Social Networks and “Happiness Clusters”
It turns out that happiness really is contagious. Need proof? Nicholas Christakis and James Folwer recently published a paper in the British Medical Journal, suggesting that offline social networks have “happy” and “unhappy” clusters. In that study, they found that a person's happiness is related to the happiness of their friends, their friends' friends, and their friends' friends' friends… in other words, up to 3 degrees of separation. In addition, they also found that happy people were more likely to be at the center of their offline social networks, and that each additional happy friend increases your chance of being happy by about 9%. So what about online social networks?
