Abstract

Friendship is a recurring feature of human sociality. Extant evidence has highlighted several axes upon which the formation and maintenance of friendships rest, and has emphasised the importance of market-like mechanisms and preferential assortment in such dynamics. Such evidence has emerged from qualitative ethnographic descriptions, and observational or experimental case studies in relatively homogeneous samples from Western and industrialised settings. Here, we provide one of the first empirical evaluations of the structure of friendship networks in a rural subsistence setting. We collected individual-level friendship network data, and detailed economic and demographic information from individuals in four communities in rural Colombia (N = 470). We analyse these data using a combined social relations and stochastic block model. Our results highlight the importance of preferential assortment on the basis of several socio-demographic traits in all study communities. The extent to which friendship and social support networks overlap appears to vary considerably across communities, with greater overlap being observed in more impoverished areas. Similarly, the extent of wealth homophily was greater in more impoverished areas. Such findings suggest that variation in the axes upon which friendship rests may be affected by community-level variation in economic and demographic composition.

哥伦比亚农村地区的友谊和合作伙伴选择
友谊是人类社会中反复出现的特征。现存的证据强调了友谊的形成和维持所依赖的几个轴,并强调了市场机制和这种动态中的优先分类的重要性。这些证据来自定性的人种志描述,以及来自西方和工业化环境的相对同质样本的观察性或实验性案例研究。在这里,我们提供了农村生存环境下友谊网络结构的首批实证评估之一。我们收集了来自哥伦比亚农村四个社区的个人层面的友谊网络数据,以及详细的经济和人口信息(N = 470)。我们使用结合社会关系和随机块模型来分析这些数据。我们的研究结果强调了在所有研究社区中基于几个社会人口特征的优先分类的重要性。友谊和社会支持网络重叠的程度在不同的社区似乎差别很大,在更贫困的地区,重叠的程度更大。同样,在更贫困的地区,财富同质的程度也更大。这些发现表明,友谊所依赖的轴心的变化可能受到社区经济和人口构成变化的影响。

期刊介绍: Evolution and Human Behavior is an interdisciplinary journal, presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior. It is primarily a scientific journal, but submissions from scholars in the humanities are also encouraged. Papers reporting on theoretical and empirical work on other species will be welcome if their relevance to the human animal is apparent.
