We learn things throughout our entire lives, but we still don't know everything because we forget a lot of information. Why does this happen?
Bright Side decided to learn why this happens and find a way to memorize information much more effectively. There is a universal formula that helps us to memorize things more easily that was made by Hermann Ebbinghaus, a German psychologist. And it works.
Your brain protects you from overloading with useless information. That's why all new information is stored in the short-term memory, not in the long-term memory. If you don't repeat it or use it, you forget it very quickly.
The Ebbinghaus Forgetting Curve shows that just one hour after learning we forget more than half of the learned information. One week later we remember only 20%.
In order to keep the information in your head for a longer time, you need to try to put it into your long-term memory. Forced memorization is not very effective in this case because your brain can't make sense of the information quickly and form strong associations. If you want to remember things for a long time, you need to extend the memorization period. It should be as long as a few days or even weeks.
You can practice interval memorization using self-made cards or special applications like Anki (Android, iOS) and SuperMemo (Android, iOS).
Visualize. Use body language when learning. This will help you trigger your muscle memory.
Choose only the best materials. Don't use outdated books and methods of learning. Things might have changed a lot since the books were written. Don't waste your time on something that may turn out to be wrong.
