Sticking together or falling apart: In-group identification as a psychological determinant of group commitment versus individual mobility

Two experiments investigated how in-group identification, manipulated with a bogus pipeline technique affects group members' desire for individual mobility to another group. In the first experiment (N = 88), the in-group had low status, and group boundaries were either permeable or impermeable. Low identifiers perceived the group as less homogeneous, were less committed to their group, and more strongly desired individual mobility to a higher status group than did high identifiers. The structural possibility of mobility afforded by permeable group boundaries had no comparable effect. The second experiment (N = 51) investigated whether in-group identification can produce similar effects when relative group status is unknown. Even in the absence of an identity threat, low identifiers were less likely to see the groups as homogeneous, felt less committed to their group, and more strongly desired individual mobility than did high identifiers. Results are discussed with reference to social identity and self-categorization theories.
