      Dramatic decrease in fraction of high-IQ teenagers in past 20 years. Many fewer reach Piaget’s “formal operations”: ability to think systematically. ♻️@DegenRolf, @Black__Dwarf http://www.sciencedirect.com.sci-hub.tw/science/article/pii/S0160289617302787# …pic.twitter.com/wBbEArmVxI

      Focus of the article is different but I do cover quite a bit about (I think much more likely) non-genetic explanation: https://www.informationweek.com/mobile/mobile-devices/3-keys-to-gamification-for-education/d/d-id/1109937 …? (Focus is actually on something hopeful). (Found this thread via @puellavulnerata )

      First of all, the Flynn Effect is SO gigantic that it requires believing that the pre-WW1 intellectual flowering was somehow carried out mostly by mild/moderate learning disabled people (see that article for quick explanation)

      Secondly, if reproductive selection could produce effects that big in 3-5 generations, how did hundreds of years of celibate priests/monks/nuns (chosen largely from the brainy) not turn Latin Christians into drooling idiots compared to Orthodox Christians?

      Because each new member of the religious orders was drafted from the pool of children produced by non-celibate laity?

      i e., intelligence emerges spontaneously from diverse genetic material rather than from inbreeding (which produces retrogrades). And it’s not like 100% of the smart people were removed from the population by orders drafts

      Differs from lower birth rate among high IQ people today how? Point is,If reducing birth rate of the very smart produces dumber population, 20 or so generations of encouraging celibacy among the smartest should have done far more damage than 3-5 of late marriages & birth control

      It doesn’t differ. I reject that explanation for what’s going on now (it anything truly is). Isn’t hard to see how even a 5% leak rate of high-IQ into reproducing population could sustain a steady streak of high-IQ offspring. Something else is happening (if anything).

      People not reaching the highest levels on the Piaget scale in the same numbers as formerly is actually more worrisome than IQ distributions, I think -- because it probably indicates that we're doing something dumb with our very smartest people

      Agreed. And yea I think that’s the case. The education system we have now leaves a lot to be desired (and has been dumbed down considerably over time).

      In my casual experience, practices at schools are a function of IQ of pupils, parents, teachers and oversight.
