Losing what is OURS: The intergroup consequences of collective ownership threat

Collective ownership threat is the fear of losing control over what is perceived to be owned. In two experimental studies, we examined the intergroup consequences of collective ownership threat in relation to perceived owned territories. First, among a sample of Dutch adolescents (N = 227), we found that infringement of a hangout place owned by a group of friends led to more perceived collective ownership threat (and not symbolic threat), which was in turn related to more marking and anticipatory defending behavior. Second, among a sample of native Dutch adults (N = 338), we found that framing Turkish EU accession as an infringement of the collective ownership of the country led to more perceived collective ownership threat (and not symbolic and economic threat), which was in turn related to more opposition to Turkey’s possible accession. Our findings indicate that collective ownership threat is an important construct to consider in intergroup research.
