Just a follow-up from yesterday’s post about community: Robin Dunbar also writes about the kinds of friendships we form and the number of friends we typically have.
Don’t start over-analysing this and getting depressed about how many friends you don’t have – it’s not a competition or a test of psychological well-being!
On average, we have five intimate friends, 15 good friends (including the five intimate ones), 50 friends and 150 acquaintances. While it is not altogether clear why our relationships are constrained in this way, one possibility is time. A relationship’s quality seems to depend on how much time we devote to it, and since time is limited, we necessarily have to distribute what time we do have for social engagement unevenly. We focus most of it on our inner core of five intimates. Alternatively, it might just be a memory problem: we have a job keeping track of who’s doing what, and can only really keep serious tabs on the inner core of five.
The point about how difficult (and probably unwise) it is to have a large number of ‘intimate friends’ is not different from what Aristotle says about ‘perfect friendship’ in Book 8 of the Nicomachean Ethics.
But it is natural that such friendships should be infrequent; for such people are rare. Further, such friendship requires time and familiarity; as the proverb says, people cannot know each other till they have ‘eaten salt together’; nor can they admit each other to friendship or be friends till each has been found lovable and been trusted by each. Those who quickly show the marks of friendship to each other wish to be friends, but are not friends unless they both are lovable and know the fact; for a wish for friendship may arise quickly, but friendship does not.
Dunbar then connects the question of friendship with yesterday’s question about the ideal size for a community.
But there is one more serious problem lurking behind all this. In traditional small-scale societies, everyone shares the same 150 friends. This was true even in Europe until well into the 20th century, and probably still is true today of isolated rural communities. You might well fall out with them from time to time, but, like the Hutterites, you are bound together by mutual obligation and densely interwoven relationships. And of these, shared kinship was perhaps the most pervasive and important: offend Jim down the road, and you bring granny down on your back because Jim is her second-cousin-once-removed, and she’s got her own sister, Jim’s grandmother, on to her about it.
In the modern world of economic mobility, this simple balance has upset: we grow up here, go to university there, and move on to several elsewheres in a succession of job moves. The consequence is that our social networks become fragmented and distributed: we end up with small pockets of friends scattered around the country, most of whom don’t know each other and, perhaps more importantly, don’t know the family part of our networks. You can offend Jim, and almost no one will care. And if they do, you can afford to move on and leave that whole subset of friends behind. Networks are no longer self-policing.
Because modern geographical communities no longer have the social coherence they had up until the 1950s, it is perhaps inevitable that people become less willing to remonstrate with miscreants because others are unlikely to back them up. Bearing these factors in mind, is it any wonder that some inner-city communities fall victim to gang violence? Our real problem for the future is how to overcome this social fragmentation by recreating a sense of community in our increasingly urbanised and mobile world.
