Effect of the propaganda (δ) and transfer of benefit (τ) in modelling the dynamics of TNs. We consider a baseline case in which neither of the proposed mechanisms are present (δ = 0 and τ = 0, first row), the case in which only propaganda is used (δ = 0.5 and τ = 0, second row), and the case in which only the transfer of benefit is considered (δ = 0 and τ = 0.5, third row). The combined effects of both mechanisms is shown in the Supplementary Fig. S6. (a,d,g) Each panel shows the stationary distribution of the different roles, similar to Fig. 1a, but for βC = 0 and different values of βH and βS. Filled circles represent relevant configurations displayed. (b,c,e,f,h,i) Dynamics of the model under relevant parametrisations.
