Social identity has a big impact on how well groups work together and how conflicts arise. This idea comes from something called Social Identity Theory (SIT). SIT tells us that people get a sense of who they are from being part of a group. While this can help groups stick together, it can also make tensions with other groups worse.

Group Cohesion:

1. Shared Identity: When people feel connected to a group, it helps everyone feel like they belong. This sense of belonging leads to higher levels of trust, teamwork, and happiness within the group.
2. In-Group Favoritism: Groups tend to prefer their own members. This means they are more likely to work well together. Studies show that people are 20-30% more willing to help someone from their own group compared to someone from another group.

Intergroup Conflict:

1. Us vs. Them Mentality: Having a strong social identity can lead to unfair treatment of people outside their group. Research shows that groups with a strong identity are 36% more likely to judge others unfairly.
2. Conflict Escalation: When people feel their group is being threatened, conflicts can grow. For example, studies showed that if someone thinks their group is not valued, they might become 40% more aggressive towards other groups.

Statistics:

• A survey from 2019 found that 67% of people had negative feelings toward groups that were different from their own.
• An experiment showed that people who talked about their identities were 50% more likely to develop negative views about other groups.

In short, social identity can both help groups work better together and create issues with other groups. It’s important to manage how groups interact to help everyone get along, especially in diverse settings.
