为了研究自闭症疫苗争议的平衡陈述如何影响疫苗风险的判断，我们随机分配了327名参与者，这些参与者发表了支持和反对自闭症疫苗联系的平衡声明，仅antilink声明，仅prolink声明或不相关的信息。处于平衡状态的读者不太确定疫苗不会导致自闭症，更有可能相信专家在这个问题上存在分歧。均衡覆盖和确定性之间的关系是由医学专家对自闭症与疫苗之间潜在联系的看法所介导的。我们讨论了这些发现的理论和实践意义。
To investigate how balanced presentations of the autism-vaccine controversy influence judgments of vaccine risk, we randomly assigned 327 participants to news articles that presented balanced claims both for and against an autism-vaccine link, antilink claims only, prolink claims only, or unrelated information. Readers in the balanced condition were less certain that vaccines did not cause autism and more likely to believe experts were divided on the issue. The relationship between exposure to balanced coverage and certainty was mediated by the belief that medical experts are divided about a potential autism-vaccine link. We discuss theoretical and practical implications of these findings.
