I'll put it to you, Twitter:
Should @ezraklein and I do a podcast together?
Maybe the debate should focus on the scientific common ground that is beyond any serious dispute: there are mean phenotypic IQ differences across human groups, regardless of their origin. They exist in every multi-group society. What should we do about them?

I don't think anyone disagrees with phenotypic IQ differences. The debate is about whether IQ = Intelligence. Does that score limit one's range of possible tasks, or is it proxy for hardware differences. E.g. ML tasks run faster with GPUs, but can be completed with CPUs too

The short, very readable, empirically solid book 'Intelligence: All that matters' by
@StuartJRitchie is a great place to start on such issues. - 1 more reply

We don't yet have good data on the polygenic IQ scores across populations, whether they show structural invariance, and how they relate to ancestry informative markers. In 5-10 years, we will. Til then, genetic influences on group differences are very hard to measure.

One place to start for common scientific ground: the 1996 APA blue-ribbon panel that made a strong consensus statement on IQ research, almost all of which remains valid today: https://www.mensa.ch/sites/default/files/Intelligence_Neisser1996.pdf …

This is the best way to do it. Maybe Sam can invite an expert to fact check the arguments made by either Sam or Ezra.

I'm pretty sure it can be mathematically proven that as population X and environmental factors Y increase, the odds of having any trait Z (income, intelligence, height, weight, etc) be perfectly equal across any given group in the population becomes exponentially small.

I’m curious to learn more about this if you know a good book/research....
