Abstract
People can have a sense of collective ownership of a particular territory, such as "our" country, "our" neighborhood, and "our" park. Collective psychological ownership is argued to go together with rights and responsibilities that have different behavioral implications. We found that collective psychological ownership leads to perceived determination right, and indirectly to the exclusion of outsiders from "our" place. Simultaneously, collective psychological ownership leads to perceived group responsibility, and indirectly to engagement in stewardship behavior. These results were found among Dutch adults, cross-sectionally in relation to their country (Study 1; N = 617) and a neighborhood (Study 2; N = 784), and experimentally in relation to an imaginary local park (Study 3; N = 384, Study 4; N = 502, both pre-registered). Our research shows that the feeling that a place is "ours" can, via perceived rights and responsibilities, result in both exclusionary and prosocial behavioral tendencies.
