Individuals, families, societies, cultures, civilizations are racial constructs. They must be since race determines neoteny, impulsivity, time preference, median intelligence, and less so personality traits. And because all political orders require norms through institutions possible to follow by the median of the population distribution.
The reason Reich – the leading geneticist at the leading lab with the most data – took pains in his last book to caution a reform of the postwar pseudoscientific attack on sex, class and race differences, was because by mid last decade it was inescapable that differences were large and meaningful. Well before 2000 iq was settled science as a class distribution. By 2000 the blank slate was falsified. By 2012 sex difference (one of my specialties) was settled. And by 2017 race differences settled. Meaning the pseudoscientific attempt at genetic equality was reversed.
As Flynn explained, the Flynn effect was largely the result of suppressing the left tail of the curve – in utero, neonatal and natal nutrition and healthcare. Nutrition can suppress the left tail of the curve (developmental defect) but not improve IQ; and yes, india is one of the civilizations affected by birth defects not caused by the consanguinity of the muslim world as is much of the ‘sun’ belt (30 something-th rank). But all population groups float on the same tide while retaining their marginal differences. The fact that the Flynn effect is reversing in the most developed countries is due to asymmetric class reproduction reversing historical norms combined with immigration from lower IQ populations.
