Previous research has consistently found that more political conservatism is related to higher anti-vaccination attitudes. However, little work has investigated how intellectual humility could potentially contribute to this relationship. Employing the social judgment theory of attitude change, we examined whether conservatism could mediate the association between intellectual humility and anti-vaccination attitudes. Participants (N = 1,293; 40.1% female; M_age = 38.23 years, SD_age = 11.61, range of age was 18–78) completed a multifaceted measure of intellectual humility, an assessment of four types of anti-vaccination attitudes, and a measure of political orientation. Results from structural equation modeling revealed that decreased levels of most aspects of intellectual humility (i.e., independence of intellect and ego, openness to revising one’s viewpoint, and lack of intellectual overconfidence) are associated with more conservative political views, which in turn is associated with stronger anti-vaccination attitudes, particularly worries about unforeseen future effects, concerns about commercial profiteering, and preference for natural immunity. These findings suggest that intellectual humility could reflect one’s latitude widths, thereby predicting their openness to vaccine massaging, and thus may play an important role in addressing anti-vaccination attitudes, especially when politics is involved.

先前的研究一致发现，政治保守主义程度越高，反疫苗接种态度越高。然而，很少有研究调查智力谦逊如何可能对这种关系做出贡献。利用态度改变的社会判断理论，我们研究了保守主义是否可以调节知识谦逊与反疫苗态度之间的关联。参与者（N  = 1,293；40.1% 女性；M_年龄 = 38.23 岁，SD_年龄 = 11.61，年龄范围为 18-78 岁）完成了智力谦逊的多方面测量、对四种反疫苗态度的评估，以及政治倾向的衡量标准。结构方程模型的结果显示，智力谦逊的大多数方面的水平下降（即智力和自我的独立性、修正自己观点的开放性以及缺乏智力上的过度自信）与更保守的政治观点有关，而这又与更保守的政治观点有关。更强烈的反疫苗接种态度，尤其是对不可预见的未来影响的担忧、对商业暴利的担忧以及对自然免疫的偏好。这些发现表明，智力上的谦逊可以反映一个人的纬度，从而预测他们对疫苗按摩的开放程度，从而可能在解决反疫苗态度方面发挥重要作用，特别是在涉及政治时。
