Where did you get this data? As per some statistical analysis the mean IQ is 81 for India, 83 for Afghanistan, 100 for Chinese.. the falacy is huge, whenever they couldn't come with a figure they have averaged on the neighbouring country, so Iran is 84 and India is 81, hence Afghanistan's is 83...they have started with an assumption and factored out by ethnicity...and averaging out by neighbourhoods. They haven't veen started out with a huge population, the sample sizes were something like 150 americans of mixed ethnicity...No wonder they should have measured your IQ in finding the Indian IQ.
