Each of these people make 3, calls per year, about 10 a day. The team says that the individual who made the highest number of calls to another person called over 15, times. The team also point out that is a good year to look for Dunbar layers because it predates the widespread use of smartphones and social networks like Facebook. These provide other avenues for social contact that would have made the study much harder.
Dunbar and co mine this data by counting the number of calls that each individual makes to his or her contacts and using clustering algorithms to look for patterns within the results. But the results make for interesting reading. Different clustering methods give slightly different results, but nevertheless, the team says the average cumulative layer turns out to hold 4.
The team also finds some evidence of an extra layer among some people. But interestingly, extroverts, while having more friends, still have a similar number of layers. In total, the study shows good evidence for the existence of the innermost and outermost layers but with some variability for the size of the intermediate layers. Interesting stuff.

Are you ready to give your network a new purpose in life? After reading about Bill Gore, I spent a bit of time reorganizing my network.
To start this process, I made a list of the different areas in which I frequently find myself either working or asked to make a connection. Across my address book, I have nearly 4, contacts. Some, like the University of California, Berkeley, professor Morten Hansen, have pointed out that social media has facilitated more effective collaborations.
Our real-world friends tend to know the same people that we do, but, in the online world, we can expand our networks strategically, leading to better business outcomes. Yet, when researchers tried to determine whether virtual networks increase our strong ties as well as our weak ones the ones that Hansen had focussed on , they found that, for now, the essential Dunbar number, a hundred and fifty, has remained constant. When the Michigan State University researcher Nicole Ellison surveyed a random sample of undergraduates about their Facebook use, she found, while that their median number of Facebook friends was three hundred, they only counted an average of seventy-five as actual friends.
But one of the things that keeps face-to-face friendships strong is the nature of shared experience : you laugh together; you dance together; you gape at the hot-dog eaters on Coney Island together. We do have a social-media equivalent—sharing, liking, knowing that all of your friends have looked at the same cat video on YouTube as you did—but it lacks the synchronicity of shared experience.
With social media, we can easily keep up with the lives and interests of far more than a hundred and fifty people. But without investing the face-to-face time, we lack deeper connections to them, and the time we invest in superficial relationships comes at the expense of more profound ones. We may widen our network to two, three, or four hundred people that we see as friends, not just acquaintances, but keeping up an actual friendship requires resources.
If you garner connections with more people, you end up distributing your fixed amount of social capital more thinly so the average capital per person is lower.
Social networks may be growing our base, and, in the process, reversing that balance. On an even deeper level, there may be a physiological aspect of friendship that virtual connections can never replace.
Over the past few years, Dunbar and his colleagues have been looking at the importance of touch in sparking the sort of neurological and physiological responses that, in turn, lead to bonding and friendship. With a light brush on the shoulder, a pat, or a squeeze of the arm or hand, we can communicate a deeper bond than through speaking alone.
