  6. of Harvard and of UC San Diego have produced a series of ground-breaking papers analyzing the spread of various traits in social networks: , , , and most recently, in collaboration with John Cacioppo, . The Christakis-Fowler collaboration has now become , but from a technical perspective, what was special about their work? It turns out that they found a way to distinguish between the three reasons why people who are related in a social network are similar to each other. Homophily is the tendency of people to seek others who are alike. For example, most of us restrict our dates to smokers or non-smokers, mirroring our own behavior. Confounding is the phenomenon of related individuals developing a trait because of a (shared) environmental circumstance. For example, people living right next to a McDonald’s might all gradually become obese. Induction is the process of one individual passing a trait or behavior on to their friends, whether by active encouragement or by setting an example
