Balancing two needs
Brewer (1991) argued that people have two opposing needs: a need for assimilation, to gain security by belonging to a larger group, and a need for differentiation, to have a distinct identity separate from others. A group that is too large and inclusive fails to satisfy the need for differentiation, while one that is too small and unusual fails to satisfy the need to belong. She therefore predicted that people identify most strongly with optimally distinct groups where the two needs are in balance. This moved Snyder and Fromkin's (1980) work on the need for uniqueness to the group level.
Evidence and levels of identity
Brewer and Gardner (1996) distinguished the personal self, the relational self in close relationships and the collective self as a group member, locating optimal distinctiveness at the collective level. Pickett and colleagues (2002) showed experimentally that heightening the need to belong or to be distinct leads people to apply their group's traits more strongly to themselves, a process called self-stereotyping. This suggests that the depersonalization described by self-categorization theory can be driven by motives. The theory also explains why members of minority groups often hold strong group identities.
Applications and critiques
Hornsey and Jetten (2004) reviewed strategies people use to retain individuality within groups, such as joining subgroups or identifying with groups that value individualism. Brewer (2007) argued that these needs arose because humans evolved in small cooperative groups and extended the discussion to intergroup prejudice and conflict. The theory is applied to brand and consumer identity, organizational identification and fandom. Critics note that the optimal point is hard to measure in advance and that the weight of the two needs varies across cultures. Leonardelli and colleagues (2010) synthesized the research, including these debates.
FAQ
- What is optimal distinctiveness theory in simple terms?
- People want to belong somewhere but do not want to be exactly like everyone else, so they like moderately distinctive groups that satisfy both wishes at once.
- Why can minority group members have strong identities?
- Small groups provide both a sense of belonging and a sense of being distinct from others, so both needs are met and identification can be stronger.
