Introductions Science Daily (a press release service) brought a new study by sociologist Gerald Mollenhorst to the attention of the Crawler today, which examines how “the context in which we meet people influences our social network. One of his conclusions: you lose about half of your close network members every seven years.”

His research offers several important findings…

Limited in your choices

Mollenhorst investigated, for example, whether the social context in which contacts are made influences the degree of similarity between partners, friends and acquaintances. It was expected that the influence of social contexts on similarity in relationships would be stronger for weak relationships than for strong ones. After all, you are less fussy about your choice of acquaintances than your choice of partner. In relationships with partners, Mollenhorst indeed found more similarity than in relationships with friends. Yet interestingly, the influence of the social context on similarity did not differ between partners, friends and acquaintances. This reveals how strongly opportunities to meet influence the social composition of personal networks.

With his research Mollenhorst has confirmed that personal networks are not formed solely on the basis of personal choices. These choices are limited by opportunities to meet. Another strong indication for this came from the fact that people often choose friends from a context in which they have previously chosen a friend. Moreover, the extent to which our friends know each other strongly depends on the context in which people meet each other.

Individualism

Many sociologists assume that our society is becoming increasingly individualistic. For example, it is held that we strictly separate work, clubs and friends. Mollenhorst established, however, that public contexts such as work or the neighbourhood and private contexts frequently overlap each other.

Furthermore, Mollenhorst’s research reveals that networks are not shrinking, whereas American research reveals such a decline. Over a period of seven years the average size of personal networks was found to be strikingly stable. However, during the course of seven years we replace many members of our network with other people. Only thirty percent of the discussion partners and practical helpers still held the same position seven years later. Only 48 percent were still part of the network. Therefore value the friends you have. As long as you have them that is.
