A developmental investigation of group concepts in the context of social hierarchy: Can the powerful impose group...

Group membership is not always voluntary and can be imposed within a social context; moreover, those with power disproportionately shape group membership. We asked if children and adults view group membership as imposed by the powerful. We undertook four studies (465 children ages 4-9, 150 adults): Studies 1-2 used novel minimal groups; Study 3 used 'cool' and 'uncool'; Study 4 used novel ethnic groups. In the first three studies, children saw groups varying in power asserting that a non-categorized individual ought to belong to one of the operating groups in the context. Adults indicated that the declarations of the high-power group (and only the high-power group) made the individual a member of the declared group. Young children rejected that group membership could be imposed. In Study 4, children of all ages reasoned that the high-power group could decide membership for a consenting individual and impose clothing restrictions on a non-consenting individual; unlike adults, children of all ages did not reason the high-power group could impose group membership more frequently than chance. Taken together, adult participants consistently reasoned that group membership was imposed and disproportionately by those with power but children, more often than adults, reasoned that group membership was voluntary.
