Reasons for cooperation and defection in real-world social dilemmas [PDF]

open access: yesJudgment and Decision Making, 2014
Interventions to increase cooperation in social dilemmas depend on understanding decision makers' motivations for cooperation or defection. We examined these in five real-world social dilemmas: situations where private interests are at odds with ...

Introspection dynamics: a simple model of counterfactual learning in asymmetric games

open access: yesNew Journal of Physics, 2022
Social behavior in human and animal populations can be studied as an evolutionary process. Individuals often make decisions between different strategies, and those strategies that yield a fitness advantage tend to spread.

Interplay of Elementary Interactions Causing Social Traps in Evolutionary Games

open access: yesFrontiers in Physics, 2020
In evolutionary games, pair interactions are defined by payoff matrices that can be decomposed into four types of orthogonal elementary games that represent fundamentally different interaction situations.

Cooperative phenotype predicts climate change belief and pro-environmental behaviour

open access: yesScientific Reports, 2022
Understanding the psychological causes of variation in climate change belief and pro-environmental behaviour remains an urgent challenge for the social sciences.

Economic Harmony—A Rational Theory of Fairness and Cooperation in Strategic Interactions

open access: yesGames, 2022
Experimental studies show that the Nash equilibrium and its refinements are poor predictors of behavior in non-cooperative strategic games. Cooperation models, such as ERC and inequality aversion, yield superior predictions compared to the standard game ...

Competition and partnership between conformity and payoff-based imitations in social dilemmas

open access: yesNew Journal of Physics, 2018
Learning from a partner who collects a higher payoff is a frequently used working hypothesis in evolutionary game theory. One of the alternative dynamical rules is when the focal player prefers to follow the strategy choice of the majority in the local ...

Institutions and the performance of coupled infrastructure systems

open access: yesInternational Journal of the Commons, 2016
Institutions, the rules of the game that shape repeated human interactions, clearly play a critical role in helping groups avoid the inefficient use of shared resources such as fisheries, freshwater, and the assimilative capacity of the environment ...

Cognitive Hierarchy Theory and Two-Person Games

open access: yesGames, 2017
The outcome of many social and economic interactions, such as stock-market transactions, is strongly determined by the predictions that agents make about the behavior of other individuals.

Counterfactual-Based Action Evaluation Algorithm in Multi-Agent Reinforcement Learning

open access: yesApplied Sciences, 2022
Multi-agent reinforcement learning (MARL) algorithms have made great achievements in various scenarios, but there are still many problems in solving sequential social dilemmas (SSDs).
