What is entitativity?
Entitativity is how far a set of people is perceived as one coherent unit. The research maps four kinds of group and traces what changes in the perceiver once a group feels real.
Answer to the question
What is entitativity?
Entitativity is how far a set of people is perceived as a single, coherent unit rather than a collection of individuals. Donald Campbell introduced the term in 1958, and Brian Lickel and colleagues showed in 2000 that people sort groups into four types that differ in how entitative they seem.
Key takeaways
- Campbell introduced the term entitativity in 1958, in a paper on common fate, similarity and other indicators that a set of people is a social entity.
- Lickel and colleagues (2000) had participants rate forty groups in two countries; the ratings clustered into intimacy groups, task groups, social categories and loose associations.
- Rutchick, Hamilton and Sack (2008) found in two experiments that judgements of entitativity rested on similarity or on interaction according to how the group was construed.
- Crawford, Sherman and Hamilton (2002) found in three experiments that traits travelled from one member to the others more when the group was seen as high in entitativity.
- Waytz and Young (2012) reported a trade-off: the more mind a group was credited with, the less mind was credited to its individual members.
A family seems like a single unit, and the people waiting at a station do not, even when they stand closer together. Nothing about the station crowd is hidden from view. What it lacks is the look of one thing, and since 1958 social psychologists have had a name for that look. Entitativity is how far a set of people is perceived as one coherent unit rather than as a number of separate individuals. Colin Fisher, a professor of organisations at University College London, uses the word groupiness in The Collective Edge for a continuum that runs from a mere social category, through a crowd and a set of people acting side by side, to a real team.
Fisher's continuum looks at groups from the side of performance, and the entitativity research looks at them from the side of perception. Most of what is known on the perception side comes from asking people to rate groups.
Four Kinds of Group in Two Countries
The term dates from 1958, when Donald Campbell used it in a paper in Behavioral Science on common fate, similarity and other indicators of whether an aggregate of persons has the status of a social entity. The title already carries the programme. A perceiver does not see a group directly. The perceiver infers it from cues, and Campbell's title names two of them, common fate and similarity. Later work asked which cues people actually use, and how many kinds of group there are to be told apart.
Counting the kinds of group took a large rating exercise. Participants rated forty groups on eight properties, including size, duration and how alike the members were, and then rated how much each group had the quality of a unit. Brian Lickel and five colleagues ran the first study with participants in the United States and the second with participants in Poland, and published both in 2000. Statistical clustering of the ratings produced the same four types of group in both countries:
- Intimacy groups, of which a family is one illustration.
- Task groups, such as a work committee.
- Social categories, which are large and whose members resemble one another.
- Loose associations, which are easy to join and easy to leave.
The map breaks the single word group into kinds that differ in how real they seem.
A review chapter on group processes by Donelson Forsyth and Jeni Burnette, which cites this work, sums up where the impression comes from. People more readily see a set of people as a group when the members have strong bonds, interact often and share clear boundaries. Crowds, waiting lines and categories are less often seen that way.
The Frame an Observer Brings to Them
Campbell's cues raise a follow-up question: which one does the perceiver lean on? The answer, proposed by Abraham Rutchick and two colleagues in 2008, is that it depends on how the group is construed. A group can be thought of as a category of similar people or as a dynamic set of people acting on one another.
In two experiments, an analogy about bees was used to push participants towards one construal or the other. In the first, the cues that participants recalled and reported differed between similarity and interaction according to the construal. In the second, judgements of entitativity themselves rested on similarity or on interaction according to the construal. So the same collection of people can seem more or less unified depending on whether the observer looks at what the members share or at what they do together, a condition the 2000 map did not include.
Member, Unit and the Mind of a Group
Seeing a group as a unit changes how a single member is read. In three experiments in 2002, Matthew T. Crawford and two colleagues had participants learn about the behaviour of one member of a group. When the group was seen as low in entitativity, or as a mere collection of individuals, the traits inferred about that one person were stronger. When it was seen as high in entitativity, traits travelled from the one member to the others. On their account, high entitativity leads people to form an impression of the group and to apply it to every member.
Minds follow a similar pattern. The more a group was credited with a mind of its own, able to think, intend and plan, the less mental life people attributed to its individual members, a trade-off reported by Adam Waytz and Liane Young in 2012. Groups credited with a stronger collective mind were also seen as more cohesive. The two descriptions of the same people, as one actor or as a set of individuals, pull against each other. Cliques Are a Stress Response follows the same dimension inside friendship circles, using Michael Hogg's work on uncertainty and group identification.
Seen from the inside, the dimension carries weight of its own. The third study in Lickel's paper had people rate groups they belonged to. Those ratings replicated the earlier ones. People valued their membership most in the groups that most resembled a single thing to them, so the impression of a unit counted for the members inside a group as well as for the observers outside it.
Common questions

What are the four types of group in entitativity research?
Lickel and colleagues (2000) found that participants' ratings clustered into intimacy groups, task groups, social categories and loose associations. The same four types appeared in a study in the United States and in one in Poland.
What does entitativity change about how people judge group members?
In three experiments by Crawford and colleagues (2002), traits inferred about one member were carried over to the other members more strongly when the group was seen as high in entitativity. Inferences about a single member were stronger when the group was seen as low in entitativity.
