Lower-income individuals are frequently criticized for their consumption decisions; this research examines why. Eleven preregistered studies document systematic differences in permissible consumptioninterpersonal judgments about what is acceptable (or not) for others to consume-such that lower-income individuals' decisions are subject to more negative and restrictive evaluations. Indeed, the same consumption decisions may be deemed less permissible for a lower-income individual than for an individual with higher or unknown income (studies 1A and 1B), even when purchased with windfall funds. This gap persists among participants from a large, nationally representative sample (study 2) and when testing a broad array of "everyday" consumption items (study 3). Additional studies investigate why: The same items are often perceived as less necessary for lower- (versus higher-) income individuals (studies 4 and 5). Combining both permissibility and perceived necessity, additional studies (studies 6 and 7) demonstrate a causal link between the two constructs: A purchase decision will be deemed permissible (or not) to the extent that it is perceived as necessary (or not). However, because-for lower-income individuals-fewer items are perceived as necessary, fewer are therefore socially permissible to consume. This finding not only exposes a fraught double standard, but also portends consequential behavioral implications: People prefer to allocate strictly "necessary" items to lower-income recipients (study 8), even if such items are objectively and subjectively less valuable (studies 9A and 9B), which may result in an imbalanced and inefficient provision of resources to the poor.
低收入个人经常因其消费决策而受到批评;本研究探讨了原因。十一项预先注册的研究记录了可接受消费的人际判断中的系统性差异,即对于他人可接受(或不可接受)的消费标准——以至于低收入个人的决策受到更多负面和限制性的评价。事实上,同样的消费决策可能被认为对低收入个人来说比高收入或未知收入的个人更不可接受(研究 1A 和 1B),即使是用意外之财购买的。这一差距在来自大型全国代表性样本的参与者中仍然存在(研究 2),并且在测试广泛的“日常”消费项目时也存在(研究 3)。其他研究探讨了原因:同样的物品通常被认为对低收入个人而言没有那么必要(相对于高收入个人)(研究 4 和 5)。结合可接受性和感知必要性,其他研究(研究 6 和 7)证明了这两个结构之间的因果关系:购买决策的可接受性(或不可接受性)取决于其被认为是必要的(或不必要的)程度。然而,由于对于低收入个人而言,较少的物品被认为是必要的,因此,较少的物品因此在社会上被允许消费。这一发现不仅暴露了一个充满矛盾的双重标准,而且预示着具有后果的行为影响:人们更愿意将严格的“必要”物品分配给低收入接受者(研究 8),即使这些物品在客观和主观上价值较低(研究 9A 和 9B),这可能导致对穷人资源的不平衡和低效配置。
