Genetic Differences in “g” and Real Life

  • Sandra Scarr
Part of the NATO Conference Series book series (NATOCS, volume 14)


Despite the author’s substantial agreement with the spirit of presentations by Professors Eysenck and Humphreys, arguments about the extremity of their views and their certainty are presented. In the author’s research on twins and adopted children, there are important age differences in the effects of home environments and important differences in the effect of environments on tests of academic achievement, aptitude, and IQ. The confident claims that there is one important general ability and one figure for the heritability of intelligence are disputed.
