Agreeableness impacts people and real-world outcomes. In the most comprehensive quantitative review to date, we summarize results from 142 meta-analyses reporting effects for 275 variables, which represent N > 1.9 million participants from k > 3,900 studies. Arranging variables by their content and type, we use an organizational framework of 16 conceptual categories that presents a detailed account of Agreeableness’ external relations. Overall, the trait has effects in a desirable direction for 93% of variables (grand mean ρ¯M=.16${\overline{\rho }}_M=.16$${\overline{\rho }}_M=.16$). We also review lower order trait evidence for 42 variables from 20 meta-analyses. Using these empirical findings, in tandem with existing theory, we synthesize eight general themes that describe Agreeableness’ characteristic functioning across variables: self-transcendence, contentment, relational investment, teamworking, work investment, lower results emphasis, social norm orientation, and social integration. We conclude by discussing potential boundary conditions of findings, contributions and limitations of our review, and future research directions.

宜人性会影响人和现实世界的结果。在迄今为止最全面的定量回顾中，我们总结了 142 项荟萃分析的结果，报告了 275 个变量的影响，这些变量代表了来自k > 3,900 项研究的N > 190 万参与者。根据变量的内容和类型排列变量，我们使用了一个包含 16 个概念类别的组织框架，详细描述了宜人性的外部关系。总体而言，该特征对 93% 的变量（总平均ρ¯米= 。16${\overline{\rho }}_{米}=.16$${\overline{\rho }}_M=.16$）。我们还审查了来自 20 个荟萃分析的 42 个变量的低阶特征证据。使用这些实证研究结果，结合现有理论，我们综合了描述宜人性跨变量特征功能的八个一般主题：自我超越、满足、关系投资、团队合作、工作投资、较低的结果强调、社会规范导向和社会整合. 最后，我们讨论了研究结果的潜在边界条件、我们的评论的贡献和局限性，以及未来的研究方向。
