What do we call those perceived as different or apart from our ingroup?

The term that refers to individuals or groups perceived as different or apart from one's own group (the ingroup) is "outgroup." Ingroup refers to the social group with which an individual identifies, often characterized by a sense of belonging and shared characteristics, values, or interests. In contrast, outgroup members are typically viewed as outsiders or others who do not share those same traits. This distinction plays a significant role in social psychology as it can lead to various interpersonal dynamics, including bias, discrimination, and stereotyping. Understanding the concept of outgroup helps illuminate social behaviors and attitudes in contexts such as intergroup conflict and cohesion. The dynamics between ingroup and outgroup can greatly influence social perception and interaction.
