I have met a person who is product of rape, but this Girl is very bright. Her MCAT percentile was 98.7%. Father/rapist was homeless 8th grade drop out, mother is hairdreser.

Regression to the mean
means a given a 150 IQ guy from a caste with 100 IQ average
His kids will likely have 110 IQ
meaning they will regress 80% towards the mean
For example blacks making over $100k a year will have kids doing at the level of
kids of white welfare trailer people
What is happening is the black guy with 105 IQ, ( bare college pass )
gets due to affirmative action , a cushy 100k job
The black average is 85 in US
The black 100k guy of 105 IQ will have kids at 89 IQ
In the indian case,
due to generations of sub-caste endogamy, the IQ has been homogenised to a large extent
Meaning I guess Indian Standard Deviation is more like 10, not 15
so there is very little regression to the mean
And that is why in the US new immigrant survey,
Indian immigrants score at 112 IQ
In my case, I have seen the IQ effect of my maternal grandfather carrying on for 3 generations without any regression
