I grew up indoctrinated by political correctness. Like a large part of citizens in Western countries I was brainwashed: Races do not exist, all are equal. Saying anything different, saying that there are racial differences, is racism, a crime.
Read this, everything you need to know about scientific research about racial differences: RACE, EVOLUTION, and BEHAVIOR: A Life History Perspective, by J.P. Rushton
In school I heard disparaging remarks about Artur Jensen and other “unscientific” “dishonest” “cheating” scientists doing faulty research about race differences.
The Bell Curve by Richard Herrnstein and Charles Murray actually looked fairly convincing to me, but if even President Bill Clinton denounced it, there must be something wrong about it.
There always was some complex theory to explain away the IQ differences:
- different culture
- parental expectation
- mother’s malnourishment
- IQ measurements are racially and culturally biased
My opinion changed when I read about trans-racial adoption studies. That was the last drop that really disproved all these desperate attempts to explain away racial differences in intelligence.
“The best evidence for the genetic basis of race-IQ differences comes from trans-racial adoption studies of Oriental children, Black children, and Mixed-Race children. All these children have been adopted by White parents at an early age and have grown up in middle-class White homes.”
Chart 9 summarizes the results for Oriental children adopted into White middle-class homes.
Korean and Vietnamese babies from poor backgrounds, many of whom were malnourished, were adopted by White American and Belgian families. When they grew up, they excelled in school. The IQs of the adopted Oriental children were 10 or more points higher than the national average for the country they grew up in. Trans-racial adoption does not increase or decrease IQ. The three-way pattern of race differences in IQ remains.”
In plain English: adopted Asian babies grew up to be very bright, adopted black babies grew up to have low intelligence.
