Dynamic Parameter Calibration Framework for Opinion Dynamics Models [PDF]
Entropy, 2022 In the past decade, various opinion dynamics models have been built to depict the evolutionary mechanism of opinions and use them to predict trends in public opinion.

Asymmetric Contrarians in Opinion Dynamics [PDF]
Entropy, 2019 Asymmetry in contrarian behavior is investigated within the Galam model of opinion dynamics using update groups of size 3 with two competing opinions A and B.

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 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 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.

Ratio-Dependent Contrarian Activation in Opinion Dynamics [PDF]
EntropyI study the impact of mixed contrarians on the opinion dynamics of a heterogenous population with conformists using the Galam Majority Model. Activation of contrarians is a function of the majority/minority ratio in the local groups of discussion ...

Role of Time Scales in the Coupled Epidemic-Opinion Dynamics on Multiplex Networks [PDF]
Entropy, 2022 Modelling the epidemic’s spread on multiplex networks, considering complex human behaviours, has recently gained the attention of many scientists. In this work, we study the interplay between epidemic spreading and opinion dynamics on multiplex networks.

Democratic Thwarting of Majority Rule in Opinion Dynamics: 1. Unavowed Prejudices Versus Contrarians [PDF]
EntropyI study the conditions under which the democratic dynamics of a public debate drives a minority-to-majority transition. A landscape of the opinion dynamics is thus built using the Galam Majority Model (GMM) in a 3-dimensional parameter space for three ...
