question:  What was the basic purpose of The Bell Curve?
context: 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. The Bell Curve was not circulated in galleys before publication. The effect was, first, to increase the allure of the book (There must be something really hot in there!), and second, to ensure that no one inclined to be skeptical would be able to weigh in at the moment of 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. The Bell Curve isn't a typical work of trade nonfiction. It is gotten up as a work of original scholarly research. 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. Therefore, as time went on, the knowledgeability of the Bell Curve discussion grew, but the attention paid to that discussion inevitably shrank. The debate on publication day was conducted in the mass media by people with no independent ability to assess the book. It wasn't until late 1995 that the most damaging criticism of The Bell Curve began to appear, in tiny academic journals. The Bell Curve , it turns out, is full of mistakes ranging from sloppy reasoning to mis-citations of sources to outright mathematical errors. IQ tests, according to Murray and Herrnstein, measure an essential human quality, general intelligence. During the second half of the 20 th century, this quality has risen to supreme importance, because society has become increasingly complex. The intelligent have therefore gone through an "invisible migration," from points of origin all over the class system to a concentration at the top of business, government, and the professions.
