In addition to being a source of valuable nutrients, meat consumption has several negative consequences; for the environment, for animal welfare, and for human health. To persuade people to lower their meat consumption, it is assumed that the personal relevance of the topic of lowering meat consumption is important as it determines how people perceive the quality of the arguments.
In an experimental exploratory field study ( = 139), participants recruited from the general Italian population were randomized to one of the four conditions with a text with pictures on the environmental, animal welfare, or health consequences of meat consumption, or a text on mustard (the control condition). The dependent variables were self-reported consumption of red meat and processed meat after 2 weeks. Personal relevance was assessed in the pre-test with self-reported meat consumption and intention.
The interaction between pre-test meat consumption and condition was significant: In participants who scored high on pre-test meat consumption, the self-reported red meat consumption after 2 weeks in the health argument condition was significantly lower compared to the control condition and the environmental argument condition. The effects of pre-test intention as a moderator were less certain.
The persuasive effects of the different arguments made a difference only in people who ate a relatively high level of meat in pre-test, and the type of arguments made a difference. Although the present outcomes are caused by the specific formulations of the arguments in this study, the results do show that it is relevant to choose the arguments carefully to ensure effectiveness.
肉类消费除了是宝贵营养物质的来源外,还会产生若干负面后果;对环境、动物福利和人类健康而言皆是如此。为了说服人们减少肉类消费,降低肉类消费这一话题的个人相关性被认为很重要,因为它决定了人们如何看待这些论据的质量。
在一项实验性探索性实地研究(n = 139)中,从意大利普通人群中招募的参与者被随机分配到四个条件之一,分别是阅读一篇配有关于肉类消费对环境、动物福利或健康影响图片的文本,或者阅读一篇关于芥末的文本(对照条件)。因变量是两周后自我报告的红肉和加工肉消费量。在预测试中通过自我报告的肉类消费和意愿来评估个人相关性。
预测试肉类消费与条件之间的交互作用显著:在预测试肉类消费得分高的参与者中,与对照条件和环境论据条件相比,健康论据条件下两周后自我报告的红肉消费量显著更低。预测试意愿作为调节变量的影响不太确定。
不同论据的说服效果仅在预测试中肉类摄入量相对较高的人群中产生了差异,而且论据的类型也产生了影响。尽管目前的结果是由本研究中论据的特定表述引起的,但结果确实表明谨慎选择论据以确保有效性是有意义的。
