Prior research has found that people’s choices in economic games are often only modestly related to their prosocial personality traits and to mundane prosocial behaviors. The present article reviews the recent literature showing that the strength of these relationships depends on the level of aggregation. Specifically, we demonstrate an increase in behavioral consistency after horizontal aggregation (across multiple game types), vertical aggregation (across multiple game variants), and a combination thereof. Moreover, we show that aggregation increases the magnitude of the relationships of game behavior with prosocial personality and mundane prosocial behavior. These findings illustrate that economic games can genuinely capture a core facet of human prosociality — but that their capacity for doing so is greater when multiple game behaviors are considered.

先前的研究发现，人们在经济博弈中的选择通常只与他们的亲社会人格特征和世俗的亲社会行为适度相关。本文回顾了最近的文献，表明这些关系的强度取决于聚合水平。具体来说，我们展示了水平聚合（跨多种游戏类型）、垂直聚合（跨多种游戏变体）及其组合后行为一致性的提高。此外，我们表明聚合增加了游戏行为与亲社会人格和世俗的亲社会行为之间的关系。
