“IQ as a proxy for overall race superiority is, in my opinion, Bunk with a capital B. “
I agreed with you up that point, but when blacks are 65-85 average and whites are 105, there is a HUGE difference that translates into the results we see.
But where do you get that whites average 105? The best Ive found is that the whitest countries (like Switzerland, Norway, etc) cluster at 100.
Look into how infant stimulation, early childhood nutrition, and rich social interaction boost IQ.
I don't deny that there's a genetic component to intellectual development, like ANY development. But nurture plays a big role here. When Ireland was dying of famine 170-180 years ago, the British thought the white-as-can-be Irish on a level with apes.
So: hard to explain the "Celtic Tiger" phenomenon.
One salient difference: 90% of the black children of Harlem in 1910 and 1920 --- as recorded by the census --- lived in a household headed by a married mother and father.
Way higher than the figure for white children today. According to the Census Bureau’s 2016 "America's Families and Living Arrangements" report, the number of U.S. children under the age of 18 living with 2 parents, father/mother, is now 78% for whites, 85% for Asians.
And blacks? Just 38% are living with two parents, including 22% who are living with two parents who are both in their first marriage.
Nobody is doing as well as the Harlem Renaissance cohort.
Something to think about.
That's not a statistical sneeze.
