Intellectual potential and heredity.
When infant developmental quotients are compared with children's intelligence quotients, it appears that most subnormality is manifested only at the later age. This phenomenon has been cited as evidence that environment chiefly determines intelligence, but the argument is circular. A helpful approach to the nature-nurture problem is afforded by the geneticists' concept of reaction norms or "reaction repertoires."
