Several studies have examined the role of birth order in shaping human personality, but fewer have tested this variable in relation to other pressing issues. We conducted a birth-order study on green consumption, which enabled us to detect a small-to-moderate effect size equivalent to = 0.15 or = 0.30 with sufficient statistical power ( = 335). To capture green consumption, participants indicated their tendency to express the value of environmental protection through purchases and consumption behaviors. Firstborns (vs. laterborns) consistently expressed lower concerns linked to environmental protection in their purchase patterns. While the effect size of this finding was small-to-moderate by conventional standards and in direct contrast to the findings from a recent article on the same topic, these results could still be informative to address challenges associated with climate change considering the number of individuals with siblings in the world and the ease with which birth-order data can be collected.
多项研究探讨了出生顺序在塑造人格方面的作用，但较少有研究将这一变量与其他紧迫问题联系起来进行测试。我们开展了一项关于绿色消费的出生顺序研究，借助该研究，我们在具备足够统计效力（N = 335）的情况下，检测到了相当于f = 0.15或f = 0.30的小到中等效应量。为衡量绿色消费，参与者表明了他们通过购买和消费行为来表达环境保护价值观的倾向。在购买模式方面，长子（女）（相对于后出生的子女）始终表现出与环境保护相关的较低关注度。尽管按照传统标准，这一发现的效应量较小到中等，且与近期一篇关于同一主题的文章的研究结果直接相反，但考虑到全球有兄弟姐妹的个体数量以及收集出生顺序数据的便捷性，这些结果对于应对与气候变化相关的挑战仍可能具有参考价值。
