What factor significantly influences the classification of team members into In-Group or Out-Group?

The classification of team members into In-Group or Out-Group is significantly influenced by the manager's preferences and perceptions. This concept is rooted in social categorization theory, where leaders often evaluate team members based on subjective criteria, making distinctions between those they favor (In-Group) and those they view less favorably (Out-Group).

Managers may develop perceptions based on individual performance, communication styles, or alignment with their own values and beliefs, which can lead to a biased classification of team members. This can further impact team cohesion, collaboration, and overall performance, as members of the In-Group may receive more support and resources compared to their Out-Group counterparts. The manager's role in shaping team dynamics is crucial, making their preferences and perceptions a key factor in determining who belongs to which group within the team structure.
