wonder if IQ will get concentrated at the top too, i see smart people move to a few cities and marry other people in their profession or a similar profession. Back in the day before social media and such i feel that dating wasn't so selective (He/She needs to have X,Y,Z), so people had more diversity in who they married and this spread the genes around more.

IIRC IQ has lost a lot of validity as a metric. TLDR: it's basically a back-slapping measure of how western-traditional-logic-problem-educated you are, and therefore a great proxy for success in life (because if you had the time to follow logic problems as a kid in a developed society or near proxy thereof, then you probably had good nurture and good resources).

  This isn't true, IQ is one of the most predictive measurements.

    The outcome of the study of IQ was that it was not predictive of success https://nautil.us/your-iq-matters-less-than-you-think-7708/ https://nautil.us/your-iq-matters-less-than-you-think-7708/

  I used IQ in a vague way as a proxy for sustained focus, ability to see patterns, mental energy etc... No one can argue that people that are higher in these traits have a higher chance at being what we consider "intelligent"

  People say this, but there is little research supporting this claim. On the contrary, the past few decades of research has shown that IQ is (1) hereditary, 0.5-0.8 correlation, depending on the study and (2) increasingly important to navigate a modern, complex society. For example, this paper is a pretty good summary: https://www.sciencedirect.com/science/article/abs/pii/S0160289697900143 https://www.sciencedirect.com/science/article/abs/pii/S01602... Here is a good popular science article on the same subject: https://quillette.com/2018/08/25/the-dangers-of-ignoring-cognitive-inequality/ https://quillette.com/2018/08/25/the-dangers-of-ignoring-cog...

Charles Murray predicted that this would happen but the opposite is happening: the standard deviation of IQ is decreasing.
