Norms in a group can be established through previous experiences and behaviors, which reflects how individuals interact based on their past interactions and learned expectations. When group members share collective experiences, they begin to develop informal guidelines or norms that dictate appropriate behavior, communication styles, and decision-making processes. These norms emerge organically as members observe and model each other's behaviors and reactions within the group context.
This process tends to be fluid and adaptive, allowing the group to establish a set of shared expectations that are often unspoken but understood by the members. This can lead to a cohesive group dynamic as members align with these established norms, actively participating in shaping and reinforcing them over time. In contrast, establishing norms solely through explicit discussions, commands from a leader, or written agreements can create limitations by making the norms overly rigid or disconnected from the group's actual working dynamics and relationships.
