Forgetting Curve
A hypothesis that describes the decline of memory retention in time. It shows how information is lost over time when there is no attempt to retain it.
The Forgetting Curve, hypothesized by Hermann Ebbinghaus, illustrates that we tend to halve our memory of newly learned knowledge in a matter of days or weeks unless we consciously review the learned material.
Combatting the Curve
The most effective way to flatten the forgetting curve is through Spaced Repetition. By reviewing material at increasing intervals, you reset the curve, retaining the information for longer periods each time.
