Why people are friendly ?!

Our benevolent instincts are the products of our social nature, and to analyse human society as essentially an association of individuals is not just morally but scientifically wrong, since that kind of analysis doesn't predict our behaviour accurately.

A scientific study showed that height is a hugely attractive characteristic: tall people have more friends, and far more people who want to be their friends. No other single characteristic showed such a marked effect.

By studying not just how people form groups but how they would like to do so if they could choose, the researchers showed very clearly that friendship is a universal human quality.

This is fascinating not just in itself, but also has a certain resonance in the world of religion. This is not because there is anything much in common between the myth systems of hunter-gatherers and those of modern believers. In the modern world it is myth systems rather than shared campfires that mark off different groups. Common stories go together with common interests.
