Presumably the people who write the IQ test, based on whatever population sample they use to calibrate it. Is the point that the average IQ in India is 70-80, as opposed to the average in the US? (This could be technically true on an IQ test written in the US, without being meaningful, or it could be actually true because of nutrition or whatever). What data does the number 70-80 actually come from?
Isn’t the average IQ 100 by definition?
Yes—but whose average?
