The forgetting curve is Hermann Ebbinghaus's general theory for how long we can retain information, defined by a formula for how long items will remain in a person's memory. A graph of this formula shows the forgetting curve, which describes how much information is lost over time, specifically when there is no attempt to retain it (see photo). According to Ebbinghaus, how well you retain information depends on the strength of your memory and the amount of time that has passed since you learned that information.
