Ukweli,
If I read you correct, then you are stating to us that "our lower IQ" points is the cause of "ndivyo tulivyo"!
In what terms or criteria of the lower IQ makes us to be "ndivyo tulivyo"? is it on our thinking, life style, hard working, desire to be successful, class room or what?
Low average IQ of the population plays a major role in the political process, commerce, achievements in life, etc. It is easier for politicians to manipulate a population of low average IQ. Africans politicians for example, know this fact very well and use it to their advantage to manipulate and exploit the population. It would be almost impossible for politicians in other parts of the world to get away with what Africans politicians get away with.
Low average IQ also limits the achievements made by society. Modern life in particular rewards higher IQ societies. With low average IQ you are limited in terms of your abilities to tame your environment because your innovation and invention abilities are limited. For example, you will face famine while surrounded by the world's biggest lakes and sitting on top of arable land as it the case in Africa. Australia for instance gets less rain per year than Africa but you never hear them talking about a famine or starvation. Why? Perhaps Australians are innovative enough largely because of their higher IQ to avoid such problems.
So the implications of the low average IQ are vast. If you look closely to most Africa's ills you will find out that they are simply a manifestation of the low average IQ among the population.
