Lynn, R. (2008). The Global Bell Curve. Augusta, GA: Washington Summit Publishers.
ISBN: 1-59368-028-7.

This builds on Richard Herrnstein and Charles Murrays (1994) The Bell Curve in which they showed that in the United States intelligence (IQ) is an important determinant of educational attainment, earnings, and socioeconomic status. They showed that in this hierarchy Europeans do best, Hispanics come next and Afro-Americans do poorly. The Global Bell Curve extends this analysis worldwide and shows that the same hierarchy is present in numerous multi-racial countries throughout the world. It also extends the analysis to Jews and East Asians who invariably do well, and to Native American Indians who do poorly. It concludes that IQ is a key explanatory variable for the social sciences, analogous to gravity in physics.
