The Black Lives Matter (BLM) protests and the COVID-19 pandemic are two distinct forces that have introduced cultural change around the world by respectively challenging or amplifying the status quo. Past research demonstrates that cultural change can be perceived as threatening. Thus, the change brought upon by the BLM movement and the pandemic may be reducing support toward the BLM movement and reducing support for creating a new normal following the pandemic (i.e., creating new social norms). Based on the Cultural Inertia Model, we predicted that highlighting the BLM protests and the COVID-19 pandemic as agents of change would hinder support toward each agent of change. In essence, two agents of change might be too much change. We also hypothesized that national nostalgia and prostalgia would serve as psychological anchors or propellers that hinder or facilitate support toward each agent of change. Our findings demonstrated that highlighting the BLM protests and the pandemic as agents of change did not cause differences in support toward the BLM movement or creating a new normal. However, national nostalgia and prostalgia served as individual difference measures that respectively reduced and facilitated support toward the BLM movement and the creation of new social norms.

全国的怀旧情绪和怀旧情绪预示着对 Black Lives Matter 运动的支持，并在大流行之后创造新常态

Black Lives Matter (BLM) 抗议和 COVID-19 大流行是两种截然不同的力量，它们分别挑战或扩大了现状，在世界范围内引入了文化变革。过去的研究表明，文化变革可以被视为具有威胁性。因此，BLM 运动和大流行带来的变化可能正在减少对 BLM 运动的支持，并减少对在大流行之后创建新常态（即创建新的社会规范）的支持。基于文化惯性模型，我们预测将 BLM 抗议和 COVID-19 大流行作为变革推动者会阻碍对每个变革推动者的支持。从本质上讲，两个变革的推动者可能是太多的变革。我们还假设，民族怀旧和怀旧将作为心理锚或推进器，阻碍或促进对每个变革推动者的支持。我们的研究结果表明，强调 BLM 抗议和大流行作为变革的推动者不会导致对 BLM 运动的支持或创造新常态的差异。然而，民族怀旧和怀旧作为个体差异措施，分别减少和促进了对 BLM 运动的支持和新社会规范的创建。
