The association of medical experts with politically left-leaning cities and states early in the COVID-19 pandemic may have exacerbated vaccine hesitancy in right-leaning states of the US. Criticism from outside experts violates rules of communication between social groups (i.e. an ), leading to rejection of messages promoting vaccine safety and efficacy. In two studies, we document the effects of shared geographical group membership for medical expert messages promoting vaccination. We also found evidence that satisfying conversational norms against intergroup criticism reduces message rejection. Specifically, an invitation from ingroup political elites for a doctor to speak reduced the negative effects of unshared group identity.
在 COVID-19 大流行早期，医学专家与政治上倾向左派的城市和州结盟，这可能加剧了美国右派州的疫苗犹豫情绪。来自外部专家的批评违反了社会群体之间的交流规则（即 an ），导致拒绝传递疫苗安全性和有效性的信息。在两项研究中，我们记录了医疗专家发布的促进疫苗接种的信息中，共享地理群体成员身份的影响。我们还发现了一些证据表明，满足反对群体间批评的会话规范可以减少信息的拒绝率。具体来说，来自同组政治精英的邀请，让一位医生发言，可以减少不同组身份认同的负面影响。
