We’ve all been there. You attend a class, read a fascinating article, or watch an insightful video…only to forget most of it within days. That frustrating fade in memory isn’t just you being lazy.
In fact, it’s science. It’s called the forgetting curve. If you've ever found yourself asking, "Why do I forget so quickly?" or "Is there a way to actually retain what I learn?", you can learn how to overcome this curve. Let’s explore how to overcome it and remember information for the long haul.
-
What is the Forgetting Curve?
Coined by German psychologist Hermann Ebbinghaus in the 1880s, the forgetting curve describes how we rapidly forget newly learned information over time unless we consciously try to retain it. His research showed that we can lose up to 70% of what we learn within just 24 hours.
The Ebbinghaus forgetting curve shows a sharp decline, a steep drop in memory retention that gradually wears off. However, the good thing is that it's not permanent. With the right strategies, you can flatten the curve and dramatically improve your memory.

Effective Ways to Overcome the Forgetting Curve
-
Use spaced repetition to your advantage
Spaced repetition is your brain’s best friend when it comes to defeating the forgetting curve. Instead of cramming, this technique involves reviewing material at increasing intervals: after a day, then a few days, then a week, and so on.
Various apps and platforms remind you just before you're about to forget something, effectively resetting the curve and helping your brain commit the information to long-term memory.
-
Make learning active, not passive
Re-reading notes isn’t enough. To retain knowledge, your brain needs to work for it. Active recall — the process of testing yourself instead of simply reviewing — has been shown to boost memory retention significantly.
Close your book and try to summarize what you just learned. Teach the concept to someone else. Take practice tests.
-
Connect new knowledge with what you already know
Your brain prefers context. One of the most helpful ways to combat the forgetting curve is to anchor new information to something familiar. For example, if you're learning a new language, link new vocabulary to images, actions, or stories from your own life.
And if you're studying a difficult-to-understand concept, relate it to something you already understand, like comparing electricity to water flow. The more associations your brain makes, the less likely it is to discard that information.
-
Don’t underestimate sleep and breaks
You may not expect it, but one of the most powerful memory tools is sleep. Your brain gathers up memories while you sleep, transferring information from short-term to long-term storage.
Power naps, good sleep cycle, and even short breaks between study sessions or work can make a huge difference. Overworking your brain leads to cognitive overload, making it easier for the forgetting curve to take its toll.
-
Visualize what you learn
Your brain processes visuals 60,000 times faster than text, so turning information into images can make your memory better. Visual learning makes abstract concepts, such as mind maps, diagrams, infographics, or doodles, more concrete and memorable.
Even simple stick figures or color-coded notes can help your brain create stronger neural pathways. This technique boosts retention and also makes recalling information quicker and more intuitive during tasks like tests or presentations.

If you're burning the midnight oil without rest? You're helping the curve, not fighting it. The forgetting curve isn’t your enemy; it’s your brain’s natural filter. But with a few intentional strategies, like spaced repetition, active recall, and quality rest, you can overcome it.
Now that you know what the forgetting curve is, it’s time to use that knowledge to your advantage. Watch how much more you remember. Because the secret to beating forgetfulness isn’t more effort, it’s smarter learning.
