I started in the 1970′s and never quit. Lately I donât read much about it because I pretty much made up my mind a long time ago. I still hold out hope that it might be amenable to a closing of the gap, but I get less and less certain over time.
If you spend as much time researching the gap as I have, after a while, the conclusion that it must be generally keeps on punching you in the face. It knocks you down over and over. People who study it that much and still say itâs environmental have pretty much been KOâd 1000′s of times and are standing up once again to fight George Foreman and lose.
I donât talk about much on here, and officially, my line is only that at the moment in the US, Whites are more intelligent than Blacks by about 13.2 points.
Through a lot of fancy messing around with statistics and some journalistic license, I was able to shave a couple of points off the standard 1 SD gap, but I realize thatâs not particularly scientific, only that one can make the case by choosing certain tests. Chuck agrees with me that adult Blacks have shaved ~1.5 points off the gap, we both agree that Black kids have shaved ~5-6 points off the gap.
I would argue that IQ tests are a valid measure of intelligence, and that at the moment, Whites are smarter than Blacks on average. Officially, I am not saying what is causing the gap, but we ought to be discussing the fact that itâs real.
