This work offers a perspective on the causes of the social and economic problems that plague contemporary America. It examines the relationship between ethnicity and intelligence and presents the view that America's population is becoming polarized between an educated elite and uneducated poor.

The controversial New York Times national bestseller--now updated with a comprehensive response to critics. Covered on front pages around the world--reviled, praised, defended, and deplored--this seminal examination of the relationship between ethnicity and intelligence has "kicked up more reaction than any other social-science book of this decade" (David Brooks, The Wall Street Journal).

In the second round of reaction, some commentators suggested that Herrnstein and Murray were merely bringing up facts that were well known in the scientific community, but perhaps best not discussed in public. A Papua New Guinea language has a term for this, Mokita.
