Zmigrod et al. (2019a, Frontiers in Psychology, 10, 989) demonstrated that lower levels of cognitive flexibility predict a higher willingness to fight and die for the national in-group. We conducted a registered direct replication of their Study 1. Extending the original study, we examined whether the documented relationship held when a self-report measure for cognitive flexibility was introduced and when identity fusion was controlled for. We also investigated whether cognitive inflexibility predicts normative pro-group behaviour intentions.

认知僵化是否可以预测暴力极端主义行为意图？Zmigrod 等人的注册直接复制报告，2019

兹米格罗德等人。(2019a, Frontiers in Psychology, 10, 989) 表明，较低水平的认知灵活性预示着更高的为民族内群体而战和牺牲的意愿。我们对他们的研究 1 进行了注册的直接复制。扩展原始研究，我们检查了当引入认知灵活性的自我报告测量以及控制身份融合时，记录的关系是否成立。我们还调查了认知僵化是否能预测规范的亲群体行为意图。
