IQ in Muslim and Non-Muslim Countries

Another abstract from Mankind Quarterly:
The present research found that the Muslim country mean IQ of 81 is half a standard deviation below the mean IQ of non-Muslim nations and is not related to strength of Muslim culture as defined by the percentage of Muslims in the country. The mean IQ of 84 in Arab countries is not associated with per capita income and is incompatible with the intellectual achievements of the golden age of the Muslim Empire. Possible explanations for this decline include hybridization with sub-Saharan Africans, dysgenic decrease in the more educated Muslims employing birth control as suggested by Meisenberg, the Muslim religion not fostering critical thinking, and the intellectual contributions being both exaggerated and made by non-Muslims.

No it isn't. The intellectual achievements of the "golden age" of the Muslim Empire aren't much -- especially when compared to the West.

An IQ of 84 is about what you would expect from Arab countries if you understand that winters are good for your genes. In fact, it's not just Middle Easterners and North Africans who have IQs in the mid 80s -- Indians do as well:

Even in the Balkans the average IQ is only about 93.

"In my recent review of the research on race differences in intelligence that has been carried out over the last eighty years I have set the British IQ at 100 and shown that other Europeans have the same average IQ, except in the Balkans where it drops to around 93."

Anonymous,

I don't disagree. Note that one of the explanations offered is "the intellectual contributions being both exaggerated and made by non-Muslims."

Yes, I definitely saw that.

Yep, consanguinity: http://www.consang.net/index.php/Global_prevalence

Moreover, just about all the worthwhile contributions during the so-called Golden Age of Islam were made by Persians. Then again, Persians do not seem to be that smart, either.

Auster got Hart to admit how the achievements of pre-modern muslims are incompatible with their currently reported IQ's.

The IQ level of Arabs hasn't declined since the Muslim Empire. Populations that evolve in colder environments have higher IQs. That's why Europeans have an average IQ of 100 and Africans have an average IQ of 70. And that's also why Arabs have an average IQ perfectly intermediate to those two populations (IQ 84): Arabs evolved in an environment that was intermediate to the evironments that Europeans and Africans evolved in.

That's perhaps not too surprising. The intellectual achievements of the golden age of the Muslim empire were a product of a small, cosmopolitan educated elite. You could say the same for India, which also had significant intellectual achievements in history, and still does now and then, although the average IQ for that country is in the mid-80s.

Bullshit: http://en.wikipedia.org/wiki/List_of_iranians

Lynn's only IQ data on Iranians is like what, some decades old study on some elementary school kids?

I remember a while back a post at GNXP looked at international performance on some sort of math olympics competition and Iran really outperformed its economic ranking.

This site would suggest otherwise regarding the lineup concerning global IQ by country. We have to take the sample population into account.

If it were true that winters are good for your genes, there were plenty of other intellectually tasking trials that would have selected for intelligence in many non-cold climates. Such as surviving other humans, ie. wars, which I think the Middle East has been exposed to at a monumental magnitude. In addition, what exactly is the mechanism by which cold weather selects for intelligence. maybe for being fat but intelligence? How so? And if this is the case then why is it that a disproportionate amount of mathematical, linguistic, artistic, and architectural foundations, fundamentals and a great deal of elaboration occurs in countries in the Middle east, India, and North Africa? There was a lot of elaboration by western Europeans after some point but that was more a matter of playing out what logically followed from the already present and much more difficult to develop bodies of knowledge. The countries that had been the birthplace of this knowledge had fallen into turmoil during this time and would have likely done the same work if the case had been otherwise. India, China, Egypt, Iraq, Lebanon, Israel

Meanwhile in all of Western Europe we have dirt mounds and stone henge...

I do not trust the IQ testing implicated. The site mentioned contradicts the results most people seem to be familiar with. I believe the tests were biased or the sample sizes were skewed in a way that produced these results. I'm not saying it was intentional, and maybe not completely wrong, but also clearly not consistent with other results so maybe they are not so solid.

This iq test gave me most accurate score http://iqtestpro.com/ ...which was confirmed later by Mensa.
I think measuring smartest country in nonsense!
