Race and IQ Pushback
By Arnold Kling
Most important, we know that interventions at every age from infancy to college can reduce racial gaps in both I.Q. and academic achievement, sometimes by substantial amounts in surprisingly little time. This mutability is further evidence that the I.Q. difference has environmental, not genetic, causes. And it should encourage us, as a society, to see that all children receive ample opportunity to develop their minds.
I would like to see Nisbett and James Heckman debate the empirical evidence. My impression is that Heckman is not quite so sanguine about educational interventions, and Heckman is an optimist compared to other folks I know.
