• Authors: Antonio F. Peralta, J\'anos Kert\'esz, Gerardo I\~niguez
• Abstract summary: Opinions shape collective action, playing a role in democratic processes, the evolution of norms, and cultural change. For decades, researchers in the social and natural sciences have tried to describe how shifting individual perspectives and social exchange lead to archetypal states of public opinion like consensus and polarization.

• Abstract: 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 change. For decades, researchers in the social and natural sciences have tried to describe how shifting individual perspectives and social exchange lead to archetypal states of public opinion like consensus and polarization. Here we review some of the many contributions to the field, focusing both on idealized models of opinion dynamics, and attempts at validating them with observational data and controlled sociological experiments. By further closing the gap between models and data, these efforts may help us understand how to face current challenges that require the agreement of large groups of people in complex scenarios, such as economic inequality, climate change, and the ongoing fracture of the sociopolitical landscape.

PRISM contributes (i) wide geographic and demographic participation in human feedback data; (ii) two census-representative samples for understanding collective welfare (UK and US); and (iii) individualised feedback where every rating is linked to a detailed participant profile.

  Growing polarisation in society caught the attention of the scientific community as well as news media. We propose to approach the problem by investigating rhetorical strategies employed by individuals in polarising discussions online. We develop multi-topic and multi-platform corpora with manual annotation of appeals to ethos and pathos, two modes of persuasion in Aristotelian rhetoric.

  We establish that human normativity, that is, individual expression of normative opinions based on beliefs about the population, can lead to population-level polarization. Using a game-theoretic model, we establish that individuals with more extreme opinions will have more extreme rhetoric and higher misperceptions about their outgroup members.

It concludes by putting forth an alternative, sociopolitical paradigm that allows subjective models of the world to govern rationality.

• The drivers of online polarization: fitting models to data [0.0]
  echo chamber effect and opinion polarization may be driven by several factors including human biases in information consumption and personalized recommendations produced by feed algorithms. Until now, studies have mainly used opinion dynamic models to explore the mechanisms behind the emergence of polarization and echo chambers. We provide a method to numerically compare the opinion distributions obtained from simulations with those measured on social media.

Even strong majorities can be forced into silence if a minority acts as a cohesive whole. The proposed framework of social feedback theory highlights the need for sociological theorising to understand the societal-level implications of findings in social and cognitive neuroscience.
