Why Doesn't Childhood Association Always Inhibit Sexual Attraction?

引起哲学家、神学家以及社会和生物科学家注意的为数不多的问题之一是近亲之间几乎普遍禁止性关系的起源。直到几年前，核心问题是：禁令是为了保护人类不受与近亲交配和结婚的自然倾向的影响，还是源于儿童早期交往引起的性厌恶？换句话说，乱伦禁忌是否压制或表达了一种自然的人类倾向？来自以色列和台湾的研究证据表明，从小一起抚养的孩子会对性关系产生反感。大多数科学家一致认为，近亲繁殖的危险是导致这种现象的最终原因。但直接原因是这个项目的主题。这个项目的主要目的是研究台湾的未成年婚姻(新娘从小作为新郎的兄弟姐妹抚养长大)。日本殖民政府编制的户口簿使重建以次要方式结婚的夫妇所养育的家庭成为可能，并确定他们的父母是否以次要方式结婚以及结果如何。这创造了确定早期关联是可遗传的什么的可能性。这项研究的更广泛的含义涉及到我们对人类性行为的总体理解。乱伦不太可能是人类性行为的一个孤立方面。关于近亲之间的性吸引力是否受到抑制的证据将会引起普遍的兴趣，因为它肯定会对我们对性吸引力的总体理解产生影响。

One of the few questions that have engaged the attention of philosophers and the theologians as well as social and biological scientists is the origins of the nearly universal prohibition on sexual relations between close relatives. Until only a few years ago the central question was: Is the prohibition constructed to protect human beings from a natural inclination to mate and marry their close relatives or is the prohibition rooted in a sexual aversion aroused by early childhood association? In other words, does the incest taboo repress or express a natural human tendency? Evidence from studies in Israel and Taiwan has shown that children reared together from an early age develop an aversion to sexual relations. Most scientists agree that the ultimate cause is the dangers of inbreeding. But the proximate cause is the subject of this project. The primary purpose of this project is to examine Taiwanese minor marriages (where the bride is reared from a young age as a sibling of the groom). Household registers compiled by the Japanese colonial government make it possible to reconstruct the families in which couples married in the minor fashion were reared and determine whether or not their parents married in the minor fashion and with what result. This creates the possibility of determining what it is about early association that is heritable.Broader impact. The broader implication of the research concerns our understanding of human sexuality in general. It is very unlikely that incest is an isolated aspect of human sexuality. Evidence concerning the conditions that do or do not inhibit sexual attractions among close relatives will be of general interest because it is certain to have implications for our understanding of sexual attraction in general.
