Genetics Is Undercutting the Case for Racial Quotas

“I am worried,” writes Harvard geneticist David Reich in The New York Times, “that well-meaning people who deny the possibility of substantial biological differences among human populations are digging themselves into an indefensible position, one that will not survive the onslaught of science.”

Reich was responding to anticipated resistance to his forthcoming book, “Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past.” The “well-meaning people” Reich references are those who argue that race is a “social construct,” that there are no significant genetic differences among people of different racial ancestry. {snip}

Reich obviously wishes to avoid the demonization endured by Murray, who was shouted down at Middlebury College just last year. Reich is at pains to say that his findings should not be used to justify racist practices, such as the slave trade, the eugenics movement and the Holocaust.

The assumption of “well-meaning people” is that ordinary Americans aren’t capable of grasping this. My view is that they understand it very well. They have learned — from school, from work, from everyday life, from public events — that there is a wider variation within each measured group than there is among measured groups.

It’s a strong argument. Contrary to the fears of “well-meaning people,” the difference in average racial IQ scores does not undermine the case against racial discrimination. Ordinary Americans can and do see that racial discrimination against individuals is irrational and that the advances in knowledge about genetics by Reich do not make it any less so.

But the continuing existence of racial gaps, even as the IQ scores of all groups rise (that’s the Flynn effect, identified and named by Herrnstein and Murray), does undercut the case for racial quotas and preferences and the “disparate impact” legal doctrine established by the Supreme Court 47 years ago.

The justification for quotas is the assumption that in a fair society, we would find the same racial mix in every school, every occupation and every neighborhood. Any significant deviation from statistical equality, in this view, can be evidence of persistent racial discrimination.

This notion suffuses the behavior of leaders in colleges and universities, in large corporations, in government at all levels. Many such leaders regard enforcing quotas as a moral duty, even if they place people in positions for which they’re unprepared. For these “well-meaning people,” David Reich has a (probably unintentional) warning: Science is undermining the rationale for the work you’re doing.
