This contribution seeks to illuminate the looming phenomenon of demultilateralisation and the return of and to the nation state, i.e. closure. Whereas many reasons for opening and closure have been discussed by Habermas in his eminent essay, we aim at providing an additional dimension, taking a psychological point of view and analysing this proclivity from a behaviourally informed perspective. Following a short recapitulation of the evolution towards postnationalism, we briefly sketch the current phenomenon of demultilateralisation and renationalisation. We then contribute to the current debate by providing cognitive psychological insights drawing on well‐researched biases that offer the greatest potential to explain the current outbreak of closing tendencies, namely prospect theory, including the endowment effect, framing, the availability bias and so‐called hawkish biases. This may add an explanatory dimension to why nationalistic politics have become again the beguiling sanctuary of the people. We attempt to define scope conditions of closure

去多边化：认知心理学视角

这一贡献旨在阐明即将到来的去多边化现象以及民族国家的回归，即关闭。尽管哈贝马斯在他的著名论文中讨论了许多打开和关闭的原因，但我们的目标是提供一个额外的维度，从心理学的角度并从行为知情的角度分析这种倾向。在简要回顾后民族主义的演变之后，我们简要概述了当前的去多边化和再国家化现象。然后，我们通过利用经过充分研究的偏见提供认知心理学见解来为当前的辩论做出贡献，这些偏见最有可能解释当前关闭趋势的爆发，即前景理论，包括禀赋效应、框架、可用性偏见和所谓的鹰派偏见。这可能为民族主义政治为何再次成为人民的诱人庇护所增加了一个解释维度。我们尝试定义关闭的范围条件
