The Real Indian IQ

[G.Subramaniam]

Previously I had written of a South Indian IQ generic advantage. The reality is more Nuanced



The Indian IQ seems to be SIB > Khatri, Sindhi, Jain, Guj-bania > NIB > NI bania > SI-bania



And at the lower ends, SI-IQ is higher than NI-IQ due to more disfunction in NI





SIB, NIB, NI-bania, Khatri etc are Y-DNA = R1A ( Aryan gene )



Non-Brahmin SI = L1



OBC-NI = H1



R1A > L1 > H1



Both in north and south India, R1A is a minority.



SI is dominated by L1 and NI is dominated by H1,

My guess is L1 > > H1, which explains the disfunctionality of NI



Also, L1 mostly marry their 1st cousins and this has a 8 IQ point hit, and hurts them in comparison with R1A



The reason that dravidian castes , esp merchants vastly underperform their NI equiv is 1st cousin marriages which cost 8 IQ





My guess is that SIB-IQ is vastly superior to NIB-IQ due to inbreeding.

NIB marry at 7th cousin on paternal side and 3rd cousin on maternal side, and IQ genes get diluted



Whereas on average SIB marry their 2nd cousin. And at the 2nd cousin level there is no IQ hit of 1st cousin marriage, and IQ genes get concentrated, at the cost of being less physically robust. They probably should move to 3rd cousin levels to improve health without IQ hit and definitely move from sub-caste to jati to bring in fresh blood
