Do you know what the threshold was before and after the lowering?
That one time the US military decided to lower standards. https://www.amazon.com/McNamaras-Folly-Low-IQ-Troops-Vietnam-ebook/dp/B0108H60MG …pic.twitter.com/ui6UoGXbHp

30th centile by us whole population norms. Down to 10th.
-
Right, but then the Wiki article also says ppl "below IQ 80" were newly admitted. 30th is not IQ 80, I think.
-
10th centile is 80 IQ (in R, use `qnorm(.1, 100, 15)`). I don't think they admitted people under 80 because that's illegal. But maybe that was a later law. I haven't read the book yet. Apparently, military experience for them seems to make them worse off. https://eric.ed.gov/?id=ED366751

Right, 10th is 80, but the article is contradictory on this. Also, I find it hard to imagine the old rules excluded almost 1/3 of ppl

"One time"?

Yes, one time for IQ, as far as I know, but they did do it accidentally too on another occasion. https://pdfs.semanticscholar.org/eafe/8a64ce8f18398798e3fcd9e459239439120a.pdf …

Might be done. Presumably a lot of Blacks were among the less able, so this would have increased the Black%, thus giving a racial element to the story that the media can use.

Real opposition for he war was an upper-class , highly educated thing. It did differ between ethnic groups, but not the way you think.

No. I'd say it was a mixture of people being decreasingly willing to fight the Cold War and the feeling Vietnam itself wasn't worth it. More the first than the second.

Enlightening. I hadn't heard the expression "McNamara's Morons" before. (Can't imagine why.)
