Group-identity completion and the symbolic value of property.

Building on symbolic self-completion theory, we conceptualize group identity as a goal toward which group members strive, using material symbols of that identity. We report four studies showing that the value placed on such material symbols (e.g., a building) depends on commitment to group identity, the extent to which a symbol can be used to represent in-group identity, and situational variability in goal strength induced through group-identity affirmation or threat. Our results suggest that property derives value from its capacity to serve as an effective means in the pursuit of group-identity goals. Implications for intergroup conflict are discussed.
