Richard Lynn's new book shows that in many multi-racial countries, people of Jewish and East Asian ancestry average highest in IQ and socio-economic position, Whites next highest, South Asians and Hispanics next highest, and people of African descent consistently average at lower levels. Lynn argues that the average population group differences in socio-economic position (education levels, earnings, welfare dependency) are due to their average differences in intelligence. Since these differences also translate into fertility patterns, with the lowest IQ populations having more children, the specter of a dysgenic future is raised. Altogether the issues are discussed separately across 13 countries or areas of the world: the United States, Africa, Australia, Brazil, Britain, Canada, the Caribbean, Hawaii, Latin America, the Netherlands, New Zealand, and Southeast Asia.
