I assure you I am in good faith, I understand the topic is sensitive, but I don't know what in my comment would suggest I am in bad faith. I think it is likely that there are differences in IQ between the castes, just as there are other physical differences, and that the higher caste would have on average higher IQ since IQ is a decent predictor of social economic success in most contexts. Perhaps people familiar with the Indian education system can chime in about standardized test scores broken down by caste - my recollection from years ago is that there are differences. By segregated reproduction I just mean that most likely mate selection is done within cast, so any difference in IQ between castes is likely to be slow changing as there is little gene exchange between groups. Something similar happens in US society where there is growing stratification along IQ lines.

If your primary evidence is results-based, why do you assume it's genetics instead of situational? My assumption would be that higher caste students have more opportunities for proper nutrition, education, etc. Looking at babies adopted into another caste, or people marrying across castes, would help shed some light. But it doesn't seem reasonable that 5k years of caste systems would have such an impact on IQ.

50-100 years ago there were huge differences between men and women's test scores, and many speculated that it was due to genetic differences. Fast forward to today where women get equivalent education (at least here in the UK), and those differences have disappeared with women actually doing slightly better than men on average. There's a very high chance that it's not genetic.
