What effect does the institutional design of international organizations (IOs) have on their domestic support? In this article, we focus on interactions between citizens’ social identity and institutional characteristics that may have the potential to polarize citizens’ IO attitudes. We argue that citizens’ cosmopolitan identity makes them react in diametrically opposed ways to IO settings on the authority dimension. Transferring more authority to an IO may make citizens with higher levels of cosmopolitan identity more supportive of the IO, while citizens with lower levels of cosmopolitan identity should become even more skeptical. We test our expectations by conducting a factorial survey experiment in six different countries. The empirical results support our argument. As cosmopolitan identity is strongly connected to the newly evolving domestic cleavage regarding international cooperation and global governance, reforms to IO authority settings thus have the potential to further increase the polarization of domestic attitudes toward IOs.

国际组织 （IO） 的机构设计对其国内支持有什么影响？在本文中，我们关注公民的社会身份与制度特征之间的相互作用，这些相互作用可能会使公民的 IO 态度两极分化。我们认为，公民的世界性身份使他们对权威维度上的 IO 设置的反应截然相反。将更多权力转移给 IO 可能会使具有较高层次世界主义身份的公民更支持 IO，而具有较低世界主义身份层次的公民应该变得更加怀疑。我们通过在 6 个不同的国家/地区进行因子调查实验来检验我们的预期。实证结果支持我们的论点。由于世界性身份与国际合作和全球治理方面新发展的国内分裂密切相关，因此对 IO 权威设置的改革有可能进一步加剧国内对 IO 的态度两极分化。
