Scott Alexander examines the effectiveness of education by analyzing knowledge retention, questioning the value of schooling beyond basic skills. 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.
