Conformity-Driven Agents Support Ordered Phases in the Spatial Public Goods Game
TL;DR: In this article, the authors investigate the spatial public goods game in the presence of fitness-driven and conformity-driven agents, and find that conformism generally fosters ordered cooperative phases and may also lead to bistable behaviors.

Abstract: We investigate the spatial Public Goods Game in the presence of fitness-driven and conformity-driven agents. This framework usually considers only the former type of agents, i.e., agents that tend to imitate the strategy of their fittest neighbors. However, whenever we study social systems, the evolution of a population might be affected also by social behaviors as conformism, stubbornness, altruism, and selfishness. Although the term evolution can assume different meanings depending on the considered domain, here it corresponds to the set of processes that lead a system towards an equilibrium or a steady-state. We map fitness to the agents' payoff so that richer agents are those most imitated by fitness-driven agents, while conformity-driven agents tend to imitate the strategy assumed by the majority of their neighbors. Numerical simulations aim to identify the nature of the transition, on varying the amount of the relative density of conformity-driven agents in the population, and to study the nature of related equilibria. Remarkably, we find that conformism generally fosters ordered cooperative phases and may also lead to bistable behaviors.

Regimes of Expectations: An Active Inference Model of Social Conformity and Human Decision Making
Axel Constant,Axel Constant,Axel Constant,Maxwell J. D. Ramstead,Samuel P. L. Veissière,Karl J. Friston +5 more
TL;DR: The computational construct of ‘deontic value’ is introduced – based on active inference and Markov decision processes – to formalize conceptions of social conformity and human decision-making and enables learning of habitual behavior over neurodevelopmental and transgenerational timescales.
An epidemiological model with voluntary quarantine strategies governed by evolutionary game dynamics
TL;DR: An epidemiological SIR model is proposed that uses evolutionary game theory for combining in a single process social strategies, individual risk perception, and viral spreading and shows recurrent infection waves, which are usually seen in previous historic epidemic scenarios with voluntary quarantine.

Stability of subsystem solutions in agent-based models
TL;DR: It is shown that a satisfactory answer can only be obtained by means of a complete stability analysis of subsystem solutions, and it is crucial that the competing subsystem solutions are characterised by a proper composition and spatiotemporal structure before the competition starts.
Opinion dynamics with bounded confidence and group pressure
TL;DR: The authors proposed a bounded confidence plus group pressure model, in which each individual forms an inner opinion relative to the bound of confidence and expresses an opinion, taking group pressure into consideration, and theoretically demonstrate that a group with all individuals facing group pressure can reach consensus in finite time.

Competition and partnership between conformity and payoff-based imitations in social dilemmas
Attila Szolnoki,Xiaojie Chen +1 more
TL;DR: In this article, the authors assume that both payoff-based and conformity-based learning methods are present and compete for space within the framework of a coevolutionary model, and they reveal that the presence of a payoff-driven strategy learning method becomes exclusive for high sucker's payoff and/or high temptation values that represent a snowdrift game dilemma situation.

Five Rules for the Evolution of Cooperation
TL;DR: Five mechanisms for the evolution of cooperation are discussed: kin selection, direct reciprocity, indirect reciprocities, network reciprocation, group selection, and group selection.
Statistical physics of social dynamics
TL;DR: In this article, a wide list of topics ranging from opinion and cultural and language dynamics to crowd behavior, hierarchy formation, human dynamics, and social spreading are reviewed and connections between these problems and other, more traditional, topics of statistical physics are highlighted.

Evolutionary games and spatial chaos
Michael A. Nowak,Robert M. May +1 more
TL;DR: In this article, the authors explore the consequences of placing players in a two-dimensional spatial array: in each round, every individual 'plays the game' with the immediate neighbours; after this, each site is occupied either by its original owner or by one of the neighbours, depending on who scores the highest total in that round; and so to the next round of the game.

Evolutionary dynamics of group interactions on structured populations: a review.
TL;DR: The review particularly highlights that the study of the dynamics of group interactions, like several other important equilibrium and non-equilibrium dynamical processes in biological, economical and social sciences, benefits from the synergy between statistical physics, network science and evolutionary game theory.
