Echo chambers and viral misinformation: Modeling fake news as complex contagion
Fig 3
Virality and opinion polarization.
In these graphs, we look V(θc, Pn, Po) (i.e. at the critical threshold level) for each level of Po (opinion polarization) (note: since θc varies with Po, the lines in the graphs cannot be compared with regard to the absolute level of virality.) The different lines denote different level of opinion polarization (Po). The upper graph shows the case (when the echo chamber is polarized), and the lower the control (when opinion polarization is assigned to random nodes in the network.) As can be seen, in the case, Po (the level of opinion polarization) affects , i.e. at what level of network polarization that virality peaks. In the control case, there is no such effect.
