A Jury of One: Opinion Formation, Conformity, and Dissent on Juries

The Model and Analysis of Conformity in Opinion Formation

ZHANG LI, LIU YUN School of Electronics and Information Engineering Beijing Jiaotong University Beijing, 100044 China [email protected] Abstract: The formation of public opinion has been focused by many scholars recently; a lot of models have been proposed to verify the process of formation. Many models have noticed that individuals can exchange their opinions and many scholars make their ow...

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 ...

Optimal Jury Design For Homogeneous Juries With Correlated Votes

In a homogeneous jury, in which each vote is correct with the same probability, and each pair of votes correlates with the same correlation coefficient, there exists a correlation-robust voting quota, such that the probability of a correct verdict is independent of the correlation coefficient. For positive correlation, an increase in the correlation coefficient decreases the probability of a co...

Opinion 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...
