 What is the problem with using IQ to predict economic success?
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. 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. 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. Because intelligence is substantially inherited, nothing is likely to reverse this process. Any efforts government might make to improve the economic opportunities of poor people, especially poor black people, are likely to fail, because their poverty is so much the result of inherited low intelligence. Herrnstein and Murray begin by telling us that the liberal position on IQ--namely, "Intelligence is a bankrupt concept"--has been discredited, and that "a scholarly consensus has been reached" around their position.
 IQ tests are impacted by the amount of education a person has had
 IQ tests are not aimed at people of all races  IQ tests are impacted by the amount of education a person has had  IQ tests aren't all the same, so it's not a fair control  IQ tests only test inherited intelligence
