Kristof: Rising above IQ

In the mosaic of America, three groups that have been unusually successful are Asian-Americans, Jews and West Indian blacks — and in that there may be some lessons for the rest of us.

Asian-Americans are renowned — or notorious — for ruining grade curves in schools across the land, and as a result they constitute about 20 percent of students at Harvard College.

As for Jews, they have received about one-third of all Nobel Prizes in science received by Americans. One survey found that a quarter of Jewish adults in the United States have earned a graduate degree, compared with 6 percent of the population as a whole.

West Indian blacks, those like Colin Powell whose roots are in the Caribbean, are one-third more likely to graduate from college than African-Americans as a whole, and their median household income is almost one-third higher.

These three groups may help debunk the myth of success as a simple product of intrinsic intellect, for they represent three different races and histories. In the debate over nature and nurture, they suggest the importance of improved nurture — which, from a public policy perspective, means a focus on education. Their success may also offer some lessons for you, me, our children — and for the broader effort to chip away at poverty in this country.

Richard Nisbett cites each of these groups in his superb recent book, “Intelligence and How to Get It.” Dr. Nisbett, a professor of psychology at the University of Michigan, argues that what we think of as intelligence is quite malleable and owes little or nothing to genetics.
