    Cognitive Load and Fairness

    In games like the ultimatum game, where a proposer offers a split of money and the responder can accept or reject, the responder is less likely to reject an offer when they are under cognitive load. This suggests they are more likely to settle for an unfair share when they have less time and energy to consider the situation.

    Fear and Cooperation

    Fear of punishment for acting selfishly or fear of being a sucker (cooperating when others don't) can reduce cooperation in games like the prisoner's dilemma. This fear can lead to more generous offers from proposers, even when anonymity is guaranteed.

    Anonymity and Greed

    In the dictator game, where the responder has no power to reject the offer, proposers still tend to offer more than they would if they were purely self-interested. However, this generosity decreases significantly when participants are convinced that their actions are anonymous. This suggests that even in anonymity, people are motivated by factors other than pure self-interest.

    Fairness in the Dictator Game

    In the ultimatum game, even though the responder cannot reject the offer and the proposer can take everything, a majority of proposers still offer a fair split. This suggests that people are not always driven by self-interest but are also influenced by fairness concerns.

    Social Value Orientations

    People have different social values orientations. Prosocial individuals prioritize maximizing joint gain and equality, while individualists prioritize maximizing their own gains. This influences how they interact in games and situations involving shared resources or decision-making.

    Study Notes

    Cooperation and Coordination

    • Game theory analyzes interactions between rational agents with multiple strategies, considering payoffs contingent on other players' actions.
    • Game theory assumes common knowledge of rules and players' rationality to predict convergence toward rational solutions.
    • Ultimatum games involve a proposer offering a portion of a sum to a responder, who can accept or reject. Typically, offers below 20% are frequently rejected.
    • Behavioral game theory studies how individuals actually behave in interactive situations, contrasting with theoretical perfect rationality.
    • Prisoner's dilemma, a key game theoretical concept (definition skipped), often predicts defection as the Nash equilibrium where both players defect. However, individuals frequently cooperate more than predicted, particularly in repeated games.
    • Public goods games involve individuals contributing resources to a shared pool, leading to collective benefits with free-riding potential.
    • Tit-for-tat strategy (repeated games) is a successful cooperative strategy based on reciprocal cooperation.
    • Cooperation isn't always motivated by moral imperative, but rather is often influenced by awareness of other players' actions or perceived strategies.
    • Cooperation can decrease if a person's perspective is purely cognitive (focuses on how to benefit self, even if it is costly to others).

    Fear, Greed, and Punishment

    • Fear of punishment/being a sucker influences cooperation in games.
    • Dictator games further demonstrate selfish behavior when fear is eliminated as compared with the Ultimatum game.
    • Revenge motives can drive cooperation in the absence of direct gain.
    • Experiencing another's suffering while defecting or cooperating affects the observer's behavior.
    • Differences in values amongst people's impact their cooperation level.

    Differences in Values

    • Social value orientations categorize individuals based on how much they value joint outcomes vs. relative gains (e.g., prosocial, individualistic, competitive).
    • Upward counterfactual thinking (what could have been better) is correlated with increased future cooperation in public good games; while downward counterfactual thinking associated with less cooperation.
    • Prosocial people have a different emotional response to fair vs. unfair partners.

    Cooperation and Economic Success

    • Societies where cooperation with non-immediate kin or trading is more common display higher cooperation.
    • Cooperative behavior depends on how people perceive the exchange.

    Trust, Generosity and Communication

    • Trust games examine how individuals react when trusting another player with a potential reward.
    • Trust and trustworthiness vary based on reputation and individual differences; as well as culture.
    • Communication promotes cooperation, especially among non-trusting participants.

    Economic Games and Fairness

    • Individuals exhibit fairness motivations in economic games even when they don't materially benefit.
    • Cultural variability significantly impacts fairness and cooperation in economic games, possibly due to factors such as market integration and religion.

    Social Neuroeconomics

    • Neural circuitry mediates social preferences by engaging brain areas linked to reward, emotional response and theory of mind.
    • The ventral striatum and other areas show heightened activation when cooperation, fairness, or trust is involved.
    • Oxytocin influences trust and cooperation by decreasing fear and promoting bonding.
