Center node: "do zealots increase or decrease the polarization in social networks"
  Abstract: Zealots are the nodes in a social network who do not change their opinions under social pressure, and have been considered crucial in the study of opinion dynamics on complex networks. Here we show that whether or not their presence affects the social polarization depends sensitively on their topological characteristics, and on the initial conditions of the dynamics. To this end, we first quantify the amount of polarization when nodes of the network can exists in two opposite states. We then consider two types of initial conditions, and two types of zealot assignments. Using two different random graph models as substrates, we study polarization dynamics as the fraction of zealots is varied for all four combinations. Our results indicate that zealots are effective only when they are chosen uniformly randomly in the network, and the random initial conditions are used. Even when one of these conditions is violated, increasing zealots' fraction does not make any substantial change in the polarization values.
