Cultured meat (also referred to as cultivated, cell-based, or cell-cultured meat) is a novel food technology that is presented as a method of meat production without reliance on large-scale industrial farming. The pro-cultured meat narrative rests, in part, on a moral foundation: cultured meat is purported to alleviate the environmental and animal welfare harms associated with farmed meat. Despite this narrative, no research has examined which moral values underpin attitudes towards cultured meat. To examine this, we surveyed 1861 participants from the United States and Germany about their moral foundations and their attitudes towards cultured meat. In line with predictions, people who more strongly endorse moral values about purity (i.e., had higher scores on the purity subscale of the moral foundations scale) held more negative attitudes towards cultured meat. However, this relationship was much more consistent among participants from the United States than participants from Germany. Against predictions, attitudes towards cultured meat were not reliably associated with the extent to which people focus on harm as a moral foundation. The latter finding was particularly surprising in light of harm-reduction narratives around cultured meat. These findings demonstrate the need for a more nuanced discussion about, and understanding of, consumer concerns around cultured meat and the values that underpin them.
培养肉（也被称为培养的、基于细胞的或细胞培养的肉）是一种新颖的食品技术，被提出作为一种无需依赖大规模工业化养殖的肉类生产方法。支持培养肉的说法部分基于道德基础：培养肉据称可以减轻与养殖肉类相关的环境和动物福利危害。尽管有这种说法，但没有研究探讨哪些道德价值观是培养肉态度的基础。为了检验这一点，我们调查了来自美国和德国的 1861 名参与者，了解他们的道德基础以及对培养肉的态度。符合预测的是，更强烈地支持纯洁道德价值观的人（即，在道德基础量表的纯洁子量表上得分较高）对培养肉的态度更为负面。然而，这种关系在美国参与者中比在德国参与者中更为一致。与预测相反，培养肉的态度与人们将伤害作为道德基础的程度并不可靠相关。鉴于培养肉的减少伤害的说法，后一种发现尤其令人惊讶。这些发现表明，需要更细致地讨论和理解消费者对培养肉的担忧以及支撑这些担忧的价值观。
