In Italy, north-south differences in IQ predict differences in income,education, infant mortality, stature, and literacy

摘要

Regional differences in IQ are presented for 12 regions of Italy showing that IQs are highest inthe north and lowest in the south. Regional IQs obtained in 2006 are highly correlated withaverage incomes at r= 0.937, and with stature, infant mortality, literacy and education. Thelower IQ in southern Italy may be attributable to genetic admixture with populations from theNear East and North Africa.
