Also known as: Out group Homogeneity Bias
El sesgo de homogeneidad del exogrupo es la tendencia a percibir a los miembros de un grupo externo como más similares entre sí que los miembros del propio grupo. En conjuntos de datos y evaluaciones, puede producir etiquetas simplificadas, estereotipadas o menos matizadas para personas ajenas al grupo del anotador.
The tendency to see out-group members as more alike than in-group members when comparing attitudes, values, personality traits, and other characteristics. In-group refers to people you interact with regularly; out-group refers to people you don't interact with regularly. If you create a dataset by asking people to provide attributes about out-groups, those attributes may be less nuanced and more stereotyped than attributes that participants list for people in their in-group. For example, Lilliputians might describe the houses of other Lilliputians in great detail, citing small differences in architectural styles, windows, doors, and sizes. However, the same Lilliputians might simply declare that Brobdingnagians all live in identical houses. Out-group homogeneity bias is a form of group attribution bias. See also in-group bias.
