In social psychology, entitativity is the degree to which a group is perceived as a cohesive, unified entity. It describes how much a collection of individuals is seen as "group-like" and bonded by common attributes, such as shared goals or traits. Perceived entitativity occurs when people view an aggregate of individuals as a single entity, attributing to them common characteristics or a collective purpose. Thus, a group is seen as a "real" group when its members' behaviors are seen as stemming from shared goals or traits.
Research shows that people consistently distinguish between different types of groups based on perceived entitativity. Intimacy groups, such as family and friends, are generally considered the most entitative. Task groups, like committees, come next, followed by social categories (e.g., gender, race). Finally, loose associations—such as people who like classical music or those waiting in line at a bank—are seen as the least entitative.
Entitativity plays a key role in shaping how individuals perceive and evaluate social groups and their members. People tend to make more polarized judgments and have stronger emotional responses towards highly entitative groups, which impacts in-group and out-group dynamics. Individuals are more likely to rely on stereotypes when assessing group members, as well as recall more information about highly entitative groups. For in-groups, greater entitativity can enhance group members' sense of group identification and positivity towards the group.
