The Flynn effect is now reversing it’s course. Ie, that people are literally getting less intelligent. Literally.
perhaps the combination of things it takes to get to good music is taking this reversing effect and showing how bad it is, like a canary in the coal mine.
About a decade ago I finally decided that the effect that I saw was generalized enough and obvious enough that I was fairly confident that what the future seems to be holding..is a splitting into a definable two - of the human race. The actual beginnings of a homo superior vector vs a homo regressus vector. This, outside of all the other complexities of such an idea in analysis. (very complex mess, obviously, so debating it is difficult, at best). Eg, what does the end of the boomer years say about all of this? good luck measuring that...besides the complexities of coming up with good testable hypothesis and the like.
Re the Flynnn effect..it seems as if Idiocracy actually is on the record, now, as being a real thing at least with respect to the current course of humanity, in the now....
Does our social humane integrity end up painting us into a corner? What is even the question?
