 According to Murray and Herrnstein:
The Bell Curve Flattened Charles Murray is a publicity genius, and the publication of his and Richard Herrnstein's book, The Bell Curve: Intelligence and Class Structure in American Life , in the fall of 1994 was his masterpiece. (For example, back in 1991, Murray somehow got hold of the galleys of my own last book, and wrote me heatedly denying that he was working on a book about black genetic intellectual inferiority, as I had asserted. The people who had galley proofs were handpicked by Murray and his publisher. Another handpicked group was flown to Washington at the expense of the American Enterprise Institute and given a weekend-long personal briefing on the book's contents by Murray himself (Herrnstein had died very recently), just before publication. The result was what you'd expect: The first wave of publicity was either credulous or angry, but short on evidence, because nobody had had time to digest and evaluate the book carefully. Most works containing fresh regression analysis and historical argument from primary sources would be published in academic quarterlies that send manuscripts out for elaborate, lengthy evaluation before deciding whether to publish them. Herrnstein and Murray didn't do this, so it wasn't until a full year or more after The Bell Curve was published that the leading experts on its subject had a chance to go through the underlying data with care. The debate on publication day was conducted in the mass media by people with no independent ability to assess the book. IQ tests, according to Murray and Herrnstein, measure an essential human quality, general intelligence.
 Poor black people are unintelligent.
 Poor black people are unintelligent.  Poor people are able to work hard and get ahead.  There are different types of intelligence.  Successful people are clustered among the unintelligent.
