The third member of the committee is the big surprise, and the big problem: Christopher Jencks, for decades a leading figure among liberals who did serious research on inequality—a contributor to the New York Review, the author of important books including Inequality: Who Gets Ahead?; The Homeless; and The Black White Test Score Gap. Christopher Jencks knows exactly what’s wrong with the studies purporting to link “race” with “IQ.”

Richwine concluded his dissertation, “From the perspective of Americans alive today, the low average IQ of Hispanics is effectively permanent.” Why would Christopher Jencks decide that that dissertation was worth a Harvard Ph.D.? I asked Jencks whether he would comment. He replied “Nope. But thanks for asking.”

No less than Rush Limbaugh has cited the approval of the dissertation by Christopher Jencks, “a renowned left-wing academic,” as proof that the young man is being railroaded.

Fortunately, like a lot of leftists (other than the handful who have actually studied the subject, such as Christopher Jencks), Weiner knows that while science has proven that we all have the same IQ, he also knows that people who don't know that have been scientifically proven to be of lower IQ:

The last word in this story goes a study published in 2012 the journal Psychological Science. “In an analysis of two large-scale, nationally representative United Kingdom data sets (N = 15,874),” the researchers wrote, “we found that lower general intelligence (g) in childhood predicts greater racism in adulthood.”
