when the subjects do not trust each other and change their opinions to the opposite ones (**Figures 3**–**5b** and **7**–**9b**), the number of subjects in states S3 and S4 is similar, irrespective of their initial state.

The results obtained using the suggested models agree with the results presented in Refs. [4, 5, 30]. These works consider the information diffusion, which is an individual case of IPI diffusion in social networks. As opposed to Refs. [4, 5, 30, 39, 40], the suggested model is not based on the probabilistic characteristics of the subjects of the social network but takes into account the social and psychological parameters of the subjects and their psychological state during IPI diffusion in social networks.
