Concerns about cuckoldry are a dominant theme in evolutionary studies of mating, frequently used to explain sex differences in reproductive strategies. However, studies in nonhuman species have shown that cuckoldry can be associated with important benefits. These insights have not been well integrated with the human literature, which continues to focus on anticuckoldry tactics and negative repercussions for men. I evaluate two key assumptions central to human models of cuckoldry: (1) men are being tricked into investing in nonbiological offspring and (2) investment in nonbiological offspring is wasted. The ethnographic data on fatherhood shows that the concepts of pater and genitor are complex and locally constructed ideas that often include explicit knowledge of extra-pair paternity, countering the idea that nonpaternity results from trickery. Furthermore, rather than being a “waste,” paternity loss can be associated with important gains for men, helping to explain why men invest in nonbiological offspring.

戴绿帽子的难题

对戴绿帽的担忧是交配进化研究的一个主导主题，经常被用来解释生殖策略中的性别差异。然而，对非人类物种的研究表明，戴绿帽子可以带来重要的好处。这些见解尚未与人类文学很好地结合起来，人类文学继续关注反通奸策略和对男性的负面影响。我评估了人类通奸模型的两个关键假设：（1）男人被欺骗而对非生物后代进行投资；（2）对非生物后代的投资被浪费了。关于父亲身份的人种学数据表明，父亲和父亲的概念是复杂的、本地化的观念，通常包括对配对外父亲身份的明确了解，反驳了非父亲身份源于欺骗的观点。此外，失去亲子关系并不是一种“浪费”，反而可以为男性带来重要的收益，这有助于解释为什么男性投资于非生物后代。
