Have you ever crammed a load of facts into your brain the night before stressfully, but still got an F? That isn’t too surprising. Everybody’s highly likely to forget newly learned things within a matter a time. This comes from a statement from the Ebbinghaus Forgetting Curve. The Ebbinghaus Forgetting Curve is a memory-based curve designed by German psychologist Hermann Ebbinghaus defined in his book Memory.
Approximately, 3 days after learning something, 40% of the information is lost. If it is reviewed after 1 day, it will take longer to forget. Two days after reviewing, if it is reviewed again, it will take much longer to forget than when the information was first reviewed. According to another source, most information is lost only shortly after it is learned.
In the simplest terms, the number of times a block of information is reviewed can make a difference on whether the learner forgets the information or not. The learner may forget all of the information after a long time if it is reviewed three times, for instance, but it will never forget if it is reviewed for 100 times, day after day.
