SYOF: Symposium Dynamics of Opinion Formation – From Quorum Sensing to Polarization

SYOF 1: Dynamics of Opinion Formation – From Quorum Sensing to Polarization

Montag, 27. März 2023, 09:30–12:15, HSZ 01

Quorum sensing is a widespread biological mechanism through which cells can exchange information and achieve a consensus state – hence a pre-social opinion formation process. In societies, opinion formation is a complex dynamical process that can, depending on the voting system and social interactions, lead to polarized societies or multi-parties systems. This symposium focuses on the dynamical processes underlying this opinion formation, the influence of the underlying topology of the opinion space (binary/Ising, Potts, continuous, higher-dimensional) and the resulting phase transitions.
