Which bias can lead to homogeneous group dynamics?

In-group bias is the tendency to favor members of one's own group over those in other groups. This bias often leads to homogeneous group dynamics because individuals typically form stronger bonds and exhibit preferential treatment towards those who share similar characteristics, beliefs, or identities. As a result, the group may become more similar over time, as members choose to associate primarily with each other while excluding outsiders.

This phenomenon manifests in various social contexts, such as workplace teams, social clubs, and community groups, where people seek comfort and validation within their in-groups. The preference for familiarity and shared experiences can stifle diversity of thought, limiting the perspectives and experiences that inform the group's dynamics.

Understanding in-group bias is essential in sociology as it sheds light on how social cohesion can simultaneously foster a sense of belonging while also reinforcing divisions and inequalities between different groups.
