Our maximum numeral of friends is actually define by the size of our brains . Dunbar ’s number says 150 friends is about the human limit , and that ’s been dead on target throughout history . Can human evolution withstand the insanity of social networking ?
In the 1990s , British anthropologist Robin Dunbar realized that the size of primate social groups increased as the size of it of the primate ’s brain got bigger . peculiar to see whether this correlational statistics could forecast the maximal size of human social group , Dunbar used information from lashings of primate species to calculate that human mathematical group size should top out at about 148 , which is often rounded to 150 . The right-down maximum is a bit higher than that – perhaps as much as 230 – but 150 is the usually cited physique , and with good reason .
This is because Dunbar then examine human social grouping throughout history , and he kept come back to that 150 number . It ’s the issue of mass who exist in ancient Neolithic husbandry villages , the basic unit of measurement size for the armies of both ancient Rome and modern times , and the maximum size of most mobile kin . Now , as Dunbar himself is quick to show out , this does n’t describe every possible societal grouping . Rather , this describes groups that have a very strong incentive to remain together .
A military unit plain does , and so too would bands of nomad and subsistence agriculture communities . The key here is that these are all groups founded on comparatively knowledgeable societal relationships – you do n’t have the opulence of effortless relationships when your very survival is tied to the coherence of the radical . Even when your biography is n’t on the line , multiple field have borne out Dunbar ’s canonic finding that you ca n’t conserve regular liaison with more than about 150 hoi polloi .
But you might see a potential counterargument to this . Is the roadblock really genial , as Dunbar suggests , or is it more a product of circumstance ? The bluff logistics of maintaining even contact with , say , a thousand people might make the labor inconceivable , but that does really intend our minds ca n’t cope with it ? That ’s where new research by Indiana University ’s Bruno Goncalves inscribe the depiction .
He and his enquiry squad studied the social meshwork build up by three million Twitter users over the last four years , which mean looking at a whopping 380 million tweets . Most Twitter users fall into a intimate pattern – they start using the help , then they build up a immense number of friends , and then they get overwhelmed . Once the saturation tip is reached , Goncalves found masses start to root for back on the amount of mass with whom they remain in unconstipated contact .
And just what was this Twitter impregnation period ? Why , somewhere between 100 and 200 people , of course . Even with all the tools of the digital age , people could n’t get past the Dunbar number . It ’s more evidence that our basic social functions – including how many people we can really be friends with – is hardwired into our brains , and it ’s going to take some truly heroic mind hack to get us past that point . Of naturally , I find the approximation of even 150 friends to be quite overwhelming … but then , I am a blogger .
