';The Bell Curve'; by Richard J. Herrnstein and Charles Murray
';The Bell Curve is a controversial, best-selling 1994 book by the late Harvard professor Richard J. Herrnstein and American Enterprise Institute political pundit Charles Murray. Its central point is that the intelligent and their children (the ';cognitive elite';) are affluent due largely to an innate genetic and intellectual superiority to the non-intelligent. Also, the book argued that psychometric intelligence is inversely correlated with human misery. The book had the potential for offending the majority of the U.S. population in that it constitutes a defense of plutocracy and inequality due to race, and it became widely read and debated, especially Chapters 13 and 14, where the authors state that blacks and Hispanics have a lower mean intelligence than whites and Asians due to genetic factors.';





The authors Herrnstein and Murray are the ones who wrote the controversial book and theorized on this data in the mid-90's. And various articles have been published as well as studies conducted to respond to their theores. Search for Nature vs. Nurture.
