Summary
Group size impacts online trust dilemmas, with women increasing cooperation in larger groups. Overall cooperation remains stable, but gender differences emerge in large-group dynamics.
Area of Science:
- Behavioral Economics
- Social Psychology
- Game Theory
Background:
- Online trust dilemmas are crucial for understanding social interactions.
- Group size is a key variable influencing collective behavior and decision-making.
- Previous research has yielded mixed results on the effect of group size on cooperation.
Purpose of the Study:
- To investigate the influence of group size on cooperative behavior in online trust dilemmas.
- To identify potential gender-specific responses to varying group sizes.
- To examine the robustness of findings when controlling for individual differences.
Main Methods:
- Conducted an online experiment involving trust dilemmas with group sizes ranging from 4 to 100 players.
- Measured levels of cooperation across different group sizes.
- Analyzed data for gender differences and controlled for factors like risk aversion and age.
Main Results:
- Overall cooperation levels remained stable irrespective of group size.
- Significant gender differences in cooperation were observed.
- Women demonstrated increased cooperation with larger group sizes and cooperated more than men in large groups.
Conclusions:
- Group size does not uniformly affect cooperation but reveals significant gender-based variations.
- Women's cooperative behavior is sensitive to group size, unlike men's.
- Future research should consider gender and large-group dynamics in online trust scenarios.

Social Loafing

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,...

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,...

Deindividuation
31.1K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Bystander Effect

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.
