Social Networks and Happiness by Nicholas A. Christakis & James Fowler ~ Edge.org
We found that social networks have clusters of happy and unhappy people within them that reach out to three degrees of separation. A person's happiness is related to the happiness of their friends, their friends' friends, and their friends' friends' friends--that is, to people well beyond their social horizon. We found that happy people tend to be located in the center of their social networks and to be located in large clusters of other happy people. And we found that each additional happy friend increases a person's probability of being happy by about 9%. For comparison, having an extra $5,000 in income (in 1984 dollars) increased the probability of being happy by about 2%.
Happiness, in short, is not merely a function of personal experience, but also is a property of groups. Emotions are a collective phenomenon.
