Since a few years there are major social networks like Twitter or Facebook, and yet they are already part of the everyday life of about 950 million users worldwide.
Who's in, in online.
Maintain contacts seemed never been so easy.
But is this all really new?
Friends, the air travel and expensive calls were far away, can be written by the minute now, or you can meet the same for a chat with them before the domestic laptop. For Lau understood.
The distance between people of different countries and continents has become noticeably smaller. Quite naturally it is today, that young people have friends all over the world. Since skyping with Paul as London, found the photo album of Maya from Indonesia for good and directly or communicated to all followers in passing, that you just get hold of a new online ski equipment. For half of the 19-24 year old Facebook even heard before breakfast good form, but have an average of eight friend requests per month and countless event requests are processed quickly and easily.
A seemingly new phenomenon Facebook, which suddenly brings so many more people close to us than before is, strictly speaking, nothing new. Average 130 to 150 people we count on Facebook to our friends and acquaintances, which is composed of private friends, work colleagues, family, school friends and many more. Many people feel that their personal network has increased by Facebook. It is precisely this idea contradicts the Dunbar number, which indicates the theoretical cognitive limit to the number of people in our personal networks. This in turn all the people are counted, with which one is in a reciprocal relationship and combines its own story.
For the evolutionary biologist Robert Dunbar of the University of Oxford, this figure is an image of high psychological demands, which represents life in a large group to each individual. Their origin has this constant boundary in a statistical relationship with the size of the cerebral cortex. For example, English villages in the eleventh and 18th century some 150 men were strong, and it was a common number for a group of hunters and gatherers in the Stone Age. But also modern examples there. Functional textiles manufacturers Gore-Tex builds on growth a new factory with up to a maximum of 150 collaborations, rather than increase at a factory already existing with the same number of employees. Behind this is the idea of a joint venture, where everyone knows everyone and where one does not need complicated things like guide planes or even name tags.
It seems like Facebook but is not a new guarantee for many friends and acquaintances. Rather, it is that social networks stick to tried and tested structures and, if at all shift, our contacts on a virtual level. Also, the number of our close friends has not changed through social networks. Five to seven is the common number of good friendships, average people maintain. Yet such a magical boundary that aufmogelt us our subconscious. Because from a number of seven objects, people, pictures , menu items or like the brain loses the immediate overview and gets into counting; therefore impractical.
This is the number of friends now, on average, 190 has increased, has more to do with the fact that you accept friends faster than acquaintances that one has lost sight again "unfriended". But who really overview of his friends (and thus who gets his more or less private information and more widespread) comes to the care of his circle of friends not around - just like in real life.
Oh, the gentlemen with 500 or more friends, you can now confidently classify showing off in the category, because: Who still retains for there track?
