Which term refers to individuals or groups that are seen as existing outside of one's own group?

The term that refers to individuals or groups perceived as existing outside of one's own group is "out-group." This concept is essential in social psychology as it highlights the distinction between an individual's group identity (the in-group) and those who do not belong to that group (the out-group).

When discussing group dynamics, the in-group is typically associated with a sense of belonging, shared identity, and common interests, whereas the out-group may be viewed with suspicion or negativity. This can lead to biases and stereotypes against those in the out-group because they are perceived as different or as having contrasting values, beliefs, or behaviors. Understanding this terminology helps in analyzing social interactions and the impact of group affiliations on behavior and perceptions.

The other terms listed do not accurately describe this concept. "In-group" denotes the group to which an individual identifies as part of, "subgroup" refers to a smaller division within a larger group, and "core group" usually indicates a central or essential part of a larger organization or community. None of these terms captures the specific idea of individuals or groups existing outside one's own group as well as "out-group" does.
