      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?

      There's also an enormous amount of quite competent intellectual history documenting how miserably bad the process of defining "smart" in order to calibrate the original IQ tests was...

      ...and the many fixes and reforms since are kludges on a basic process of trying to derive a continuous metric from a ranking, which is just plain shitty method.

      Not to say that we aren't seeing a decline in high-level thinking -- we probably are -- and it probably has several relationships with how we deal with the very smart -- but what's happening in their pants ain't it.

      Don't underestimate the increased efficiency of high-level thinking due to the internet.

          I don’t know what you mean by “increased efficiency of high level thinking”. Having taught logic, rhetoric, and other academic fundamentals for about 25 years off and on I’d guess there was some mild deterioration in those skills after wide availability of the web.

          Oh, the affect on average cognitive performance is sure to be devastating, but intellectual progress has always been driven by only a few thousand individuals, which now have much better access to peers, knowledge and tools.
