Summary
Celebrity influence and irrational imitation, driven by social status, can maintain long-term cooperation in social systems. Network structures like scale-free and community enhance cooperation
Area of Science:
- Social Sciences
- Game Theory
- Network Science
Background:
- Evolutionary game theory is a key framework for studying cooperation.
- Social status significantly influences individual decision-making in social interactions.
Purpose of the Study:
- To investigate how social status and imitation mechanisms affect group cooperation.
- To reveal the group cooperation decision-making mechanism led by celebrities.
Main Methods:
- Developed a classification imitation model incorporating the celebrity effect and incomplete egoism.
- Utilized large-scale Monte Carlo simulations to analyze the model's dynamics.
Main Results:
- Incomplete egoism, while not stimulating cooperation, ensures its stable existence.
- Scale-free and community network structures facilitate the widespread diffusion and long-term survival of cooperation.
Conclusions:
- Celebrity-driven imitation and network topology are crucial for sustained cooperation.
- Findings offer insights into understanding and controlling cooperation in complex social systems.

The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

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...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
