Steve Sailer has written an important macro-level review of Richard Lynn's Race Differences in Intelligence: An Evolutionary Perspective, which makes an interesting companion to Jason Malloy's micro-level critique that was posted on GNXP a couple of months back.
From Sailer's review:
How do high IQ people rationalize to themselves suppressing mention of national differences in average IQ—especially when they spend so much time thinking about how they, personally, are smarter than other people?
A common stratagem, I've found, is to assume that IQ differences matter only if they are genetic in origin. Since no decent, civilized, right-thinking person could possibly believe that racial differences in IQ have any genetic basis, then racial and national differences in average IQ can't possibly exist.
Except—they do exist.
And, as I will show that—no matter what their origin, whether in nature or nurture or both—these IQ gaps will continue to exist for many decades.
