Isn't an IQ of 100 by definition the average IQ of the country studied? What do they define as an IQ of 100 if not the average of their population, what are the tests calibrated on?
Obviously 100 is calibrated to western populations.
I believe IQ has also risen steadily with time in the west. It might have risen an entire standard deviation. It's called Flynn's effect, 3 points per decade.
That can't be explained by pure heritable genetics. Epigenetics possibly, nutrition, better education systems, higher information dissemination.

How could you calibrate a cultrually-specific test like most IQ tests are by comparing with another culture?
I'm also pretty sure that people don't use the same tests across "the West", so that seems dubious to begin with.

That is more easily studied, as you can use the same test across generations and notice trends.
