Black males are (extremely) disproportionately responsible for crime, which corresponds to black disproportionality of the lower IQ curve, and the black disproportionality of the faster rate of maturity curve, and black disproportionality of the testosterone curve, and black dominance of the reverse-neoteny curve.
Blacks have shorter gestation periods. Blacks have lower metabolisms useful in heat, but lower industriousness as a consequence, when this factor alone will produce as great a difference in income potential as intelligence. Stereotypes are not only a necessity of temporal and cognitive efficiency, but they are the most accurate measurement in the social sciences because they must survive daily falsification (survival from competition). Because blacks mature earlier, and are more socially dependent for judgement and experience teen status pressure earlier and more deeply, they are disproportionately affected by awareness of lower social, sexual, economic, and political market value – when in proximity to other groups (Diversity is a ‘bad’). Despite the fact that (affect of deeper maturity) have higher self confidence at conflict with signal feedback. Worse, black males are disproportionately from single mother homes. And single mothers produce the majority of children with problems, particularly with children that mature early.
So it is somewhat ‘torturous’ to mix black, muslim, and Hispanic with white, asian, and jewish populations, which creates conflict when what each group needs is homogeneity so that they can develop norms, laws, and institutions that suit their rates and depths of maturity and their vastly different class distributions. The worst crime whites have done was not slavery, which was endemic, it was to copy the soviets and force integration and deprive blacks of their emerging norms and institutions, but also their emerging middle, professional, and upper classes, who ‘defected’ due to the cost of carrying the vast black underclass and laboring class, that cannot compete outside of it’s own demographic.
Africans evolved to survive heat, disease gradient, parasite gradient, many predators, many many human competitors. They have superior physical traits from bones, to sprinting to hearing, to skin. This is because neoteny is dangerous in their ancestral environment wich rewards rapid and deep maturity, and they were not able due to distance from trade routes, able to institute an agrarian empire sufficiently concentrated per square mile to cause upward reproduction of the upper classes due to continuous starvation of the underclasses.
The lower latitudes produce greater ability to expand the upper classes (higher neoteny), and the higher latitudes produce greater abiity to sustain the lower classes (Less neoteny).
Ethnocentrism is always superior for the simple reason that we can produce norms and institutions that suit our group’s distributions without competing for norms and institutions with others that require different norms and institutions.
We use the examples of ashkenazim and sub saharan african as extremes at both ends of the spectrum. But the spectrum of success at shrinking the population below the minimum necessary for self training (105) is available to every group. The question is whether the elites in any group can force this reproductive change. Because by and large that seems very difficult with the development of rifles, that produced military equality offset only by numbers, and prohibited a professional military caste from domesticating the population through agrarian production.
