Ideology can make a fool out of otherwise creditable scientists. The way that the remarkable temperature stability of the 20th century (according to the U.N. only .6 of one degree rise over the entire 20th century) can be portrayed as an era of global warming is ample proof of that.

And James Flynn is another example of that. He does generally good science and knows heaps about IQ research but when it comes to interpreting scientific findings which clash with his faith he goes bananas. He is a fervent Leftist — with all the faith in being able to “mould” people into some sort of ideal man that usually goes with that faith. And genetic influences have a nasty unalterable character that clashes with that faith.

So what does he do when faced with an unremitting torrent of research findings that show a consistent black/white gap in average IQ of around 15 points? He points to just ONE study which shows no significant gap. And that study must be just about the most irrelevant one in the literature. He points to a study which shows that the illegitimate children of black GI’s in Germany are no dumber than the illegitimate children of white GI’s in Germany.

I don’t know how to put this politely, but, as far as I can see, all that that result shows is that German women don’t go to bed with dumb blacks. They only go to bed with the brighter ones. And the U.S. army of the 40s and 50s was a good place to find the brighter ones. Blacks had to be at least as bright as whites to get into the U.S. army of the 40s and 50s. Ever since 1917, the U.S. army has accepted only those recruits who pass an IQ test at a standard level. And there have always been SOME blacks who pass. So Flynn bases his faith in the unreality of black/white IQ differences on a sample which has been deliberately equalized in terms of IQ! What a fool! I can think of no other term for him that fits.

You can find detailed accounts of Flynn’s follies in the matter here and here. In his most recent posts, Chris Brand also points out the limitations of the study Flynn relies on. I have commented previously in the academic literature on explanations for his own findings that Flynn does not consider. See here and here.
