Mis- and disinformation in a bounded confidence model
Artificial Intelligence, 2021 Abstract The bounded confidence model has been widely used to formally study groups of agents who are sharing opinions with those in their epistemic neighborhood. We revisit the model with an eye toward studying mis- and disinformation campaigns, which have been much in the news of late.

Polarized Ukraine 2014: opinion and territorial split demonstrated with the bounded confidence XY model, parametrized by Twitter data [PDF]
Royal Society Open Science, 2018 Multiple countries have recently experienced extreme political polarization, which, in some cases, led to escalation of hate crime, violence and political instability.

Network effects in a bounded confidence model
Studies in History and Philosophy of Science Part A, 2022 The bounded confidence model has become a popular tool for studying communities of epistemically interacting agents. The model makes the idealizing assumption that all agents always have access to all other agents' belief states. We draw on resources from network epistemology to do away with this assumption.

Bounded confidence opinion dynamics: A survey
AutomaticaThe paper presents a survey for bounded confidence opinion dynamics. It focuses on systems with time-synchronous interactions between the agents. The paper describes properties and conditions on the different classes of this type of synchronous models which ensure the convergence in finite time or asymptotically of the opinions.

Analysis of Opinion Evolution Based on Hegselmann–Krause Model with Historical Opinion [PDF]
EntropyIn realistic social networks, individuals are influenced not only by current interactions, but also by recent historical opinions, prior experience, and external guidance.

Evacuation by leader-follower model with bounded confidence and predictive mechanisms [PDF]
Archives of Control Sciences, 2021 This paper studies an evacuation problem described by a leader-follower model with bounded confidence under predictive mechanisms. We design a control strategy in such a way that agents are guided by a leader, which follows the evacuation path.

Exploring the formation dynamics of affective polarization by considering coupled feedback
Frontiers in Physics, 2023 Polarization issues are generally subject to ideological and affective polarization. Particularly, affective polarization generally accelerates the polarization process.

An opinion dynamics model based on affinity and social noise
Frontiers in Physics, 2022 Most previous works have studied the evolution of opinions based on the Hegselmann–Krause model, the Deffuant–Weisbuch model, and the Sznajd model. However, the influence of social influence on opinions is discussed less.

Computers, 2023 The opinion dynamics literature argues that the way people perceive social influence depends not only on the opinions of interacting individuals, but also on the individuals’ non-opinion characteristics, such as age, education, gender, or place of ...
