“Democracy on Social Networks”

Zoé Christoff’s NWO VENI (2020) research project “Democracy on Social Networks” uses formal tools (from logic, formal epistemology, social choice theory, and social network analysis) to model how network structures affect opinion formation and collective decision making.

On February 8 and 9 2024, the Workshop on Formal Models of Social Networks and Democracy will be held in the city center of Groningen. The goal of the workshop is to bring together researchers interested in the impact of (online) social networks on democracy from different backgrounds and perspectives.
