Abstract: Great progress has been made in the last few years in understanding the structure and function of human social networks, and the mathematical, biological, psychological, and sociological rules undergirding them. But the question remains about what one might do with this knowledge to intervene in social systems to make them better. I will review two classes of interventions, involving both offline and online networks: those that manipulate connection, and those that manipulate contagion. I will illustrate what can be done using a variety of experiments in settings as diverse as fostering cooperation in networked groups online to fostering vitamin adoption in highland villages in Honduras. By taking account of people's structural embeddedness in social networks, it is possible to intervene in social systems to enhance population-level behavior change, facilitate the flow of information, and change outcomes as diverse as emotions and epidemics
