Africa - at least sub-Saharan Africa and Southern Africa, which I am familiar with, is rather 'emotional'. Emotions rule, not the mind. A 'model' (as in the mentioned experiment) that focused on emotional intelligence may be able to assess and manage the emotions of the individual and groups so as to integrate them into a working framework that would result in the betterment of all the population, and also at the same time fulfill the emotional need. There are 2 very distinct groups in Africa, and all fall into one or other of the groups - the haves and the have-nots. Each have-not wants to be in the have group and each in the have group wants to maintain their place there and fear becoming a have-not. In the colonization of Africa, much development of the local population was missed. The development that was missed was one that the western countries went through in past ages. It is really a development thing - as a group, not as individuals because of course there are many exceptions. Kind of like a child that misses certain steps in development. The way to fix that is to go through that development stage, which in this case is the emotional stage, hence I see EI as being more value than the usual IQ.
It's a bit more complex..

but if a model is to be found, it needs to fit. For example, here, in South Africa, they are trying to focus on education, especially the sciences. Meanwhile, the culture of education has been destroyed as it was one of the means of resistence against "bantu" education. It's now biting them in the arse and they don't know how to get out of the mess because they are applying 'logic' to something that has an emotional content.
