Summary

Chapter 2 epigraph the overwhelming evidence that there are major genetic influences on intelligence and its development. Conclusive studies from quantitative and molecular genetics leave no doubt about this. Since genes always work through biological mechanisms, there must be a neurobiological basis for intelligence, even when there are environmental influences on those mechanisms. Polygenic scores based on DNA can predict IQ.
