Echo chambers and viral misinformation: Modeling fake news as complex contagion
Fig 5
Illustrates the order in which the node activation occurs in successful cascades, by showing the fraction of echo chamber and non-echo chamber nodes to be activated at each time step. The left graph has no difference in activation threshold between inside and outside the cluster, while the right has Po = 0.2. As can be seen, the cluster is activated the first few steps, while the bulk of the non-cluster nodes are activated later, peaking around step 6 or 7. The runs are averaged over 1000 iterations, Pn = {0.7, 0.75, 0.85}, with θ = 0.27.
