This article got me thinking, nay, fuming. And this one, even more so.
Why is India's average IQ 81, and that of China 100? Is that why India is growing slower than China? It seems politically incorrect, racist but why is it impossible?
Or is it because, well, India is poorer, so Indian children are more mal-nourished, so their brains don't develop? Is there a poverty bias in IQ tests? After all, Latinos consistently test lower in IQ than Caucasians in the US - and they're poorer. Are they poorer because they have lower IQs, or is it the other way around? Is there also a language gap when it comes to the IQ tests? Were the IQ tests in India taken in English, a non native tongue to most Indians, and taken in Chinese in China - considering that English is less widespread in China, so it is conventional to do nothing in English?
And what of India? Are the richer people smarter than the poorer people? Historically, India has had this shame-on-humanity-caste-system. Did it have anything to do with IQ?
And now with this reputation for smarts than Indian Americans are building in the US ... what does that mean for India? With all the "outliers" drifting towards greener pastures in the US of A, are we leaving India a dumber place than before?
My two cents, finally: The study is not peer reviewed. It is a book. Books are not peer reviewed. It is pure junk, and more rigorous studies need to be performed to be convincing. Averaging some 10 tests in Shanghai and arbitrarily subtracting 6 will not make good IQ measurement.
While it might be possible that reality is not politically correct, I just don't think we have the information to call it yet.
