‘This country is OURS’: The exclusionary potential of collective psychological ownership

Political campaign slogans, such as ‘Take back control of our country’ (United Kingdom Independence Party) and ‘The Netherlands ours again’ (Dutch Party for Freedom), indicate that right‐wing populism appeals to the belief that the country is ‘ours’, and therefore, ‘we’ have the exclusive right to determine what happens. We examined this sense of ownership of the country (i.e. collective psychological ownership [CPO]) with the related determination right in relation to exclusionary attitudes and voting behaviour. Among Dutch (Study 1, N = 572) and British (Study 2, N = 495) participants, we found that CPO explained anti‐immigrant and anti‐EU attitudes, and these attitudes in turn accounted for voting ‘leave’ in the 2016 Brexit referendum in the British sample (Study 2). Additionally, CPO was more strongly related to negative immigrant attitudes among right‐wing Dutch participants, whereas it was more strongly related to negative EU attitudes and voting ‘leave’ among left‐wing British participants. CPO contributes to the understanding of critical contemporary social attitudes and political behaviour.
