I don't believe it to be genetic.....it is more a case of Democrats applauding sociopathologies.
It is particulary simple to prove that Democrat's advancing what they consider the 'authentic' subculture, actually a pathological one that injures the group, black Americans:
In their desire to win the votes of the black community, Democrats/Liberals, with no desire to advance the happiness and success of these folks, simply pat them on the head and refuse to describe any pathology as wrong. The result is that there is never a need to better oneself: problems are always other folks'....white folks.....oppression.
Is it possible to induce psychopathology in a subculture????
Clearly the answer is "yes."
Another feature to consider in the heredity vs. environment controversy: females are several times as numerous as males among blacks with high IQs. Witty and Jenkins, "Educational Achievement of a Group of Gifted Negro Children," Journal of Educational Psychology, vol. 25, p. 593. They inherit the same genes, are raised in the same homes and neighborhoods......explanations rest on the culture, the excessively 'macho' roles of males associated with and emphasizing certain sociopathologies.
There is a pathology that certainly holds some individuals back, and it is one that has been encouraged by the Liberals/Democrats.
Yet the most ignorant members of said group refuse to acknowledge this truth, and continue to pay homage to the very individuals that are oppessing them: Democrats.
The only question is, whether the debilitation can be reversed.
