Dynamics of opinions with social biases [PDF]
Automatica, 2019 This paper aims to provide a systemic analysis to social opinion dynamics subject to individual biases. As a generalization of the classical DeGroot social interactions, defined by linearly coupled dynamics of peer opinions that evolve over time, biases add to state-dependent edge weights and therefore lead to highly nonlinear network dynamics ...

Whither Now, Opinion Modelers?
Frontiers in Physics, 2020 The article describes the current status and potential directions of development of agent-based models of social opinion dynamics. Despite extensive effort, the models achieve, at best, only qualitative agreement with social observations.

Opinion dynamics: public and private
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2022 We study here the dynamics of opinion formation in a society where we take into account the internally held beliefs and externally expressed opinions of the individuals, which are not necessarily the same at all times. While these two components can influence one another, their difference, both in dynamics and in the steady state, poses interesting ...

Social Depolarization and Diversity of Opinions—Unified ABM Framework
Entropy, 2023 Most sociophysics opinion dynamics simulations assume that contacts between agents lead to greater similarity of opinions, and that there is a tendency for agents having similar opinions to group together. These mechanisms result, in many types of models,

On opinion dynamics in heterogeneous networks [PDF]
Proceedings of the 2011 American Control Conference, 2011 This paper studies the opinion dynamics model recently introduced by Hegselmann and Krause: each agent in a group maintains a real number describing its opinion; and each agent updates its opinion by averaging all other opinions that are within some given confidence range. The confidence ranges are distinct for each agent.

Dynamics Analysis for the Random Homogeneous Biased Assimilation Model
Mathematics, 2023 This paper studies the evolution of opinions over random social networks subject to individual biases. An agent reviews the opinion of a randomly selected one and then updates its opinion under homogeneous biased assimilation. This study investigates the
