背景：几项实验室研究表明，许多人倾向于潜在的有害遗漏，而不是危害较小的行为。作者研究了这种遗漏偏见在父母决定是否给孩子接种百日咳疫苗时所起的作用。方法：向一本杂志的订阅者发出200份邮寄调查问卷，该杂志发表了赞成和反对接种百日咳疫苗的文章。受试者被问及他们对疫苗和疾病的看法，以及他们是否已经或计划为自己的孩子接种疫苗，并向他们提供测试项目，以确定他们推理中的遗漏偏见。结果：103名受试者(52%)回答了调查。报告说他们不会或不会允许他们的孩子接种疫苗的受访者(n=43；41%)更有可能认为接种疫苗比不接种更危险(p<；0.001)。他们也更有可能表现出遗漏偏见(p=0.004)，保持他们对疫苗危险的既定信念不变。结论：遗漏偏见在决定不接种百日咳疫苗方面发挥了作用，而不是对接种风险的信念所起的作用。
Background: Several laboratory studies have suggested that many people favor potentially harmful omissions over less harmful acts. The authors studied the role of this omission bias in parents' decisions whether to vaccinate their children against pertussis. Methods: Two hundred mail surveys were sent to subscribers to a magazine that had published articles favoring and opposing pertussis vaccination. Subjects were asked about their beliefs about the vaccine and the disease, and whether they had vaccinated their own children or planned to, and they were given test items to identify omission bias in their reasoning. Results: One hundred and three subjects (52%) responded to the survey. Respondents who reported they did not or would not allow their children to be vaccinated (n = 43; 41%) were more likely to believe that vaccinating was more dangerous than not vaccinating (p < 0.001). They were also more likely to exhibit omission bias (p = 0.004), holding constant their stated beliefs about the danger of the vaccine. Conclusions: Omission bias plays a role in decisions not to vaccinate with pertussis vaccine, beyond the role played by belief about the risk of vaccination.
