Elizabeth Chin has written an excellent scholarly takedown, in the form of a “letter from your thesis reader,” of Jason Richwine’s 2009 Harvard PhD dissertation, ” IQ and Immigration.” I’ve not read Richwine’s thesis, though I probably will at some point. And you probably haven’t either. But, you’ll still find Chin’s post informative and compelling.…

It is, of course, true that a correlation does not in and of itself…

Average Brain Size for the Three Races

Philipe Rushton, in his book Race, Evolution and Behavior, reports average brain size for the three races. The following is the graph from Rusthton’s book:

Well, yes. But the question raises some interesting points.

This is Chart 1 from Race, Evolutoin and Behavior by J. Philippe Rushton, originally published in the Unabridged Edition of same.

Why Human Brains Vary

Many people assume human brains vary genetically and genetic variation maps to races. But the races are not real and genetic variation can’t explain brain differences. Because, dear reader, brains don’t work that way. Let’s look just at the brain part of this problem.

This post started out as a comment that would have gone here (but would have done just as well here). But it became sufficiently long and possibly interesting that I figured it would make a good, if somewhat rough, blog post.
