Human populations differ reliably in the degree to which people favor family, friends, and community members over strangers and outsiders. In the last decade, researchers have begun to propose several economic and evolutionary hypotheses for these cross-population differences in parochialism. In this paper, we outline major current theories and review recent attempts to test them. We also discuss the key methodological challenges in assessing these diverse economic and evolutionary theories for cross-population differences in parochialism.
在人们对家人、朋友和社区成员相较于陌生人和局外人的偏爱程度上,不同人群存在显著差异。在过去十年中,研究人员已开始针对这些群体间狭隘主义的差异提出若干经济和进化假说。在本文中,我们概述了当前的主要理论,并回顾了近期对这些理论进行检验的尝试。我们还讨论了在评估这些关于群体间狭隘主义差异的多样经济和进化理论时所面临的关键方法挑战。
