Περίληψη
The propagation of fake news and its refutation is modeled, based on Subjective Logic, and simulated in undirected networks, whose nodes have no prior knowledge or opinion or bias towards one of the two opinions, while, when they don’t receive any relevant information, they gradually forget their previous opinion. The main conclusion is that in most networks the first opinion propagated (the fake news) prevails on the majority of persons, while the second opinion (the refutation), if it is propagated many times, has the potential to cause at best a degree of confusion. The results depend on the network’s size. If the network is large the opinion decay is so strong that finally neither opinion prevails. Finally, in small Scale-Free networks, under certain circumstances, the propagation of the second opinion can increase the influence of the first opinion.
