Vox Day feels that it is quite dysgenic, but I think that we kind of see the Grain of Truth thing going on.
The reality is that 70% of white, non-Hispanic (WNH) births each year for the last decade or so are to college educated women. And still more reality is that a majority of WNH births have been to college educated mothers since sometime in the 80s, when they crossed 50%. So for about 30 years now, a majority of white babies are being born to educated white mothers. And by 1960, the percentage was already over 20%.
Now this is a different issue than raw baby count, but even there, white women had about 2 million babies (after minusing 50k or so Hispanic births, this was before they were a separate category) in 1970 (when college educated mothers were around 25% or so of the total) and in 2015, the most current year available, they also had 2 million babies.
People are having fewer children as a population proportion, that is true, sort of. But the raw count of kids has been very stable for decades, with its structure changing. The right wing having a big conversation about what it means that most white kids are born to college-moms would be more useful than asserting that such motherhood is definitely dysgenic. Which is itself an open question. Intelligence flows from mom, so is having bright women make up more of the moms (particularly the married moms) dysgenic? Yeah, yeah “watered down curriculum”, but that means arguing that the ones who can’t complete coursework in even a watered down form are somehow smarter. Which would be a hard sell.
Even among black women, a higher fraction of mothers who get married before the babies come are college educated. That is, college educated black mothers are often married before the babies come and non-college black mothers are at scary 90% or so out of wedlock levels. A majority of black mothers with a BA or greater are married before the kids come.
So we have a larger population with a static baby count and thus a lower birth rate, but the women left who are bothering to have babies, plural are majority college-attending and married. And they have more higher-order births, they have supermajorities of the 3+ births.
One could make an interesting argument that it was mainly the vanguard of college educated women’s daughters who successfully reproduced. And that also has pretty far reaching implications.
