"Us vs. Them" concept

The "Us vs. Them" concept describes a psychological or social tendency where people categorize others into groups, identifying strongly with their own group ("Us") while viewing outsiders ("Them") as different or even threatening. This dynamic can foster solidarity within the group but also lead to bias, prejudice, and conflict between groups. It stems from a need for belonging and identity and can influence attitudes, decision-making, and social interactions, often making it harder to see shared humanity or to cooperate across group boundaries.
