Abstract
We study the dynamics of public opinion in a model in which agents change their opinions as a result of random binary encounters if the opinion difference is below their individual thresholds that evolve over time. We ground these thresholds in a simple individual cost-benefit analysis with linear benefits of diversity and quadratic communication costs. We clarify and deepen the results of earlier continuous-opinion dynamics models (Deffuant et al., Adv Complex Systems 2000 [1]; Weisbuch et al., Complexity 2002 [2]) and establish several new results regarding the patterns of opinions in the asymptotic state and the cluster formation time.
