Opinion Dynamics under Conformity
We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model interact strategically in the discussion such that their stated opinion can differ from their true opinion. The ...
متن کاملOpinion Dynamics and Wisdom under Conformity
We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors’ expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an agent’s social influence on the long-run group opinion is increasing in network centrality and decreasing i...
متن کاملOpinion dynamics under opposition
We study a DeGroot-like opinion dynamics model in which agents may oppose other agents. As an underlying motivation, in our setup, agents want to adjust their opinions to match those of the agents they follow (their ‘ingroup’ or those they trust) and, in addition, they want to adjust their opinions to match the ‘inverse’ of those of the agents they oppose (their ‘outgroup’ or those they distrus...
متن کاملSocial Influences in Opinion Dynamics: the Role of Conformity
We introduce a model to study the effects of social influences in opinion dynamics. In particular, we analyze the voter model, from a socio psychological perspective, by considering the role of conformity. Conformity is a central issue in social psychology as it represents one of people’s behaviors that emerge as result of their interactions. We introduce a voter model where agents, linked in a...
متن کاملMulti-Level Opinion Dynamics under Bounded Confidence
Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a homogeneous confidence level. This paper proposes an extended model for a group of agents with heterogeneous confidence levels. First, a socia...
