Yes it does, it's one of the most widely cited studies for IQ research. My uni had the class do a research project based on this study, you might just be looking at the wrong page.
It doesn't, see attached screenshot of tests carried out on the cohort.
There are fields of biology that were largely discarded due to its racist foundations, (does eugenics ring any bells to you?).
IQ is a predictor of outcome only once you have discarded every other variable, I don't see why such a weak predictor is being so stringently defended by you.

The use of ASVAB score as a stand-in for IQ is contentious amongst researchers.
1 2 3 4 5
What's more, higher scores on WAIS and ASVAB are even less correlated with eachother than lower scores.

Still sifting through the data myself to have a look, but this study seems to suggest it doesn't (at least with educational outcomes).

It does show that g is a poor predictor for educational outcomes.
And this study shows that g doesn't correlate well with wealth.
And this one suggests socioeconomic background has a similar impact on educational outcomes to cognitive ability.
So, what "life outcomes" is IQ supposed to be so much better at predicting that we can safely ignore its racist baggage?

Also when I talk about racist baggage, I don't mean that some racists use IQ as an excuse for racism. I mean IQ testing was popularised by eugenicists looking for excuses to do eugenics.
