This course is designed for Master students interested in the logical analysis of social-informational phenomena, including social networks, the wisdom of crowds, cascades, group polarization, echo chambers, pluralistic ignorance etc. This topic is at the intersection of Logic, Social Epistemology and Network Theory.

We analyze forms of group knowledge, as well as the role of individual beliefs and of belief-aggregation procedures in facilitating or distorting the spread of information through a network of interacting agents. We consider various forms of communication, social influence, disinformation, trolling, and other informational actions that can affect a group's behavior and its ability to track the truth. We focus on examples from the literature and their analysis based on theoretical tools and formal models.
