Echo chambers and viral misinformation: Modeling fake news as complex contagion
Fig 4
Critical network polarization as a function of opinion polarization.
This graph shows how (the network polarization for which the highest virality is reached) depends on Po (the opinion polarization of the cluster). Comparing to Fig 3, this shows the network and opinion polarization at each point at which virality peaks. As the graph shows, the optimal echo chamber has more external connections and fewer internal connections as Po increases. In the control (dashed line), there is no interaction effect between network and opinion polarization.
