Money can take many forms—a coin or a bill, a payment for an automobile or a prize for an award, a piece from the 1989 series or the 2019 series, and so on—but despite this, money is designed to represent an amount and only that. Thus, a dollar is a dollar, in the sense that money is fungible. But when adults ordinarily think about money, they think about it in terms of its source, and in particular, its moral source (e.g., dirty money). Here we investigate the development of the belief that money carries traces of its moral history. We study children ages 5–6 and 8–9, who are sensitive to both object history and morality, and thus possess the component pieces needed to think that a dollar may not be like any other. Across three principal studies (and three additional studies in Appendix S1; N = 327; 219 five‐ and six‐year‐olds; 108 eight‐ and nine‐year‐olds), we find that children are less likely to want money with negative moral history, a pattern that was stronger and more consistent among 8‐ and 9‐year‐olds than 5‐ and 6‐year‐olds. These findings highlight pressing directions for future research that could help shed light on the mechanisms that contribute to the belief that money carries traces of its moral history.

一美元就是一美元 是一美元吗？孩子们对“脏钱”的推理的见解


金钱可以有多种形式——硬币或钞票、汽车付款或奖励、1989 年系列或 2019 年系列的作品等等——但尽管如此，金钱的设计目的是代表一定数量仅此而已。因此，一美元就是一美元，因为货币是可以互换的。但是，当成年人通常思考金钱时，他们会从其来源，特别是其道德来源（例如，脏钱）来思考它。在这里，我们调查了“金钱带有其道德历史痕迹”这一信念的发展。我们研究 5-6 岁和 8-9 岁的儿童，他们对物体历史和道德都很敏感，因此拥有认为一美元可能与其他美元不同所需的组成部分。通过三项主要研究（以及附录 S1 中的三项附加研究； N = 327；219 名 5 岁和 6 岁儿童；108 名 8 岁和 9 岁儿童），我们发现孩子不太可能想要金钱道德史，这种模式在 8 岁和 9 岁的孩子中比 5 岁和 6 岁的孩子更强烈、更一致。这些发现凸显了未来研究的紧迫方向，有助于阐明货币带有道德历史痕迹这一信念的机制。
