Does information about how other people feel about COVID-19 vaccination affect immunization intentions? We conducted preregistered survey experiments in Great Britain (5,456 respondents across 3 survey waves from September 2020 to February 2021), Canada (1,315 respondents in February 2021), and the state of New Hampshire in the United States (1,315 respondents in January 2021). The experiments examine the effects of providing accurate public opinion information to people about either public support for COVID-19 vaccination (an injunctive norm) or public beliefs that the issue is contentious. Across all 3 countries, exposure to this information had minimal effects on vaccination intentions even among people who previously held inaccurate beliefs about support for COVID-19 vaccination or its perceived contentiousness. These results suggest that providing information on public opinion about COVID vaccination has limited additional effect on people's behavioral intentions when public discussion of vaccine uptake and intentions is highly salient.
关于其他人对新冠疫苗接种的看法的信息会影响接种意愿吗？我们在英国（2020年9月至2021年2月的3次调查浪潮中共有5456名受访者）、加拿大（2021年2月有1315名受访者）和美国新罕布什尔州（2021年1月有1315名受访者）进行了预先注册的调查实验。这些实验检验了向人们提供关于公众对新冠疫苗接种的支持（一种指令性规范）或公众认为该问题存在争议的准确民意信息的效果。在所有这三个国家，即使在那些之前对新冠疫苗接种的支持或其可感知的争议性持有不准确看法的人群中，接触这些信息对接种意愿的影响也微乎其微。这些结果表明，当关于疫苗接种率和意愿的公众讨论非常突出时，提供关于新冠疫苗接种的民意信息对人们的行为意愿的额外影响有限。
