TL;DR
This paper presents a model of continuous opinion dynamics where agents influence each other through binary encounters, highlighting how extremists can lead to generalized extremism and analyzing the complex regime behaviors.
Contribution
It introduces a model incorporating extremists into continuous opinion dynamics and explains the complex regime diagram through meso-scale interaction features.
Findings
Extremists can drive the entire opinion landscape towards extremism.
The regime diagram complexity is explained by initial interaction dynamics.
Binary encounters influence opinion evolution significantly.
Abstract
We here discuss a model of continuous opinion dynamics in which agents adjust continuous opinions as a result of random binary encounters whenever their difference in opinion is below a given threshold. We concentrate on the version of the model in the presence of few extremists which might drive the dynamics to generalised extremism. The intricate regime diagram is explained by a combination of meso-scale features involving the first interaction steps
