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.

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 ...

Discrepancy in scientific authority and media visibility of climate change scientists and contrarians [PDF]
Nature Communications, 2019 The role of climate change (CC) contrarians is neglected in climate change communication studies. Here the authors used a data-driven approach to identify CC contrarians and CC scientists and found that CC scientists have much higher citation impact than

Unanimity, Coexistence, and Rigidity: Three Sides of Polarization [PDF]
Entropy, 2023 Political polarization is perceived as a threat to democracies. Using the Galam model of opinion dynamics deployed in a five-dimensional parameter space, I show that polarization is the byproduct of an essential hallmark of a vibrant democratic society ...

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 ...

Macroscopic and microscopic perspectives for adoption of technologies in the USA. [PDF]
PLoS ONE, 2020 Adoption of a new technology depends on many factors. Marketing, advertising, social interactions, and personal convictions are relevant features when deciding to adopt, or not, a new technology.

Opinion Dynamics With Mobile Agents: Contrarian Effects by Spatial Correlations [PDF]
Frontiers in Robotics and AI, 2018 We investigate the dynamics of opinion formation in a group of mobile agents with noisy perceptions. Two models are applied, the 2-state Galam opinion dynamics model with contrarians and an urn model of collective decision-making. It is shown that models

Confounding dynamic risk taking propensity with a momentum prognostic strategy: The case of the Columbia Card Task (CCT) [PDF]
Frontiers in Psychology, 2015 Figner, Mackinlay, Wilkening, and Weber (2009) developed the Columbia Card Task (CCT) to measure risk-taking attitudes. This tool consists of two versions: in the COLD version the decision maker needs to state in advance how many cards (out of 32) they ...
