"In platforms we trust: the effect of social trust on the prevalence of misinformation on social networks "

Abstract: We model the effect of social mistrust on the distribution of misinformation on a platform. A platform facilitates the creation of a homophilic network which contains users, who more likely to connect with others with whom they share a level of social trust and social similarities, and information sources, with low social trust users being more likely to follow countermedia sources. Users interact with each another and information sources, changing their opinion with some probability that is higher for . When social similarities are relatively more important in determining network structure, high social trust agents communicate more with low social trust agents, leading to misinformation spreading more freely than in networks in which there an echo chamber such that agents of different worldviews are more segregated.
