice idea; it's incredibly effective. Research has shown time and again that this kind of retrieval practice demolishes simple rereading for long-term retention. One study found that students who tested themselves on material recalled 21% more information a week later than students who just studied it over and over. You can dig into the findings of this testing effect study yourself. The effort is what seals the memory in.

Doubling Down with Spaced Repetition

So, active recall makes your memories stronger. But Spaced Repetition is what makes them last. This technique is all about interrupting the brain’s natural tendency to forget. You review information at specific, increasing time intervals. The logic is simple: reviewing something right before you're about to forget it is the most efficient way to lock it in for the long haul.

This is the "forgetting curve" in action. Without a little nudge, new information fades shockingly fast.

As you can see, the drop-off is steep. Each time you review the information at the right moment, you flatten that curve, pushing the memory further and further into the future.

Comparing Active Recall and Spaced Repetition

While these two techniques are the perfect partners, they do different jobs. Getting the distinction will help you use them more effectively.

Aspect	Active Recall (Retrieval Practice)	Spaced Repetition (Spaced Practice)
Core Function	Strengthens a memory by forcing your brain to retrieve it.	Maintains a memory by timing reviews to stop you from forgetting.
The "When"	Right after learning something and during any review session.	At increasing intervals—over days, weeks, and eventually months.
Real-World Example	Testing yourself with flashcards.	The schedule you follow for reviewing those flashcards.

Active recall is the heavy lifting that builds the memory muscle. Spaced repetition is the smart training schedule that ensures your gains are permanent.

Creating a Simple Spaced Repetition System

You don't need fancy software to get started. A simple schedule is all it takes.

• First Look (Day 1): Within 24 hours of learning something, do your first active recall session.
• Second Pass (Day 3): Come back to the material three days later. It should feel a bit easier this time.
• Third Check-in (Day 7): Review it again after a week has passed.
• Fourth Review (Day 16): Push the next review out even further.

As you get into the rhythm, tracking your schedule can help you stay on course. If you need some help building the habit, check out our guide on the best habit tracking apps to find a tool that works for you.

By combining the deliberate effort of active recall with the smart timing of spaced repetition, you create a system that works with your brain's natural wiring. This powerful duo is the foundation of learning how to retain information for good.

Go Beyond Rote Memorization with Elaboration and Interleaving

Active recall and spaced repetition are your workhorses for getting facts to stick. But if you want to achieve true mastery and not just robotic memorization, you need to go deeper. This is where we bring in two incredibly powerful techniques: Elaboration and Interleaving.

Think of them as the next level of learning. They help you build a rich, interconnected web of knowledge in your brain, making information not just memorable, but genuinely useful.

Weave New Knowledge into Your Existing World with Elaboration

So, what is elaboration? It's the simple, but profound, act of asking "why?" and "how?" It’s about consciously connecting new information to things you already understand.

Instead of treating a new concept as a lonely, isolated fact, you find a home for it in your existing mental library. This creates multiple pathways to that memory, so when you need to pull it up later, your brain has several routes to get there. It’s the difference between just knowing a fact and truly getting it.

To start using elaboration, make a habit of asking yourself a few simple questions whenever you encounter something new. Let's imagine you're learning about a new project management tool, maybe something like Monday.com, at work.

• Don't just memorize the features. Instead, ask: How is this fundamentally different from the Trello boards we’ve been using?
• Connect it to your own experiences. Think back and ask: Could this have helped us avoid that communication mess on the Q3 project last year? How?
• Explain it back to yourself (or someone else). Try to put the main benefit into your own words: Okay, so this really solves our biggest headache—seeing how tasks in my department affect the marketing team's timeline.

This simple shift in approach turns you from a passive sponge into an active participant in your learning. You’re not just remembering; you’re understanding and integrating. This kind of thinking is the bedrock of real growth, and it ties directly into what it means to build a growth mindset that embraces challenges.

Elaboration transforms learning from a chore of memorization into an act of integration. You're not just storing facts; you're updating your entire mental model of the world.

The Power of Mixing It Up with Interleaving

Now for the second key ingredient: Interleaving.

This technique involves mixing up different, but related, topics or skills within a single study session. It’s the complete opposite of the way most of us were taught to learn—the "blocked practice" method, where you drill one thing until you've "mastered" it before moving on.

I'll be honest: interleaving feels harder in the moment. And that's the point. When you force your brain to switch between different types of problems, it has to work harder to retrieve the correct strategy each time. That struggle is precisely what builds flexible, long-term knowledge. It teaches your brain how to choose the right tool for the job, not just how to use one tool over and over.

Real-Life Example: A student learning different types of math problems (e.g., algebra, geometry, statistics) would benefit more from a mixed practice test than from doing 20 algebra problems, then 20 geometry problems. The mixed test forces them to identify the type of problem first, which is a crucial real-world skill that blocked practice ignores.

Blocked Practice vs. Interleaving: A Comparison

The difference in results between these two approaches is striking, especially when you look at long-term retention. Blocked practice can give you a false sense of confidence during the study session, but interleaving is what actually builds skills that last. This table breaks down why.

Aspect	Blocked Practice (Studying one topic at a time)	Interleaving (Mixing related topics)	Which is Better for Retention?
The Process	Master concept A, then master B, then master C.	Practice a mix of A, B, and C in the same session.
Short-Term Feel	Feels easy and productive. Performance is high during the session.	Feels difficult and slow. You might make more mistakes initially.
Long-Term Retention	Leads to rapid forgetting and poor performance on mixed tests.	Dramatically improves long-term recall and problem-solving.	Interleaving
Real-World Example	A pianist practicing the same scale for 30 minutes straight.	A pianist practicing scales, chords, and arpeggios in rotation.

By weaving these two methods into your routine—using elaboration to build deep context and interleaving to build flexible problem-solving skills—you’ll move far beyond just trying to cram facts into your head. You'll start building a foundation of true, applicable knowledge that sticks around for the long haul.

Make Information Stick by Using Visuals and Stories

Let's face it: our brains aren't built to memorize endless pages of text or abstract data. We’re wired to understand the world through images and narratives. Tapping into this hardwired preference is one of the most effective shortcuts for making new information truly stick.

This isn't just a feeling; it’s a well-known cognitive principle called the picture superiority effect. The name says it all—we remember pictures far better than words. Visuals give our brains a much more direct and efficient path to long-term memory.

Why Visuals Work So Well

The magic of visuals lies in how our brains are built. Reading text activates the language centers, which is a fairly focused activity. But when you look at an image, your brain lights up multiple areas at once, including the visual cortex and the hippocampus, which plays a huge role in forming memories.

This creates a richer, stronger memory. One Stanford study highlighted just how powerful this is, finding that younger participants remembered 65% more details from images than from text. Even a full 24 hours later, their recall was still 40% higher. The research also suggests our brains process visuals up to 60,000 times faster than text, which explains why a good diagram can make a complex idea click almost instantly. If you want to dig deeper, you can explore more about the study's findings on visual memory.

Simple Ways to Put This into Practice

You don't need to be a graphic designer to make this work. The goal is just to turn abstract ideas into something you can see.

• Try Mind Mapping: Next time you’re in a webinar, ditch the linear notes. Put the main topic in the center of a page and draw branches for key ideas. Use different colors or simple doodles to show how concepts connect.
• Sketch Simple Diagrams: Trying to get your head around a complicated process? A quick flowchart can work wonders. Even a rough sketch of boxes and arrows can clarify a sequence far better than a dense paragraph.
• Use Infographics: When you’re staring at a spreadsheet full of numbers, try to find or create a simple infographic. Seeing data as charts or graphs immediately highlights trends and comparisons that are easy to miss in a table. For some inspiration, check out our guide on finding the right images for your project.

Turn Facts into Stories You Won't Forget

Beyond static images, our brains are complete suckers for a good story. A narrative—with a clear beginning, middle, and end—gives our minds a natural framework to hang facts on, engaging us both logically and emotionally.

Real-Life Example: Instead of trying to cram isolated project stats into your brain, weave them into a story.

Don’t just memorize "Q3 revenue increased by 15% after the marketing campaign."

Instead, tell yourself the story: "Our team was facing a flat growth forecast (the challenge). So, we launched a new, targeted campaign (the action), which blew past expectations and led to a 15% revenue spike (the result)."

This simple reframing adds context and transforms a forgettable data point into a memorable achievement.

Visuals vs. Text: Knowing When to Use Each

Both approaches have their strengths. The key is knowing which tool to pull out of your toolbox for the job at hand.

Aspect	Text-Based Learning (e.g., Reading a report)	Visual & Narrative Learning (e.g., Mind mapping the report)
Brain Engagement	Primarily language processing centers.	Multiple brain regions, including visual cortex and emotional centers.
Processing Speed	Slower; requires decoding symbols into concepts.	Extremely fast; concepts are grasped almost instantly.
Retention Rate	Lower; highly susceptible to the forgetting curve.	Significantly higher; creates stronger, more durable memory traces.
Best For	Conveying detailed, nuanced information precisely.	Explaining complex systems, relationships, and data trends quickly.

By consciously translating dense information into visuals and stories, you start working with your brain's natural tendencies instead of against them. This one shift in your approach can make a world of difference in how well you learn and remember just about anything.

Build a Lifestyle That Supports Your Memory

All the learning techniques in the world won't stick if your brain isn't in a state to receive them. We can talk about fancy study methods all day, but they’re only half the equation. The other half is your lifestyle—the way you eat, sleep, move, and handle stress.

Think of it like building a house. You wouldn't put up expensive walls on a cracked, unstable foundation. Your daily habits are the foundation for your memory. Let’s get that right first.

Sleep: The Ultimate Memory Consolidator

Sleep isn’t just about resting your body; it’s prime time for your brain to get to work. While you’re asleep, your brain is busy sorting through the day's experiences, filing away important information, and strengthening new neural connections. This is when memories move from fragile, short-term storage to more permanent long-term archives.

Real-Life Example: Imagine you spent the afternoon learning a new programming language. That night, during deep sleep, your brain replays the neural patterns associated with that learning, effectively transferring the knowledge from your short-term "inbox" (the hippocampus) to your long-term "hard drive" (the cortex). Trying to learn on too little sleep is like closing the program before hitting 'Save'.

Fuel Your Brain with the Right Nutrition

Your brain is incredibly demanding. It uses about 20% of your body's calories, so what you eat directly impacts its performance. You wouldn't put cheap fuel in a high-performance car, so don't do it to your brain.

You don't need a complex diet plan. Just focus on adding more of these brain-friendly foods:

• Omega-3 Fatty Acids: Think fatty fish (like salmon), walnuts, and flaxseeds. These are the literal building blocks for your brain cells.
• Antioxidants: Found in berries, leafy greens, and even dark chocolate, they protect your brain from wear and tear.
• B Vitamins: Eggs, whole grains, and legumes help your brain produce the chemicals it needs to function properly.

Making small, consistent changes to your diet is a long-term investment in your cognitive health. If you're looking for inspiration, our guide on micro-habits that transform your life has some great ideas for getting started.

Your brain is always 'on.' The choices you make at the dinner table directly translate to your ability to focus, learn, and remember tomorrow.

Move Your Body to Grow Your Brain

Exercise is one of the most powerful things you can do for your brain. Getting your heart rate up with a brisk walk, run, or swim sends a fresh rush of oxygen and nutrients to your brain.

Even better, it triggers the release of growth factors that actually help create new neurons, especially in the hippocampus—the brain's memory hub. You don't need to run a marathon; a simple 20-minute walk can be enough to boost memory and information processing.

Stress Management as a Memory Strategy

Chronic stress is a memory-killer, plain and simple. When you're constantly stressed, your body is flooded with cortisol. In small doses, it's fine, but over time, high levels of this hormone can actually damage the hippocampus, making it harder to form new memories and recall old ones.

Think of managing stress not as a 'soft skill' but as a core learning strategy. A few simple practices can make a huge difference:

• Mindfulness: Just a few minutes a day can lower cortisol and sharpen your focus.
• Deep Breathing: It's the fastest way to hit the brakes on your body's stress response.
• Getting Outside: Spending time in nature is a proven way to reduce stress and reset your mind.

By weaving these four pillars—sleep, nutrition, exercise, and stress management—into your daily routine, you're creating the perfect biological environment for learning to happen. It's about making sure your brain is ready and able to hold onto all the information you work so hard to put into it.

Your Action Plan for Better Information Retention

Knowing the theory is one thing, but putting these ideas into practice is where you'll see real change. The trick is to start small so you don't get overwhelmed. Just pick one new technique to try this week, use it consistently, and once it feels natural, layer on another. Think of it as building a muscle—improving how you retain information is a skill you can develop over time.

This isn't just an abstract exercise. Building these mental skills is more important than ever, especially as self-reported cognitive issues have nearly doubled for 18-39-year-olds to 9.7%. The good news? Education acts as a proven shield for memory. One fascinating study across 10 European countries revealed that more years of schooling were linked to 15-20% better delayed recall scores, creating a buffer against age-related decline.

Let's look at how this plays out in the real world.

Scenario 1: A Student's Weekly Study Schedule

Instead of cramming for one subject all day, a smart student can blend spaced repetition and interleaving to make their study time far more effective. It feels a bit harder in the moment, but the payoff is huge for long-term memory.

Here’s what that might look like:

• Monday: Dive into Chapter 1 of History for an hour. Then, completely switch gears and spend the next hour working through math problems. Right before bed, take 15 minutes to actively recall the main points from that history chapter without looking at your notes.
• Wednesday: Start with a quick 15-minute review of Monday's history concepts. Then, spend 45 minutes on Chapter 2. After that, tackle a mix of math problems from both Monday and today's lesson.
• Friday: Pull it all together with a rapid-fire review of the week's history and math topics using flashcards or by quizzing yourself.

Scenario 2: A Professional's Webinar Strategy

You just sat through a 90-minute webinar packed with great information. How do you make sure it doesn't all vanish by tomorrow? The key is to combine active recall with a simple mind map.

Don't try to transcribe the webinar word-for-word. That's just passive listening. Instead, listen for the big, overarching ideas and sketch them out in a rough mind map. As soon as the webinar ends, close your laptop and force yourself to write down the three most important, actionable takeaways from memory. That act of pulling the information out of your brain is what cements it.

For those looking to build a more robust system for capturing and recalling knowledge, exploring something like the Second Brain Method can be a game-changer. It gives you a structured way to organize everything you learn.

Scenario 3: A Lifelong Learner's Book Retention

Do you ever finish a fantastic non-fiction book, only to realize a week later that you can barely remember the key arguments? The Feynman Technique is perfect for this.

After you finish a chapter that really made you think, grab a blank piece of paper.

Now, pretend you have to explain the core concept to a 12-year-old. Write it out using the simplest language you can. You’ll immediately discover where your understanding is fuzzy. This is the magic moment. Go back to the book to fill in those gaps, then try your simple explanation again. This process transforms you from a passive reader into someone who deeply understands and retains the material.

Frequently Asked Questions

1. If I can only focus on one technique, which one gives the most benefit?

If you're going to start with just one technique, make it Active Recall (also known as retrieval practice). The simple act of pulling an answer from your brain—instead of just rereading it—is the single most powerful action you can take to strengthen a memory. It provides the biggest return on your time investment.

2. How quickly can I expect to see improvements in my memory?

You will feel the immediate benefit of strengthening a specific memory the first time you use active recall. However, for a noticeable, general improvement in your ability to retain information, consistent application of these techniques (like active recall and spaced repetition) for 2-4 weeks will build the habit and start showing significant results.

3. Is it better to take notes with a pen and paper or on a laptop?

Both have distinct advantages. Pen and paper is often better for initial learning, as the physical act of writing forces your brain to process and summarize information. Digital notes are superior for long-term storage, organization, and searchability. A powerful hybrid approach is to take initial notes by hand and then digitize the key concepts into a spaced repetition system like Anki.

4. How does multitasking affect my ability to retain information?

Multitasking is a significant barrier to retention. When you divide your attention, your brain cannot perform the deep "encoding" process required to move information into long-term memory. To remember something effectively, you must give it your focused, undivided attention.

5. What is the ideal study session length for maximum retention?

Research overwhelmingly supports shorter, focused sessions over long "cramming" sessions. A series of 25-50 minute sessions (like the Pomodoro Technique) with short breaks in between is far more effective than a single multi-hour marathon. This approach prevents mental fatigue and gives your brain time to consolidate what you've learned.

6. Can lifestyle changes like diet and exercise really make a difference?

Absolutely. Your brain is a biological organ. High-quality sleep is when memory consolidation primarily occurs. Nutrients like Omega-3s are the building blocks of brain cells. Exercise increases blood flow and growth factors in the brain. Think of these habits as the foundation—without them, even the best learning techniques will be less effective.

7. What is the "Feynman Technique" and how can I use it?

It's a simple method for deep understanding. First, choose a concept. Second, explain it in simple terms as if you were teaching a child. Third, identify the gaps in your explanation where you struggle or use jargon. Fourth, go back to the source material to fill those gaps, then simplify your explanation again. This process ensures you truly understand the material, not just recognize it.

8. How do I apply these techniques if I have a very busy schedule?

These methods are about working smarter, not longer. Use "in-between" time for learning. Turn a 5-minute coffee break into a quick active recall session with flashcards on your phone. While commuting, try to mentally summarize the key points of a meeting. The goal is to integrate frequent, small retrieval efforts into your existing day.

9. Are some people just naturally bad at remembering things?

While there are genetic variations, memory is far more of a skill than an innate talent. People who appear to have a "good memory" are often unconsciously using principles like elaboration and active recall. By deliberately practicing the techniques in this guide, anyone can significantly improve their ability to retain information.

10. Do memory-enhancing supplements or "brain games" actually work?

The scientific evidence for most commercial brain games and supplements is weak, especially for long-term benefits in healthy adults. The most proven and effective "enhancements" are not pills or apps, but the foundational techniques discussed here: active recall, spaced repetition, and a healthy lifestyle (especially sleep and exercise).
