Research on the spread of health-centered behavior describes how the structure of social networks can influence how behaviors travel through a population. These figures show experimentally manipulated on-line social networks. The first community (left) has a clustered network structure, while the second one is a more “random” casual contact network. Node colors indicate people who adopted a behavior (blue) and those who did not (white), with lighted links showing the active pathways of communication. The clustered networks spread the behavior to more people than the casual contact networks. Image: Damon Centola (via Better health through social networking
