概括
惩罚孤独者可能会破坏公共产品游戏中的合作动态. 在特定条件下,这种惩罚可以导致纯粹合作的稳定状态或保护合作者的混合阶段.
科学领域:
- 进化游戏理论 进化游戏理论
- 行为经济学是一种行为经济学.
- 社会动力学 社会动力学
背景情况:
- 合作往往是由合作者,叛逃者和孤独者之间的循环动态维持的.
- 叛逃者利用合作者,但循环性质并不能保证合作者的长期成功.
- 孤独者对合作者施加制裁是经济互动中观察到的现象.
研究的目的:
- 调查孤独者惩罚合作者是否可以改变公共产品游戏中既定的循环动态.
- 探讨在哪些条件下合作可以稳定,甚至导致纯粹的合作者阶段.
- 分析一个包含惩罚孤独者的四种策略游戏的进化稳定性和空间动态.
主要方法:
- 开发一个进化模型,用于四种策略游戏 (合作者,叛逃者,传统的孤独者,惩罚孤独者).
- 在结构化人口中分析空间动态.
- 检查进化模式,战略分布和阶段过渡.
主要成果:

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

01:37Social Loafing
34.5K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

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.

40.8K
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.

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?
