Special Issue Information

Dear Colleagues,

Studying social networks is the basis for understanding many complex phenomena in our societies.

When do social networks help the efficiency of economic and social activities, and when do they, instead, slow down the coordination and accruement of welfare? Do social networks provide a general informal answer to problems of integration and coexistence of different cultures, or do they increase polarization and segregation? The theory of complex networks has shown that the networks of human relations have statistical characteristics (as the so called ‘small world’ property) that accelerate the spread of opinions, but what if the behavior itself of people may either reduce this spread or instead incentivize the propagation of fake news? When is it the case that having wrong beliefs about reality does not only harm a single subject and his social neighbors, but may have cascade effects over a non-negligible portion of the overall society? In this respect, is the case of online social networks different from the case of real world acquaintances?

These are some of the questions at the core of this Special Issue.

Polarization in online social networks has gathered a significant amount of attention in the research community and in the public sphere due to stark disagreements with millions of participants on topics surrounding politics, climate, the economy and other areas where an agreement is required. This work investigates into greater depth a type of model that can produce ideological segregation as a result of polarization depending on the strength of homophily and the ability of users to access similar minded individuals. Whether increased access can induce larger amounts of societal separation is important to investigate, and this work sheds further insight into the phenomenon. Center to the hypothesis of homophilic alignments in friendship generation is that of a discussion group or community. These are modeled and the investigation into their effect on the dynamics of polarization is presented. The social implications demonstrate that initial phases of an ideological exchange can result in increased polarization, although a consensus in the long run is expected and that the separation between groups is amplified when groups are constructed with ideological homophilic preferences.
