Abstract

In this work we introduce the idea of fitness in the context of opinion dynamics. We obtain the hydrodynamic equations for a kinetic model including the attractiveness or strength of each opinion, and we find a conserved quantity which enable us to characterize the consensus opinion. We compare this model with other rules of interaction, and we show interesting differences on the asymptotic behavior. Our results can help to explain how society could reach a consensus on opinions with lower fitness, despite of the fact that better options are available.
