But it still does not answer the questions I have asked:
Again, I ask, who carried out national IQ tests in Bangladesh? When was it carried out?
If no tests were carried out, you can not claim that Bangladesh's national IQ is X, Y or Z or any number. You have to carry out extensive tests over different period across the country to claim that you have some sort of dataset to work with.
You need to consult the various books on this topic, all have references to the empirical evidence. IQ is a very old concept, and globally tests have been done since the 1930's. One pattern is clear: IQ is positively correlated with a societies standard of living, and contribution to the arts and sciences. Unless one's nation is gifted with resource.
You can deny the evidence via semantics, but by simple observation the nations that are building and designing your cars, engines, computers have a greater emphasis on education and top the IQ charts.
There are also Bengali people in India. Tests have been carried out on various Indian states. Please consult google.
Also you may be surprised to know IQ is inversely correlated with Religiosity according to studies.
Here is a wiki article with references.
Religiosity and intelligence - Wikipedia, the free encyclopedia
Well, we as individuals are not in a position to carry out those IQ tests but we can estimate. And by estimation we can conclude that a country in which children has healthy and ample upbringing + early education will have higher IQ on average than a nation in which such conditions are unavailable.
Well that is up to speculation. The chicken and egg argument resurfaces. Are these societies in their current state due to lack of a higher average IQ or is their average IQ the effect of their current living conditions.
As a note intelligent societies are generally better are group work. The world witnessed how the Japanese handled their recent disaster, in comparison to Haiti, which today still lays filled with debris.
Bangladesh has a lot of malnutrition, just like other South Asian countries, among the poor masses. When these people get proper nutrition and education, like first world countries, then we can compare.
What I wonder about is why people of European origin being so intelligent and high IQ, trashed the whole planet with chemical pollution, greenhouse gas and radio-active waste? Who is going to clean it up? We the low IQ Muslims did not do it.
Why the food supply in USA is so full of chemical, hormones etc.? Why do so many of these high IQ people eat this garbage and become obese?
Also I wonder why people of European origin are helping China and India who are big nations of billion plus population and eventually will kick the behind of Western countries? Why commit suicide or at least shoot at your own foot? Is it because of the super smart 1% with significant Ashkenazi element in it and the greed for money and power that goes with being in the 1%? Lets say its because of the super smart Zionists and their greed, when the West goes down under Chinese and Indian Hindutva boot, who will protect Israel? What is the guarantee that India will care about Israel and Zionist concern then and not consider it a liability, when they will have nothing to gain from this group?
you are confusing intelligence with morality.
