renorming

This was before the infamous 1996 renorming (and subsequent ~20 point drift) so it actually equates to, say, 1190 - 1280 in todays metric.

He then brings up the Flynn effect, which is the observation that absolute IQ scores are steadily increasing across different societies although the rates vary in each country, necessitating a renorming in IQ tests.

So, to test this, I asked Charles Murray to take a look at the most recent renorming of the U.S. military's IQ test that all applicants for enlistment must take, the Armed Forces Qualification Test or AFQT, and he graciously obliged, sending me some new and important data that I have not seen reported before.

Interestingly, that was down from the anomalously large 18.6 point black-white gap found on the 1980 renorming of the AFQT a recent meta-analysis of over 100 IQ studies covering over 6 million individuals found an average black-white gap of 16.5 points.

The renorming was done on the 1997 National Longitudinal Study of Youth, a large scale sample of people approximately aged 15-23, I believe.

So, here is the data from the U.S. military's 1997 renorming of the AFQT on computers, as provided to me by Charles Murray, "using the 1997 cohort AFQT converted to an IQ metric, and employing population weights to reach nationally representative results."

To get around this, in the 1997 renorming of the AFQT, the test was given on a computer and if you missed a lot of the early questions, the computer would feed you easier questions to keep you from giving up.

Slate says blacks are dumber than average! Steve Sailer 2005

As Murray noted in his recent Commentary article see Footnote 41, the previous renorming of the AFQT in 1980 now appears to have underestimated average black IQ, reporting an improbably large 18.6 point gap between the races, due to low-scoring blacks, especially black males, being more inclined to give up partway through the daunting 105 page pencil-and-paper test and not even trying to answer the remainder of the questions.
