Feedback Loops in Opinion Dynamics of Agent-Based Models with Multiplicative Noise [PDF]
Entropy, 2022 We introduce an agent-based model for co-evolving opinions and social dynamics, under the influence of multiplicative noise. In this model, every agent is characterized by a position in a social space and a continuous opinion state variable.

Opinion Dynamics and Unifying Principles: A Global Unifying Frame [PDF]
Entropy, 2022 I review and extend the set of unifying principles that allow comparing all models of opinion dynamics within one single frame. Within the Global Unifying Frame (GUF), any specific update rule chosen to study opinion dynamics for discrete individual ...

A Survey on Nonstrategic Models of Opinion Dynamics
Games, 2020 The paper presents a survey on selected models of opinion dynamics. Both discrete (more precisely, binary) opinion models as well as continuous opinion models are discussed. We focus on frameworks that assume non-Bayesian updating of opinions.

Echo chambers and opinion dynamics explain the occurrence of vaccination hesitancy. [PDF]
R Soc Open Sci, 2022 Vaccination hesitancy is a major obstacle to achieving and maintaining herd immunity. Therefore, public health authorities need to understand the dynamics of an anti-vaccine opinion in the population.

Opinion Dynamics with Higher-Order Bounded Confidence [PDF]
Entropy, 2022 The higher-order interactions in complex systems are gaining attention. Extending the classic bounded confidence model where an agent’s opinion update is the average opinion of its peers, this paper proposes a higher-order version of the bounded ...

A model-based opinion dynamics approach to tackle vaccine hesitancy. [PDF]
Sci Rep, 2022 Uncovering the mechanisms underlying the diffusion of vaccine hesitancy is crucial in fighting epidemic spreading. Toward this ambitious goal, we treat vaccine hesitancy as an opinion, whose diffusion in a social group can be shaped over time by the ...

Opinion dynamics in finance and business: a literature review and research opportunities
Financial Innovation, 2021 Opinion dynamics is an opinion evolution process of a group of agents, where the final opinion distribution tends to three stable states: consensus, polarization, and fragmentation. At present, the opinion dynamics models have been extensively studied in
