Extensive research efforts have been devoted to understanding the nature of Conscientiousness, the only Big Five personality trait that has been robustly linked to professional achievement and longevity. We proposed that Conscientiousness is associated with Personal Belief in a Just World (PBJW), that is, the extent to which an individual believes that her or his efforts will be rewarded. To investigate this proposition, we undertook a meta‐analysis synthesizing past findings regarding the relationship between PBJW and Conscientiousness; we confirmed a positive relationship between the two constructs (r = .16) based on 17 samples and 5,810 individuals. We further proposed a theoretical framework linking PBJW to specific facets of Conscientiousness. A survey of a representative sample of the US population (n = 311) confirmed that PBJW is positively correlated with the specific facets of Self‐efficacy, Achievement‐striving, and Self‐discipline. Internal Locus of Control mediated these associations, elucidating the underlying processes linking PBJW and Conscientiousness.

公正世界和尽职尽责的个人信念：荟萃分析，方面层面的考察和调解模型

大量的研究工作致力于理解尽责性的本质，这是与职业成就和长寿紧密相关的唯一的五个大人格特质。我们提出，尽责与正义世界中的个人信仰（PBJW）相关联，也就是说，个人相信自己的努力会得到回报的程度。为了研究这一命题，我们进行了荟萃分析，综合了以往关于PBJW和尽责性之间关系的发现。我们 基于17个样本和5,810个人证实了两种构建体之间的正相关性（r = .16）。我们进一步提出了一个理论框架，将PBJW与尽职调查的特定方面联系起来。对美国人口代表性样本的调查（n  = 311）证实PBJW与自我效能感，成就追求和自我约束的特定方面呈正相关。内部控制源介导了这些关联，阐明了将PBJW和责任感联系起来的潜在过程。
