Concept and cues
Campbell (1958) borrowed from Gestalt principles of perception the cues that make a collection of people look like a single social entity. Key among them are common fate, moving together and experiencing the same outcomes; similarity among members; and proximity. Later research showed that interaction among members, common goals and internal organization and structure also raise entitativity. Lickel and colleagues (2000) showed that intimacy groups such as families and friends and task groups such as work teams are highest in entitativity, followed by social categories such as gender or nationality and loose associations such as people on the same bus.
Group perception and stereotyping
Hamilton and Sherman (1996) argued that the more entitative a group, the more people process it as if it were an individual. They expect consistent dispositions, integrate information in memory and locate the causes of behavior in the group's essence. Crawford and colleagues (2002) showed that in highly entitative groups one member's traits readily transfer to others, so members are seen as interchangeable and stereotypes form. Abelson and colleagues (1998) argued that entitative outgroups seem able to act in unison and therefore feel more threatening. This works together with the outgroup homogeneity effect.
The ingroup and identification
Entitativity also affects attitudes toward the ingroup. Castano and colleagues (2002) showed that the more people perceive their own group as entitative, the more strongly they identify with it and the greater their ingroup bias. Hogg and colleagues (2007) found that people who feel uncertain are more drawn to, and identify more with, groups that have clear boundaries and high entitativity. This is a core basis of uncertainty-identity theory and explains why extreme, tightly knit groups appear attractive in anxious times.
FAQ
- What is entitativity in simple terms?
- The degree to which a collection of people looks like "one real group" rather than "just some people."
- What happens when entitativity is high?
- Members are seen as similar and interchangeable, so stereotypes form easily; outgroups seem more threatening, and ingroups attract stronger identification.
