The relationships between the domain experts who more often have higher IQ and social motivators who have more developed social and emotional intellect (they have higher EQ) also have different aspects. One of the aspects is that domain experts systematically, constantly lose to the social motivators on different levels of the historical development.
There are the interesting ideas of the evolutionist, paleo-neurologist and the doctor of the biological sciences, professor, and the head of the nerve system development labouratory of the Institute of the Human Morphology of the Russian Academy of Medical Science Sergey Vyacheslavovich Saveliev concerning this question. In his opinion the only advantage of human being over the other mammals is our intellect. Intellect developed with the development of the ability of a person to get food and create the means of labour.
Speech and communication emerged as the need to optimize their actions during the hunt and collective labour. However, it began to be used for fraud. It does not necessarily suggest some sort of domain activity and therefore it started the independent evolution. Speech is energetically favorable.
Anyone who could lie so that everyone believed them won in the struggle for females, for food, for the status in the pack, for dominance. Yet the development of speech has no direct connection with the increase in brain size. As it is known, microcephals have lesser brain than chimpanzees, but they speak well enough. According to S. Saveliev at the time of social selection, namely 10 million years ago, at the moment of the emergence of consciousness by primates they stood the process of fighting for females, food and dominance in the pack through social mechanisms. This led to the fact that while combining the individuals began to force out the objectionable from the pack. Such were not only the most aggressive. Such were also cleverer in domain activity, but less successful in the social one.
The averaged type in pack better surrendered to social management. Persons with the more developed domain intellect are more prone to individual activities. They are difficult to control socially, by surroundings, elders, leaders. And how can the leader in the pack allow the presence of those who are not inclined to obey him? If you let even one such character into the pack, then second, third, you can quickly lose power. Domain experts are always dangerous for those with advanced social intelligence. Therefore those who did not yield management on their part were expelled from the pack by the first opportunity.
