Proposes six points
1. There is a general factor of cognitive ability on which humans differ
2.All standardized tests of academic aptitude or achievement measure this general factor to some degree
3.IQ scores match, to a degree, whatever people mean when they use the word intelligence or smart in ordinary language
4.IQ scores are stable, although not perfectly so, over much of the lifespan
5. Properly administered IQ tests are not demonstrably biased against social, economic, ethnic, or racial groups
6. Cognitive ability is substantially heritable, apparently no less than 40 percent & nor more than 80 percent
