An in-group is a group of people who feel a sense of solidarity and exclusivity in relation to nonmembers. They often share common values, beliefs, or interests and may discriminate against out-group members. Dominance hierarchies refer to the social ranking within a group or society, while out-groups are the opposite of in-groups and are viewed as outsiders or those not belonging to the group. Support groups are groups of individuals who come together to share common experiences and provide emotional support to one another.
