It's evident! Identifying frames of evidence as used in science TV programs and testing their effectson beliefs

科学电视节目中出现的医学问题或多或少都有证据支持。在一份报告中，科学记者选择不同的科学证据来源（例如，实验研究、案例研究或专家意见），并代表不同的论点。科学节目中描述科学医学问题的证据的方式会影响接受者对这些问题的看法。本研究采用Dempster-Shafer证据理论（1976）进行了标准化的内容分析。首先确定证据框架，然后通过实验检验，以确定这些框架是否以及如何影响接受者的信念。创建了一个映射形式-抽象证据框架的动态效果的模型，其中关于给定问题的预先存在的信念的作用是讨论的重点。

Medical issues presented on science TV programs are depicted more or less supported by evidence. In one report science journalists choose different sources of scientific evidence (e.g., experimental studies, case studies, or expert opinions), and represent different argumentations.The way that the evidence for scientific medical issues is depicted in science programs impacts recipients¿ beliefs about these issues. In the present study, a standardized content analysis was conducted, applying the Dempster-Shafer theory of evidence (1976). Frames of evidence were first identified, and then examined experimentally to determine whether and how these frames influenced the beliefs of recipients. A model mapping the dynamic effects of formal-abstract frames of evidence was created, with the role of preexisting beliefs about given issues being a point of emphasis in the discussion.
