智力差异的遗传决定：对一起和分开抚养的同卵双胞胎的研究。

在对精神遗传的各个方面进行的一系列研究中，对所谓的“同卵”双胞胎进行了深入的研究。所审查的病例主要分为两组：第一，那些在父母家中一起长大的人;第二，那些在婴儿早期就分开、分开长大的人。对于后者，尽管环境条件存在很大差异，但与学校成绩不同，智力的相关性被证明是惊人的高。有人认为，这意味着“智能”，当充分评估，在很大程度上取决于遗传体质。来自其他群体（异卵双胞胎、一起长大和分开长大的兄弟姐妹、第一和第二堂兄弟姐妹以及其他相关对）的补充相关证实了这一结论。
In the course of a series of investigations into various aspects of mental inheritance an intensive study has been made of so-called ‘identical’ twins. The cases examined fall into two main groups: first, those reared together in their parents' homes; secondly, those separated in early infancy, and brought up apart. With the latter, despite wide differences in environmental conditions, the correlations for intelligence, unlike those for school attainments, prove to be surprisingly high. It is argued that this implies that ‘intelligence’, when adequately assessed, is largely dependent on genetic constitution. Supplementary correlations from other groups (dizygotic twins, siblings reared together and apart, first and second cousins, and other related pairs) confirm this conclusion.
