People who go for more education are generally higher in IQ in the first place. You can’t raise IQ effectively just by educating people!
Anyway, even if you are not convinced that there is such a thing as native intelligence, then let’s consider culture. The Moslem culture must be pretty terrible to come up with results like these. I think that is the case.
I have met some rather intelligent Moslems. One, in particular, was also a very likeable and tolerant person. Some of the others were paranoid creeps. People differ.
That's just not true. In fact, you can raise your IQ dramatically just by taking a lot of IQ tests. IQ is a notoriously poor measure of intelligence, not that the idea of innate intelligence has much validity to begin with.

I don't think that there is a "Muslim culture" -- how can you possibly compare places as disparate as Nigeria and Indonesia? I do think that most countries in the Islamic world have insufficient education systems, insufficiently diversified economies, and I'd agree with you that some Islamic cultures place too little emphasis on secular education. There are also places like Pakistan, where a relatively small elite places an enormous value on education, but where formalized education of any kind is essentially unavailable to a majority of the population.
