ABSTRACT Drawing from the Social Identity Model of Collective Action, this study investigates whether Islamophobic political agitation increases perceived discrimination and support for collective action among young Muslims. Using a longitudinal experimental design, we exposed young Muslims aged 18 to 37 years (n = 143) to a variety of anti–Islamic right-wing populist social media messages either once (i.e., single exposure) or at several different time points (i.e., repeated exposure). Our findings show, for the first time, that anti–Islamic political messages not only increased perceived discrimination immediately after exposure, but that this effect was still detectable 2 and 3 weeks after initial exposure. Repeated exposure did not lead to an incremental effect beyond that of one-time exposure. Our findings also showed that perceived discrimination predicted support for nonviolent collective action, but not for violent collective action to improve young Muslims’ social status both after single and repeated exposure. From a democratic perspective, these findings are encouraging and have important theoretical and methodological implications.

穆斯林采取行动。接触反伊斯兰民粹主义政治信息如何影响年轻穆斯林对集体行动的支持：一项纵向实验

摘要 根据集体行动的社会认同模型，本研究调查了伊斯兰恐惧症的政治骚动是否会增加年轻穆斯林对集体行动的感知歧视和支持。使用纵向实验设计，我们将 18 至 37 岁的年轻穆斯林（n = 143）一次（即单次暴露）或在几个不同的时间点（即， 反复接触）。我们的研究结果首次表明，反伊斯兰政治信息不仅在暴露后立即增加了感知歧视，而且在初次暴露后 2 和 3 周仍可检测到这种影响。重复暴露不会导致超过一次暴露的增量效应。我们的研究结果还表明，感知到的歧视预示着对非暴力集体行动的支持，但不支持通过暴力集体行动来改善单身和反复暴露后年轻穆斯林的社会地位。从民主的角度来看，这些发现令人鼓舞，并具有重要的理论和方法学意义。
