How long can you retain what you have read, seen, or heard? Obviously, every individual has his or her own capacity to retain any information in their minds. Some may forget almost everything within the first 48 hours, while others can retain the information for years together.
But, broadly, people forget a lot of information in the first 48 hours, after which the rate of loss decreases as ideas are moved into long-term memory. Considering this rate of memory loss, there’s a “Forgetting Curve” that is used to identify how people retain or lose information that they encounter every day. What is the Forgetting Curve? Way back in the 19th century, there was a psychologist names Hermann Ebbinghaus. This was the time when higher mental processes were seen as beyond the scope of traditional science, which is why Hermann wanted to investigate the way human beings remember and forget information. He did so by conducting a simple experiment on himself. For several weeks, he gave himself a task of remembering and reciting some nonsensical absurd words. He measured his performance over time, which helped him uncover his rate of memory loss. He plotted the same on a graph, which is now known as the “Forgetting Curve”.
