Outgroup derogation refers to the tendency to view and treat members of a group that one does not belong to, or an 'outgroup', in a negative or dismissive manner. This phenomenon often stems from an inherent bias that favors one's own group, leading to negative stereotypes, prejudices, and discrimination against those perceived as outsiders. This behavior can escalate intergroup tensions and conflicts, significantly impacting social dynamics and contributing to broader societal issues such as prejudice.
