Social Networks and the Spread of Behavior

1 Course Unit

This course explores the nature of diffusion through social networks, the ways networks are formed and shaped by social structures, and the role they play in health behavior, public policy, and innovation adoption. Topics include: the theory of social networks; the small world model of network structure; constructing models to represent society; the social bases of the adoption of innovations and the spread of new ideas; the role of social networks in controlling changes in public opinion; the emergence of unexpected fashions, fads, and social movements; and the connection between social network models and the design of public policy interventions. Students will learn how to use the agent-based computational modeling tool "NetLogo", and they will work directly with the models to understand how to test scientific theories. We will examine the basic theory of social networks in offline, face-to-face, networks, as well as the role of online networks in spreading new ideas and behaviors through social media. Long standing debates on the effects of social networks on changing beliefs and behaviors, their impact on social change, and ethical concerns regarding their potential manipulation will be given careful consideration throughout. Students will be taught new skills that will enable them to use and develop their own agent-based models.
