Heritability estimates versus large environmental effects: the IQ paradox resolved.

Psychological review - 1 Apr 2001

Dickens W T, Flynn J R

Abstract excerpt

Some argue that the high heritability of IQ renders purely environmental explanations for large IQ differences between groups implausible. Yet, large environmentally induced IQ gains between generations suggest an important role for environment in shaping IQ. The authors present a formal model of the process determining IQ in which people's IQs are affected by both environment and genes, but in which their...
