It's scientific fact that intelligence as measured by any manner of g-factor psychometry has heritability correlates of between 0.4 and 0.5. Furthermore, studies such as the Minnesota transracial adoption study show clearly that these correlates apply within racial groups, having fully negated socioeconomic and parenting factors. We have willfully ignored reality per the ideological dictates of progressivism for the last fifty years.

Feelings and ideology trumping reality may work for a while, but it can't last forever when faced with competition from groups and nations that harbor no such illusions, such as the Chinese, who are investing in their genetic research labs to investigate the genetic origins of intelligence so as to benefit their own population generations hence. We, on the other hand, are too frightened to even talk about such investigations. Much to the detriment of our own future.
