Richard Lynn - The Global Bell Curve
In The Bell Curve Richard Herrnstein and Charles Murray (1994) showed that in the United States there is a socioeconomic hierarchy of race and intelligence. They showed that whites are at the top of this hierarchy with the highest average IQ (103) and the highest socioeconomic status and earnings. Hispanics come next with an average IQ of 89 and intermediate socioeconomic status and earnings. Blacks come last with the lowest average IQ of 85 and the lowest socioeconomic status and earnings. They argued that the racial socioeconomic hierarchy is largely determined by differences in intelligence.
The present book examines how far this thesis holds for other multiracial societies. In many countries throughout the world there are racial inequalities in earnings and socioeconomic status. We consider how far these too can be explained by racial differences in intelligence.
