I've wondered about its premise, actually. Anecdotally where I live (the Netherlands) I don't feel that "smarter" people get fewer kids than "dumber" people do.

  Studies [1] have been done, and from what I can see at a cursory look most show a negative correlation, especially for female IQ. I think the disparity between high income to low income counties in the US would show this relatively well.

  Lots of interesting reading here - https://en.wikipedia.org/wiki/Fertility_and_intelligence https://en.wikipedia.org/wiki/Fertility_and_intelligence I believe long-term fertility is largely eugenic, favoring those with desirable genes. Whether or not intelligence is viewed as desirable long-term, or if there is a shift, or short-term course-correction; that's going to take many generations to discern. In the US at least there is a perception that in the short term fertility and intelligence are negatively correlated. This is likely due to them erroneously viewing poverty as a proxy for intelligence, and there is a positive correlation between poverty and birth rate - https://www.statista.com/statistics/241530/birth-rate-by-family-income-in-the-us/ https://www.statista.com/statistics/241530/birth-rate-by-fam...
