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.

“这个国家是我们的”：集体心理所有权的排他性潜力。

政治竞选口号，例如“夺回对我们国家的控制权”（英国独立党）和“荷兰再次成为我们的”（荷兰自由党），表明右翼民粹主义呼吁相信国家是“我们的” '，因此，'我们'拥有决定会发生什么的专有权利。我们研究了这种国家的主人翁意识（即集体心理所有权[CPO]）以及与排斥态度和投票行为相关的决定权。在荷兰人（研究 1，N  = 572）和英国人（研究 2，N = 495) 参与者，我们发现 CPO 解释了反移民和反欧盟的态度，这些态度反过来解释了英国样本中 2016 年英国脱欧公投中的投票“离开”（研究 2）。此外，CPO 与荷兰右翼参与者的消极移民态度密切相关，而与英国左翼参与者的欧盟消极态度和投票“离开”密切相关。CPO 有助于理解批判性的当代社会态度和政治行为。
