抽象的。正义是人类进化的基本原则之一，来自亲自我（例如，作为受害者）和亲社会视角（例如，作为观察者、受益者和犯罪者）的正义敏感性对于心理健康和社会互动至关重要。然而，正义敏感性的个体差异在多大程度上受遗传因素和环境因素的影响仍不清楚。本研究以 244 对双胞胎为样本，试图确定遗传因素在正义敏感性个体间差异中发挥作用的程度，以及正义敏感性的不同方面，即亲自我和亲社会观点是否具有共同的遗传基础。结果表明，（1）正义敏感性的所有方面都具有中等遗传性（21-33%），非共享环境因素加上测量误差造成了其余的变异（67-79%）； (2) 正义敏感性的亲社会方面之间的关联是由共同遗传 (rg = .50–.65) 和非共享环境（加上测量误差；re = .24–.65）影响驱动的，而亲自我和亲社会方面之间没有发现显着的遗传联系。目前的研究结果提供了新的证据，表明对不公正的敏感性，特别是对他人痛苦的敏感性，从根本上是基于遗传起源，从而揭示了正义行为的本质和后天方面。
Abstract. Justice is one of the fundamental principles in human evolution, and justice sensitivity from the pro-self (e.g., as a victim) and the prosocial perspective (e.g., as an observer, beneficiary, and perpetrator) matters in mental wellness and social interaction. However, the extent to which individual difference in justice sensitivity is influenced by genetic versus environmental factors remains unclear. Using a sample with 244 twin pairs, the present research attempts to determine the extent to which genetic factors play a role in the inter-individual difference of justice sensitivity as well as whether different facets of justice sensitivity, namely, pro-self and prosocial perspectives, share a common genetic basis. Results showed that (1) all facets of justice sensitivity were moderately heritable (21–33%) and that the non-shared environmental factors plus measurement error accounted for the rest of the variations (67–79%); (2) associations between the prosocial facets of justice sensitivity were driven by common genetic ( rg = .50–.65) and non-shared environmental (plus measurement error; re = .24–.65) influences, whereas no significant genetic link was found between the pro-self and prosocial facets. The current findings provide novel evidence that sensitivity to injustice, especially to others’ suffering, is fundamentally grounded upon genetic origin, thereby shedding light on the nature and nurture aspects of justice behavior.
