People are physiologically unable to effectively support the communication more than 150 friends

Most people believe that we much smarter and more "advanced" of our ancestors. However, as we would have liked to amuse himself such thoughts, our brain is not very successful in development since the primitive hunters and gatherers.



On average, the primitive tribes consisted of 150 members, so the British anthropologist Robin Dunbar believes that people physiologically and historically unable to effectively maintain contact with a group of people more than 150 ("Dunbar's Number"), a person that applies to labor collectives, and social networking.

The ability to communicate does not depend on personal qualities, says English professor. Dunbar reviewed the many groups of people - from the primitive to the modern office community groups and concluded that the number of members of the group more than 150 people, the team ceases to exist as such. Even if the social network a person more than a thousand friends, he maintains regular contact with only a few, usually no more than the same 150 people. The terms of human communication control part of the brain that Robin Dunbar called "the neocortex." The same department is processed conscious of speech and thought.
