Residential mobility and conditionality of group identification

In three studies, we found that residential mobility accounts for cross-national, regional, and individual differences in the conditionality of identification with a group. In Study 1, participants from a mobile nation (US) showed more conditional identification with other group members than did participants from a stable nation (Japan). In Study 2, we found within-nation, regional variation in this tendency. Specifically, in residentially stable Japanese cities, the attendance to home baseball games was higher when the team was performing well than when it was performing poorly. In contrast, the attendance to the home games was not associated with the team’s performance. Finally, in Study 3 we found individual differences in the conditionality of group identification, such that frequent movers identified with the school more than non-movers did when the school was described favorably, whereas they distanced themselves from the school more than non-movers when their school was described unfavorably. These findings illustrate the role of residential mobility in individual, regional, and cross-national differences in the conditionality of group identification.
