Group membership refers to the social connection individuals have with a specific group, which can be based on shared interests, goals, or characteristics. This membership can influence behavior, attitudes, and identity, as individuals often adopt the norms and values of the group they belong to. Belonging to a group can provide emotional support, a sense of belonging, and opportunities for collaboration. It can also lead to in-group favoritism, where members may prioritize the interests of their group over others. Understanding group dynamics is essential in various fields, including psychology, sociology, and organizational behavior.
