According to anthropologists and the Dunbar number is impossible to maintain stable social relationship with more than 150 people, according to this theory, this issue limit is related to the size of our brain neorocórtex its processing capacity.
I think the theory is attractive to make the complex simple and quantify somewhat difficult to determine. But even if I lack knowledge to assess, ensure that the size matters, I remember those theories weighing brains to determine their capacity, and even came to ensure that the brains of the smartest were larger.
Furthermore, and in another context, the virtual networking capabilities allow us to break away the barrier of 150 contacts, making it possible to maintain a much larger number of contacts in diverse communities.
Without wishing to argue on the basis of the theory Dunbar, the differences between the relations “real and virtual” think they are basically the definition and context.
While in the real world and as defined in the SAR, friends are people I feel pure and selfless personal affection, usually reciprocal, which is strengthened by the deal. In many social networking “friend” is one that simply sends you a message: “Will you be my friend?”, You agree and sometimes, sometimes almost immediately asks you something.
Due to the invasion of outsiders, some social network will allow “defrieding” or what is the same block the connection with a person with whom you were attached and which wants to end the “relationship online.”
With the natural need we have to connect and build our social capital, often for professional reasons, it might be wise to re-ask before accepting a new connection: why are you friends?
