Does the structure of your beliefs shape how whole societies polarize?

Irene Ferri, Albert Díaz-Guilera, Hiroki Sayama

May 20, 2026

Most opinion models treat each person as a single yes/no switch, but real people hold networks of beliefs that constrain each other. This model gives each agent an internal belief graph and connects agents through a social network, then asks how internal structure shapes collective polarization. Star-shaped belief networks—where one core belief anchors all others—keep societies resistant to de-polarization at higher social temperatures than ring or clique structures, and mixing agent types produces regime-dependent surprises depending on how strongly neutral stances are weighted.
