✦ Synopsis

Abstract

We study the dynamics of public opinion in a model where 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, 3, 87–98; Weisbuch et al., Complexity 2002, 7, 55–63) and establish several new results regarding the patterns of opinions in the asymptotic state and the cluster formation time. © 2009 Wiley Periodicals, Inc.
