This notion of a decline in memory over time is known as the forgetting curve, and it was developed by Herman Ebbinghaus in 1885.

…you’ll be able to retain this piece of geographic trivia in memory for an even longer period, let’s say up to one hour.Īnd if we continue to proceed in this manner, where I keep reminding you the capital of Colombia is Bogotá precisely at the moment you’re about to forget, the time in between memory lapses grows exponentially from hours to days, then to months, then to years.Īnd eventually, as the theory goes, the knowledge - that Bogotá is the capital of Colombia - will be more or less permanently lodged in your memory. After which you’ll forget.īut, if I remind you again 39 minutes and 59 seconds later that… …spaced repetition theory says you’ll be able to remember Bogotá is the capital of Colombia for now say 40 minutes. After which you’ll forget.īut, if at 19 minutes and 59 seconds, while we’re having a cup of coffee, I remind you… Let’s assume your memory is such that you’ll remember this new fact-that the capital of Colombia is Bogotá-after your very first exposure to it, for a clean 20 minutes. And suppose right now I tell you what the capital of Colombia is. It holds that the ideal moment to remember a new piece of information is at the moment you are about to forget it.įor example, suppose you don’t know the capital of Colombia. Spaced repetition seeks to solve the problem of forgetting.

If you do so, you’ll get to the point where can’t forget details.” Googley as Heck, who studied full-time for 8 months for a Google interview, says “ Spaced repetition is the key to memorization…You become an expert by revisiting and reviewing over time.Jeopardy! champion Robert Craig says he owes some of his success to using Anki for memorizing trivia.Many have attested to the benefits of spaced repetition:
