We examined whether people who are prone to believe COVID-19 conspiracy theories are characterised by an especially strong concern for others or an especially strong concern for the self, and whether these orientations are associated with willingness to take a COVID-19 vaccine. We surveyed 4,245 participants from eight nations; three months later we re-contacted 1,262 participants from three nations. Belief in COVID-19 conspiracy theories was related to greater concerns about one's own safety, and lower concerns about the safety of close others. Furthermore, conspiracist ideation at Wave 1 predicted reluctance to take a COVID-19 vaccine at Wave 2, mediated through relative concern for self versus others. In sum, people who are high in conspiracy beliefs have relatively higher concern for the self relative to others, with troubling implications for public health.

阴谋论者在多大程度上关心自己与他人？COVID-19 测试用例

我们研究了容易相信 COVID-19 阴谋论的人是否具有对他人特别强烈的担忧或对自我特别强烈的担忧，以及这些倾向是否与接种 COVID-19 疫苗的意愿相关。我们对来自 8 个国家的 4,245 名参与者进行了调查；三个月后，我们重新联系了来自三个国家的 1,262 名参与者。对 COVID-19 阴谋论的信仰与对自身安全的更大担忧有关，而对亲密他人安全的担忧则较低。此外，第一波的阴谋主义观念预示着第二波人们不愿接种 COVID-19 疫苗，这是通过对自我与他人的相对关注来介导的。总而言之，阴谋论信念较高的人相对他人而言对自我的关注程度相对较高，这对公共健康产生了令人不安的影响。
