Spaced Repetition
Review over expanding intervals to resist forgetting.
Explanation
Hermann Ebbinghaus discovered that we forget most new information incredibly quickly—about half within the first hour and 70% within a day. But here's the key: each time you review something, it takes longer to forget. By spacing reviews at increasing intervals, you can move information from short-term to permanent memory.
Real-World Example
Cramming for test: Remember for 3 days, forget everything. Spaced repetition: Remember for years. Language apps like Anki users learn 10,000+ words permanently. One study: Spaced practice = 200% better retention than massed practice.
How to Apply
Use spaced repetition apps (Anki, SuperMemo). Or simple system: New cards daily, review at increasing intervals. When easy, increase interval. When hard, reset to day 1. 20 minutes daily > 3 hours weekly. Consistency beats intensity.
