摘要

摘要正义是人类进化的基本原则之一,从亲自我(如作为受害者)和亲社会(如作为观察者、受益者和肇事者)角度出发的正义敏感性在心理健康和社会互动中起着重要作用。然而,司法敏感性的个体差异在多大程度上受遗传因素与环境因素的影响尚不清楚。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差异中的作用程度,以及正义敏感性的不同方面,即亲自我观点和亲社会观点是否具有共同的遗传基础。结果表明:(1)各方面的公正敏感性均为中等遗传变异(21-33%),其余变异由非共享环境因素和测量误差引起(67-79%);(2)亲社会方面的正义敏感性受共同遗传误差(rg = 0.50 ~ 0.65)和非共同环境误差(加上测量误差)驱动;Re = 0.24 - 0.65)的影响,而亲自我和亲社会方面之间没有发现显著的遗传联系。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,从根本上建立在基因起源的基础上,从而揭示了正义行为的本质和培养方面。

Heritability of Justice Sensitivity
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.

期刊介绍: Researchers, teachers, and students interested in all areas of individual differences (e.g., gender, temperament, personality, intelligence) and their assessment in human and animal research will find the Journal of Individual Differences useful. The Journal of Individual Differences publishes manuscripts dealing with individual differences in behavior, emotion, cognition, and their developmental aspects. This includes human as well as animal research. The Journal of Individual Differences is conceptualized to bring together researchers working in different areas ranging from, for example, molecular genetics to theories of complex behavior.
