Summary
Conformity promotes cooperation in social dilemmas when positive relationships dominate. However, network adaptation and conformity can lead to stable coexistence of cooperation and defection.
Area of Science:
- Evolutionary Game Theory
- Social Network Analysis
- Behavioral Economics
Background:
- Human behavior is influenced by conformity, yet its role in social dilemmas, especially when payoff maximization is assumed, is under-researched.
- Previous models often overlook the impact of network structure and relationship dynamics on cooperation.
Purpose of the Study:
- To investigate the role of conformity in a generalized prisoner's dilemma within a signed network.
- To explore how network structure, conformity, and relationship adaptation influence the evolution of cooperative behaviors.
Main Methods:
- Developed a generalized prisoner's dilemma model incorporating conformity within a signed network framework.
- Utilized agent-based simulations to analyze the dynamics of cooperation and defection under varying network conditions.
Main Results:
- Conformity promotes cooperation when positive ties are prevalent; negative ties can hinder this effect.
- Homophily and xenophobia dynamics lead to stable coexistence and evolutionary equality of cooperators and defectors.
- Higher rates of relationship sign adjustment favor cooperation, with conformity mediating this adaptation's impact.
Conclusions:
- Conformity is a significant factor in promoting cooperation in social dilemmas, contingent on network structure.
- Network adaptation and conformity collectively shape population-wide dynamics, potentially creating stable attractors or repellers for different strategies.

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,...

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

01:58Cooperative Allosteric Transitions
7.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

02:13Cooperative Binding of Transcription Regulators
6.5K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome. Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

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).
