The median IQ for “Indians” has been notoriously difficult to pin down, largely because “Indian” is a fictitious race (and “India” is a fictitious country), but they exist today. So here we are, looking at the IQs of Indians in India, the UK and the United States.
For the IQs of Indians in India and the UK, I use Richard Lynn’s data, but did as much independent verification as I could, and Lynn’s numbers on Indians, to the extent I could check them, were totally verified in every instance. This was a lot of work, but it’s worth it to have peace of mind that these numbers are probably sound.
Richard Lynn is the only researcher I know of who does comprehensive global IQ estimates – he’s the only show in town for now, and so I mainly use his work as a starting point. These posts aren’t going away, and can be added to and modified.
IQs of Indians in India
The median IQ of Indians in the country of India is 82. The median IQ for the continent of India is 84.
The mean IQ of Indians in the country of India is 82.69, while the mean IQ for the continent of India is 82.87.
In 2009 two regions of India participated in the PISA tests. Their scores on reading, science and math together averaged 336. This translates to an IQ of 76, lower than all of the studies shown here.
IQs of Indians in Britain
The data from 2009 is sharply at odds with the older data. It comes from a test of schoolchildren using the “Cognitive Assessment Test”. The pre-2009 scores show an average of 90.42, while the results from the 2009 CAT scores is 95.17.
One can give a median number, but I don’t think it would be meaningful given the sharp jump. I’ll hedge my bets and estimate the IQs of Indians (from the subcontinent of India) living in the UK to be 93.
Indians in the United States
For Indians in the United States, I only know of two sources for estimates. One is some unpublished SAT data from 1990, which gives Indian SAT test takers an average score of 1029, which translates to an IQ of 110.84 compared to a white SAT of 934 which translates to an IQ of 103.96.
If the white IQ is set to 100 in this sample, then the Indian IQ would be 106.62
The other comes from a Forbes article which estimates the IQ of Indian children of 112 based on a backwards digit-span test.
I don’t have a good estimate, but I would guess that the average Indian IQ in the US is 106, just rounding down from the SAT number because they probably do more SAT test prep than whites.
As I said before, “Indian” IQ is very difficult to get a firm grasp on, and it appears that “Indian” probably has several IQ medians because in reality it’s multiple “races”, or at least genetically identifiable groups with their own median IQs.
