The evolution of pluralistic ignorance
Alessandra F. Lütz, Lucas Wardil
Pluralistic ignorance is a social-psychological phenomenon that occurs when individuals privately hold beliefs that differ from perceived group norms. Traditional models, based on…
Invasion of optimal social contracts
Alessandra F. Lütz, Marco Antonio Amaral, Ian Braga +1
The Stag-hunt game is a prototype for social contracts. Adopting a new and better social contract is usually challenging because the current one is already widely adopted and stabl…
On the synchronization of coupled random walks and applications to social systems
Ricardo Simão, Lucas Wardil
Some political strategies to win elections over the last years were based heavily on fomenting general distrust in information institutions and favoring distrustful sources. The mi…
Acculturation and the evolution of cooperation in spatial public goods games
Alessandra F. Lütz, Marco Antonio Amaral, Lucas Wardil
Cooperation is one of the foundations of human society. Many solutions to cooperation problems have been developed and culturally transmitted across generations. Because immigratio…
Moderate immigration may promote a peak of cooperation among natives
Alessandra Friedrich Lütz, Marco Antonio Amaral, Lucas Wardil
In a world of hardening borders, nations may deprive themselves of enjoying the benefits of cooperative immigrants. Here, we analyze the effect of efficient cooperative immigrants…
Social dilemma in traffic with heterogeneous drivers
Ricardo Simão, Lucas Wardil
There is a tragedy of the traffic analogous to the tragedy of the commons that can be caused by overtaking. We analyze the effect of overtaking in a minimal model of vehicular traf…
Cooperation in public goods games: stay, but not for too long
Lucas Wardil, Marco A. Amaral
Cooperation in repeated public goods game is hardly achieved, unless contingent behavior is present. Surely, if mechanisms promoting positive assortment between cooperators are pre…
Role-separating ordering in social dilemmas controlled by topological frustration
Marco A. Amaral, Matjaz Perc, Lucas Wardil +3
"Three is a crowd" is an old proverb that applies as much to social interactions, as it does to frustrated configurations in statistical physics models. Accordingly, social relatio…
Stochastic win-stay-lose-shift strategy with dynamic aspirations in evolutionary social dilemmas
Marco A. Amaral, Lucas Wardil, Matjaz Perc +1
In times of plenty expectations rise, just as in times of crisis they fall. This can be mathematically described as a Win-Stay-Lose-Shift strategy with dynamic aspiration levels, w…
Evolutionary mixed games in structured populations: Cooperation and the benefits of heterogeneity
Marco A. Amaral, Lucas Wardil, Matjaz Perc +1
Evolutionary games on networks traditionally involve the same game at each interaction. Here we depart from this assumption by considering mixed games, where the game played at eac…
Cooperation in two-dimensional mixed-games
Marco A. Amaral, Jafferson K. L. da Silva, Lucas Wardil
Evolutionary game theory is a common framework to study the evolution of cooperation, where it is usually assumed that the same game is played in all interactions. Here, we investi…
Reactive Strategies: The Establishment of Cooperation
Elton J. S. Júnior, Lucas Wardil, Jafferson K. L. da Silva
Cooperation is usually represented as a Prisoner's Dilemma game. Although individual self-interest may not favour cooperation, cooperation can evolve if, for example, players inter…
Distinguishing the opponents in the prisoner dilemma in well-mixed populations
Lucas Wardil, Jafferson K. L. da Silva
Here we study the effects of adopting different strategies against different opponent instead of adopting the same strategy against all of them in the prisoner dilemma structured i…
