HOUSE OVERSIGHT 026394 Men tend to find elaborate social relations boring. If there is no pleasure in observing and empathizing with people, one will not have good social cognition. IQ is not the only meaningful difference. Chinese pay an inordinate amount of attention to authority. I suspect historically., the authorities tended to kill them a lot if they did not. Jews tend be intellectually independent and anti-authoritarian, which might make them creative and inventive in ways that are hard to find in Asia. At the moment, I think speed/quality of brain development plus motivational system are the key to understanding both mind and individual differences. Important part of human language might be the result in a motivational need to discover/invent grammatical structure, which as a side effect makes us interested in music. It would mean that Chomsky's life long hypothesis, that people have a special circuit for grammatical language, is wrong. They might be GENERAL learners, just like Gorillas, but with a strong motivational urge to build grammatical structure, which the brain simply invents (there are only a few ways in which a natural language can work). That is much easier to wire into a brain than a specific circuit. i my self believe that african music, westrn music , chinese music are a window into the the structure of those layers. . western rigid, african primitve , chinese nature based, . I belive that synphoic movments best describe your layering, they open with a basic simple melody„ after it is learned, it is repeated and" developed" , inverted, distorted, related, etc. the development stage take a long time. then there is a recapitlaltion of the whole. and its inter and intra actions. . african musci has lots of beats. and little development. - no accident, it mirrors their learning process. Interesting question if music is somehow indicative of genetically defined prefs, but I am not sure. It could be path effects, starting in cul
