Food riots, revolutions, ethnic violence, urban health, fads and panics arise from collective actions. Complex systems science provides new opportunities to understand these collective behaviors by describing the patterns of behavior of individuals interacting through social networks. Predicting collective action is often easier than that of individuals because of the reduced role of individual choice. The role of individuals in the social context, as well as the role of organizational structures—governments, institutions, and corporations—can also be analyzed.
