Opinions and consensus in the paradigms-model on different networks — •Yannik Schädler and Stefan Bornholdt — Institute for Theoretical Physics, University of Bremen, Germany

Opinion- and consensus formation in society is an interesting dynamical process, with fashion and paradigm bubbles as an intrinsic feature. Sociophysics models that concentrate on that particular feature have been proposed in recent years [1], [2]. We here study a variant of the paradigms model and study its dynamics on several network topologies. It contains agents with memory that can interact with neighbours, as well as an innovation and a group-pressure mechanism that generates herding-effects. So far this model has been studied mainly on grid-topologies. The motivation here is to include more realistic social network architectures, and to study the influence of topology in this particular model. We study innovation waiting times or innovation rates in different settings. We find that the network topology indeed changes the dynamics: Simulations show that the network structure strongly affects the likelihood of a consensus.
