Not all the abilities measured by IQ are that important to education; see the last two sentences in this comment. Calculations like yours would underestimate the ideal number of women and Jews in academia, and for all I know (admittedly little) that may also apply to African-Americans.
My measure is a little crude; it uses IQ scores without dividing them into fluid/crystallized or verbal/nonverbal and that does have a cost in terms of accuracy. Unfortunately I don't have the time or energy to do much better than a back-of-the-envelope calculation, not to mention my access to census data blows now that the Federal Government is shut down. This is part of why I didn't bother looking at Asian-White or Male-Female differences where the numbers are smaller and the breakdown of scores is messier.
But at the same time; a 1sd difference (either the -1 for Black Americans or the +1 for Ashkenazi Jews) in a highly g-loaded test is such a heavy finger on the scale that I can't imagine how my numbers would be off by the order of magnitude required to call the modern proportions "reasonable."

Sure, I didn't mean that modern proportions are reasonable; mine was just a nitpick.
People want to tell everything instead of telling the best 15 words. They want to learn everything instead of the best 15 words. In this thread, instead post the best 15-words from a book you've read recently (or anything else). It has to stand on its own. It's not a summary, the whole value needs to be contained in those words.
I'll start in the comments below.
(Voted by the Schelling study group as the best exercise of the meeting.)
