A Multi-Agent Model of Opinion Formation with Group Polarization
This paper studies the opinion dynamics with group polarization.We say a process of opinion formation is polarizing if the final opinions after group discussion are more divergent than individuals initial opinions.To capture this phenomenon,we develop a multi-agent model of opinion formation in which each agent forms her opinion according to all arguments available to her,and during interacting with other agents,she assimilates the arguments of neighbors in a biased manner which can be represented by a modified Polyas Urn process.We find that biased assimilation of arguments can result in group polarization effectively,especially under the condition when the agents are relatively isolated in the network.
