 What is the problem with using IQ to predict economic success?
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. Because intelligence is substantially inherited, nothing is likely to reverse this process.
