1. Herrnstein and Murray ignore the large body of research showing limitations of IQ. e.g., that many successful (and wealthy) people do not have high IQ. There's much more to intelligence than what IQ measures. Some research shows lower success of very high IQ people.

  6. The cultural and societal landscape of the USA is such that the poor grow up with substandard housing, poor nutrition and high crime and drugs. Survival depends upon the development of adaptive skills, but not those like IQ. Statistics - graphs, correlations, are predicated on this landscape. If the landscape were different, so might be the test results

  7. [Testing intelligence is difficult and is subject to the constraints of the testing medium] What factors affect performance on intelligence tests? familiarity with content e.g. vocabulary; anxiety; testing context e.g. familiar environment; assessment method e.g. individual (questions asked and answered orally, given privately) or group test (pencil and paper test requiring reading and writing, given in group); degree of development of thinking learning skills; and the relationship between the tester and the testee e.g. same vs. different ethnicity. (Shapiro, 1973).
