The Forgetting Curve: Why Coaches Need to Repeat 3 Times
You deliver a great training session. Three weeks later: 80% is forgotten. Sound familiar? This is the forgetting curve — and there is a proven solution.
What Is the Forgetting Curve?
Hermann Ebbinghaus discovered in 1885 that our brains forget information exponentially fast if we don't repeat it. After 1 day, an average of 50% is gone. After a week, 80%.
Spaced Repetition: The Counterattack
- Repetition 1: 1 day after the lesson
- Repetition 2: 3 days later
- Repetition 3: 1 week later
- Repetition 4: 3 weeks later
- After 4 repetitions: knowledge is in long-term memory
