Altruism

Altruism

Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.

Egoism and Altruism

Egoism and Altruism

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Inclusive Fitness

Inclusive Fitness

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Equity Theory

Equity Theory

Equity theory explains how our sense of fairness influences the dynamics of close relationships. Rooted in social psychology, the theory posits that individuals evaluate fairness by comparing the ratio of their contributions to the rewards they receive. Relationship satisfaction is highest when these ratios are perceived as balanced between partners, promoting mutual reciprocity and a sense of justice.Equity vs. Equality in RelationshipsEquity is distinct from equality. Fairness does not...

Persuasion Strategies

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Social Exchange Theory

Social Exchange Theory

As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...

Summary

Understanding altruistic behavior requires expanding bargaining theories. Research suggests focusing on normative conditions, not just actual ones, is key to explaining generosity and cooperation in resource allocation.

Area of Science:

Behavioral Economics
Game Theory
Social Psychology

Background:

Traditional bargaining frameworks struggle to fully explain altruistic behavior.
Existing models often overlook the role of social norms and fairness perceptions.

Purpose of the Study:

To explore how bargaining theory can be expanded to incorporate altruism.
To investigate the significance of normative conditions in bargaining scenarios involving generosity.

Main Methods:

Conceptual analysis of bargaining frameworks.
Theoretical modeling of resource-rational bargaining under normative constraints.

Main Results:

Accommodating altruism necessitates a shift towards bargaining under normative conditions.

Normative bargaining provides a more robust explanation for seemingly non-self-interested actions.

Conclusions:

Bargaining theory needs to emphasize normative conditions to adequately explain altruism.
Further research is needed to develop resource-rational bargaining models under normative conditions.
