Model of the evolution of opinion propagation under the effect of group pressure

Abstract

For the consideration of the differences in the influence of group pressure on individuals, based on the Hegselmann- Krause model, this paper introduces the concepts of group pressure, individual type and relationship degree. Based on the new individual interaction rules, the model is established to explore the influence of different factors in the model on the opinion evolution process. The model is built based on new individual interaction rules and explores the effect of group pressure and the proportion of different types of groups in the model on the opinion evolution process. The simulation results show that different network models affect the evolutionary process and the speed of convergence, but not the final evolutionary outcome.The proportion of non-conformity groups greatly affects the degree of consensus of the final opinion. True conformity groups contribute to group consensus, while equity conformity groups promote opinion diversity. The convergence time of group expressed opinions is generally shorter than that of private group opinions. The results of the study assist social managers in guiding the opinion dissemination process in a targeted manner according to the characteristics of different types of groups.
