Increased connectivity due to digitization has led to interaction patterns which enable individuals to broadcast information in ways similar to traditional mass media. Thus, the role of mass media to act as a gatekeeper by disseminating only information that is both relevant and sufficiently proven is weakened. A frequently discussed consequence is the apparent emergence of echo chambers in which misinformation is believed to be true. The dynamics causing their emergence, as well as adaptive policies avoiding social networks dominated by misinformation must be better understood. Therefore, the impact of increasing connectivity on a multiplex network model of continuous opinions is studied in this work.
