Opinion formation in an open system and the spiral of silence

  title={Opinion formation in an open system and the spiral of silence},
  author={Przemyslaw Gawronski and M. Nawojczyk and Krzysztof Kułakowski},
A new model is formulated of the sociological effect of the spiral of silence, introduced by Elisabeth Noelle-Neumann in 1974. The probability that a new opinion is openly expressed decreases with the difference between this new opinion and the perceived opinion of the majority. We also assume that the system is open, i.e. some people enter and some leave during the process of the opinion formation. An influence of a leader is simulated by a comparison of two runs of the simulation, where the…

The dynamics of opinion expression

A model of public opinion expression that identifies social-structural conditions for public opinion predominance of different groups and shows under which circumstances a minority can dominate public discourse is introduced.

Are social bots a real threat? An agent-based model of the spiral of silence to analyse the impact of manipulative actors in social networks

It is shown that, in a highly polarised setting, bot participation by as little as 2–4% of a communication network can be sufficient to tip over the opinion climate in two out of three cases, demonstrating a mechanism by which bots could shape the norms adopted by social media users.

The diamond model of social response within an agent-based approach

This work will present the logic of the diamond model as well as its implications for agent-based modeling, particularly useful in building agent- based models of opinion dynamics.

Hiding opinions by minimizing disclosed information: an obfuscation-based opinion dynamics model

A formal opinion dynamics model is proposed to study the hitherto unexplored effect of obfuscation on public opinion formation based on the recently developed Action-Opinion Inference Model to simulate two cases with different levels of complexity.

Opinion Contagion: What is to be Learnt from a Simulation Model?

The paper introduces a simulation, which was developed by Michael Krassa to model the opinion contagion. Krassa developed his model by using the theory of the spiral of silence that says that the

Zaller-Deffuant model of public opinion

Recent formulation of the Zaller model of mass opinion is generalized to include the interaction between agents. The mechanism of interaction is close to the bounded confidence model. The outcome of

Spiral of Silence

The spiral of silence theory describes the process in which people who perceive their opinion to be in the minority are unwilling to express it due to fear of isolation from society. This article

Phase transitions and hysteresis in a cellular automata-based model of opinion formation

A particular case of a cellular automata-based model of two-state opinion formation in social groups with a strong leader is studied. We consider a 2D Euclidian geometry of “social space” and mutual
