Another part explanation for the NIB - SIB IQ difference
Anti- brahmin Quotas have been in place in old Madras Presidency
for about 4 generations
Those SIBs who survived the quota had to be of a much higher IQ than the pre-quota
Whereas in north India, Mandal is rather recent and with private sector jobs opening up, the selection pressure is a lot less
So, for SIBs even a 1 IQ selection bias per generation could build up to 4 IQ in 4 generations
