Partly agree to the "caste" basis of Indian IQ, but on the other hand, need more calibration against actual environmental factors. Even within say NIB/SIB, comparisons should take into account the proportion among these castes who show high IQ, i.e., the frequency distribution within the caste. Further, I suspect there is a very strong correlation with early intellectual stimulus within these castes among certain families or clans.
Since I teach maths at the university/post-grad level in a system where there is no selection exam pre-uni filtering, I have not been able to see cases where, environmental stimulus and gentics could not be separated for a proper experimental study. I have found that a certain level of maths cannot be drilled into someone even from B caste groups. There appears to be a threshold which can be crossed by non B, nonKhatri cases, and which B/Khatri do not appear to cross as a rule. I have had PhD students showing that extra spark who come from non-B/K background, and above 140 seems to be random.
My parents were advised to treat me as a 6-1/2 when I was 2. But parents were sane enough to get me into school at normal ages. Later tests admin through school showed close to a double "ratio". And I usually studied texts of much higher levels and finished school texts within a couple of months. This appeared to be inherited, both from paternal and maternal lines. But they do not belong to the same "gotra", or originally from the same region. Each had intermarried closely within a restricted class of family lines, on an average around 3 trees. My parents were the first such "cross-clan" marriage.
A lady I know closely, comes from Russian father, German mother - is an exceptionally talented mathematician. Scores around 160. Her sister is 125. Probably the source is the father, but then it did not pass on to all siblings. The family originally was displaced a lot due to the revolution and wars, and suffered horribly because the granddad was in the "white army". So environmental factors had been highly negative.
