Opinion dynamics in social networks: From models to data

AF Peralta, J Kertész, G Iñiguez - arXiv preprint arXiv:2201.01322, 2022 - arxiv.org
Opinions are an integral part of how we perceive the world and each other. They shape
collective action, playing a role in democratic processes, the evolution of norms, and cultural …

Effect of algorithmic bias and network structure on coexistence, consensus, and polarization of opinions

AF Peralta, M Neri, J Kertész, G Iñiguez - Physical Review E, 2021 - APS
Individuals of modern societies share ideas and participate in collective processes within a
pervasive, variable, and mostly hidden ecosystem of content filtering technologies that …

Discontinuous phase transitions in the multi-state noisy q-voter model: quenched vs. annealed disorder

B Nowak, B Stoń, K Sznajd-Weron - Scientific Reports, 2021 - nature.com
We introduce a generalized version of the noisy q-voter model, one of the most popular
opinion dynamics models, in which voters can be in one of s≥ 2 states. As in the original …

Consensus, Polarization and Hysteresis in the Three-State Noisy q-Voter Model with Bounded Confidence

M Doniec, A Lipiecki, K Sznajd-Weron - Entropy, 2022 - mdpi.com
In this work, we address the question of the role of the influence of group size on the
emergence of various collective social phenomena, such as consensus, polarization and …

Discontinuous phase transitions in the q-voter model with generalized anticonformity on random graphs

A Abramiuk-Szurlej, A Lipiecki, J Pawłowski… - Scientific Reports, 2021 - nature.com
We study the binary q-voter model with generalized anticonformity on random Erdős–Rényi
graphs. In such a model, two types of social responses, conformity and anticonformity, occur …

A Veritable Zoology of Successive Phase Transitions in the Asymmetric q-Voter Model on Multiplex Networks

A Chmiel, J Sienkiewicz, A Fronczak, P Fronczak - Entropy, 2020 - mdpi.com
We analyze a nonlinear q-voter model with stochastic noise, interpreted in the social context
as independence, on a duplex network. The size of the lobby q (ie, the pressure group) is a …

Composition of the Influence Group in the q-Voter Model and Its Impact on the Dynamics of Opinions

T Weron, P Nyczka, J Szwabiński - Entropy, 2024 - mdpi.com
Despite ample research devoted to the non-linear q-voter model and its extensions, little or
no attention has been paid to the relationship between the composition of the influence …

-voter model with independence on signed random graphs: Homogeneous approximations

A Krawiecki, T Gradowski - Physical Review E, 2024 - APS
The q-voter model with independence is generalized to signed random graphs and studied
by means of Monte Carlo simulations and theoretically using the mean-field approximation …

Threshold model with anticonformity under random sequential updating

B Nowak, M Grabisch, K Sznajd-Weron - Physical Review E, 2022 - APS
We study an asymmetric version of the threshold model of binary decision making with
anticonformity under an asynchronous update mode that mimics continuous time. We …

Pair approximation for the -voter models with quenched disorder on networks

A Jędrzejewski, K Sznajd-Weron - Physical Review E, 2022 - APS
Using two models of opinion dynamics, the q-voter model with independence and the q-
voter model with anticonformity, we discuss how the change of disorder from annealed to …
