Longer summary
Scott Alexander analyzes the effectiveness of education by examining how much factual knowledge people retain after schooling. He presents survey data showing that many adults, including college students, struggle to recall basic facts taught in school. The post explores why this might be, discussing the Ebbinghaus Forgetting Curve and spaced repetition. Scott proposes that people mainly remember information they encounter regularly in daily life, rather than what they learned in school. He concludes by questioning the usefulness of most schooling beyond basic skills, suggesting that cultural osmosis might be more effective for long-term knowledge retention.
