Social influence has been an object of interest of social psychology for a long time. More recently, sociophysics and Galam's model provide an explanation of rumors spreading in a population explaining some interesting social phenomena as diffusion of false information. Although Galam's model and its recent formalizations are suitable to describe some social behavior, they take into account populations with homogeneous agents. Some recent contributions consider agents who do not change opinion and in some cases are able to persuade the others. Starting from social psychology studies about the role of specific seat occupation we provide a heterogeneous model in which those holding minority opinions can strategically choose specific social gatherings to exert their influence. We simulate the opinion dynamics comparing situations in which there is the minority to others with homogeneous agents. Our results show how the opinion dynamics is affected by the presence of such a minority.

Abstract
Social influence has been an object of interest of social psychology for a long time. More recently, sociophysics and Galam's model provide an explanation of rumors spreading in a population explaining some interesting social phenomena as diffusion of false information. Although Galam's model and its recent formalizations are suitable to describe some social behavior, they take into account populations with homogeneous agents. Some recent contributions consider agents who do not change opinion and in some cases are able to persuade the others. Starting from social psychology studies about the role of specific seat occupation we provide a heterogeneous model in which those holding minority opinions can strategically choose specific social gatherings to exert their influence. We simulate the opinion dynamics comparing situations in which there is the minority to others with homogeneous agents. Our results show how the opinion dynamics is affected by the presence of such a minority.
