ユダヤ人の IQ が高い理由:都市生活の影響

引用



Urban Upgrade ? 80-90% of Jews were farmers in 1 AD. But only 10-20% remained in agriculture by 1000 A.D. The education required by Joshua ben Gamla’s edict delivered verbal and math skills to Jewish boys, enabling them to move out of subsistence rural life into highly-skilled urban professions, involving sales, trade, and financial transactions.
Moving from a pastoral environment into cities implements an IQ boost, due to urbanism’s increased complexity, literacy, and technology. A Hanoi National University study in 2006 showed a whopping 19.4 IQ difference between city and country students. A 1970 survey in Greece recorded a difference of 10-13 points. Other studies note smaller discrepancies of only 2-6 points, but unanimously, urban residents always score higher, and Jews are one of the world’s longest-urbanized ethnicities.
