本文研究了隐喻在疫苗接种推理任务中的作用，特别是在可撤销推理中。我们假设隐喻和可废止推理都可以通过预测可能的失败条件来让人们理解疫苗接种是一种重要的集体健康现象。我们假设，扩展隐喻可以提高信息的论证和交际效果。我们设计了一项实证研究来检验我们的主要假设：参与者（N = 196，78%女性;平均年龄= 27.97岁，SDage = 10.40）被呈现一个关于疫苗接种的文本，根据不确定与安全的推理场景，以字面或隐喻的方式描述。研究结果证实，可废止的推理是相关的文本的交际效果和扩展的隐喻增强了整体的交际效果的消息，在可理解性，说服力，感知的安全感，控制的感觉，在专业知识和吸收专家的意见集体信任的健康状况。然而，研究结果表明，这种效果是显着的细微差别的类型的可废止的推理，特别是在参与者的信任的专业知识和承诺的专家的意见。沟通和可撤销的推理能力都需要增强对免疫接种的信任，在个人和集体层面可能会产生不同的结果。
The paper investigates the impact of the use of metaphors in reasoning tasks concerning vaccination, especially for defeasible reasoning cases. We assumed that both metaphor and defeasible reasoning can be relevant to let people understand vaccination as an important collective health phenomenon, by anticipating possible defeating conditions. We hypothesized that extended metaphor could improve both the argumentative and the communicative effects of the message. We designed an empirical study to test our main hypotheses: participants (N = 196, 78% females; Meanage = 27.97 years, SDage = 10.40) were presented with a text about vaccination, described in either literal or metaphorical terms, based on uncertain vs. safe reasoning scenarios. The results of the study confirmed that defeasible reasoning is relevant for the communicative impact of a text and that an extended metaphor enhances the overall communicative effects of the message, in terms of understandability, persuasion, perceived safety, and feeling of control over the health situation, collective trust in expertise and uptake of experts' advice. However, the results show that this effect is significantly nuanced by the type of defeasible reasoning, especially in the case of participants' trust in expertise and commitment to experts' advice. Both communicative and defeasible reasoning competences are needed to enhance trust in immunization, with possible different outcomes at an individual and collective level.
