ABSTRACT
The spread of rumors in various complex network structures is discussed based on agent modeling in this paper. In addition to infection rate, cure rate and immune rate adopted in the epidemic model, we specially consider the influence of psychological bandwagon effects on rumor spreading. According to the state differences among network individuals, there are three different bandwagon effects: negative bandwagon effect, conscious bandwagon effect and positive bandwagon effect. The results show that the negative bandwagon effect will promote the spread of rumors, while the conscious bandwagon effect will restrain the rumor spreading to a certain extent in the regular network. However, the most important one is the positive bandwagon effect. When the recovered population reaches a certain proportion, the positive bandwagon effect can greatly inhibit the rumor spreading. And the inhibition effect increases with the increase of network heterogeneity. Especially in the scale-free network, the spread of rumors is completely inhibited by the positive bandwagon effect in spite of the initial state of infection.
