Black intellectual genocide

Girma Berhanu reviews the book IQ and the Wealth of Nations, written by Richard Lynn and Tatu Vanhanen. He critiques the authors’ major assertion that a significant part of the gap between rich and poor countries is due to differences in national intelligence. The authors claim that they have evidence that differences in national IQ account for substantial variation in per capita income and growth of a nation. This essay review debunks their assumptions that intellectual and income differences between nations stem from genetic differences.
