Abstract
Nowadays, hot issues are likely become bipolar or multipolar after heated discussion on the Internet. This article is focused on the study of the polarization phenomenon and establishes a public opinion polarization model with the considerations of individual heterogeneity and dynamic conformity. At first, this article introduces the dynamic changing function of an individual’s conformity tendency to other’s attitudes in the interaction process. It further defines the influential weight between different interactive individuals, and expands the interactive individual from complete homogeneity to initial attitude heterogeneity, and finally, conformity heterogeneity. Then, through simulation experiments, we find that the degree of changing in individual attitude is limited. That is, it is difficult for the individuals who have one directional attitude at the initial time to change into another opposite attitude through interaction. In addition, individuals with low conformity within a certain threshold are more likely to form polarization. Finally, the rationality and effectiveness of the proposed model are verified by the typical case “Mimeng Event”.
Highlights
Internet users who are interested in the same hot issue may have certain similarities, and these netizens who are similar to each other often stimulate each other and deepen each other’s emotional level when discussing online, reaching an extreme value gradually
In the public opinion polarization model proposed in this article, it is considered that the agents who interact directly with agent i are agent i’s strong tie interactors, while the other agents in the same network still have an imperceptible influence on agent i, which is the weak tie relation of agent i
This article proposes the concept of individual dynamic conformity, and presents that with the decrease of the deviation degree of the attitudes of all individuals in the network and the formation of decrease of the deviation degree of the attitudes of all individuals in the network and the formation the mainstream attitude, agent i’s confidence in his own opinions is influenced by the mainstream of the mainstream attitude, agent i’s confidence in his own opinions is influenced by the public opinion, and he is more inclined to accept others’ attitudes, which is expressed in formulas mainstream public opinion, and he is more inclined to accept others’ attitudes, which is expressed
Summary
Internet users who are interested in the same hot issue may have certain similarities, and these netizens who are similar to each other often stimulate each other and deepen each other’s emotional level when discussing online, reaching an extreme value gradually This phenomenon is the polarization of public opinion. The emergence of public opinion polarization can deepen the dissatisfaction of netizens and lead to cyber violence, and may even extend to the offline, escalating to group behaviors, such as sit-ins and parades that are against social stability It is of great theoretical and practical significance to study the mechanism of network polarization. The last section is the conclusions and the prospects for future work
