Psychological traits display substantial variation worldwide. These psychological variations could be explained by the intensity of kinship ties which, we hypothesize, depends on the reception of innovations that gradually complexified family organizations. These innovations originated from several centers across the world that also spread other crucial novelties such as agriculture. Less exposed to these family innovations, areas far from centers of innovation should exhibit lower kinship intensity. Indeed, we show that distance to innovation centers is strongly associated with kinship intensity. This distance is also associated with psychological traits especially outside Western Europe in which exposure to the Church seems to play an additional role.
心理特征在全球范围内存在显著差异。这些心理差异可以用亲属关系的紧密程度来解释，我们假设亲属关系的紧密程度取决于创新的接受程度，而创新逐渐使家庭组织复杂化。这些创新起源于世界各地的几个中心，也传播了其他关键的新颖性，如农业。在远离创新中心的地区，这些家庭创新的接受程度较低，亲属关系的强度应该较低。事实上，我们发现，与创新中心的距离与亲属关系的强度密切相关。这种距离也与心理特征有关，特别是在欧洲以外的地区，在那里，教会的影响似乎起着额外的作用。
