General Intelligence (g) and Heritability (H 2, h 2)

  • Chapter

Abstract

As behavior geneticists we find ourselves in the unusual position of representing heredity in a book honoring a pioneer in early-childhood intervention. We are expected to assert the importance of genetics to researchers on the beneficial effects of environmental manipulation. This may not be a particularly popular position, but the facts of individual differences cannot be ignored. People are different, so simple developmental theories become impossible. At the same time, however, we work with behavior as a phenotype and can never forget its plasticity. Just as genotypic uniqueness thwarts hopes for simple theories of development, so the absence of genotype-phenotype isomorphism complicates analogous hopes for simple behavior-genetic analyses.
