Final answer:
In-groups are groups of two or more people who interact frequently and share a common identity. These can be found in various settings and are characterized by regular interactions and a shared sense of communal identity. They are different from cliques, social networks, or mere crowds.
Step-by-step explanation:
Groups of two or more people who interact frequently and share a common identity are referred to as In-groups. These groups are characterized by regular interactions and a shared sense of purpose or alignment with the group's identity. Such groups can be found in various settings, including family units, workplaces, friend circles, and social clubs. A distinct feature of in-groups is that they can create a sense of belonging and may also generate exclusive behaviors, distinguishing members from non-members. Compared to cliques or social networks, in-groups often have a deeper emotional connection and shared responsibilities.
It is important to note the difference between an in-group and other types of social gatherings. For example, people standing in a queue at a coffee shop would be considered a crowd and not a group, because they do not necessarily interact or share a common identity. Similarly, a rally or belonging to a political party might not fit the definition of an in-group if it does not involve regular interaction and a shared identity.
