Politcal Correctness doesn't want you to learn the truth nor get in touch with real science. Instead the promulgate the same statist, antiwhite, communist propaganda labeled as "humanities" without even the slightest piece of empirical evidence behind it. The fact is that real world scientific evidence lies all with the Racial Realists and none with the silly commies.

Here are some excerpts:

"A three-way pattern of mean differences is also seen in personality, with blacks being the most (and East Asians the least) aggressive, impulsive, dominant and sociable, whereas East Asians are the most cautious (and blacks the least) on average. It is also seen in social organization, with East Asians having higher rates of marital stability, law abidingness, and mental health than whites, and whites having higher rates than blacks.
The apparent evolutionary divergence between the three lineages is not just from ‘‘the neck down.’’ East Asians have the largest skulls, largest brains, and most cortical neurons, whereas blacks have the smallest skulls and brains and the fewest cortical neurons, on average"

"a somewhat less K-oriented  human populations will tend more strongly toward social
relations guided by self-interest, relative physical strength, and a tolerance for interpersonal conflict, with the result that, from a K perspective, they produce cultures with less stable families, less organized institutions, more transgressions of person and property, and therefore higher rates of mental and physical illness."
