While uncertainty is central to science, many fear negative effects of communicating scientific uncertainties to the public, though research results about such effects are inconsistent. Therefore, we test the effects of four distinct uncertainty frame types (deficient, technical, scientific, consensus) on three outcomes (belief, credibility, behavioral intentions) across three science issues (climate change, GMO food labeling, machinery hazards) with an experiment using a national sample (N = 2,247) approximating U.S. census levels of age, education, and gender. We find portraying scientific findings using uncertainty frames usually does not have significant effects, with an occasional exception being small negative effects of consensus uncertainty.

不确定性框架在三个科学传播主题中的影响

虽然不确定性是科学的核心，但许多人担心向公众传达科学不确定性会产生负面影响，尽管关于这种影响的研究结果并不一致。因此，我们通过实验测试了四种不同的不确定性框架类型（缺陷、技术、科学、共识）对三个科学问题（气候变化、转基因食品标签、机械危害）的三个结果（信念、可信度、行为意图）的影响使用接近美国人口普查年龄、教育和性别水平的全国样本 (N = 2,247)。我们发现使用不确定性框架描述科学发现通常不会产生显着影响，偶尔的例外是共识不确定性的小负面影响。
