With just one exception, all of the volumes in Terman’s Genetic Studies of Genius report the results of a longitudinal study of more than a thousand intellectually gifted children. That single exception is Volume II, Cox’s single-authored The Early Mental Traits of Three Hundred Geniuses, which instead was a retrospective study of 301 eminent creators and leaders, using historiometric methods to estimate their IQs (as well as to assess a subset of 100 on 67 character traits). This article discusses how this volume actually fits with the other four volumes in the set. After giving the historical background, discussion turns to the emergence of Cox’s doctoral dissertation. Then comes a narrative of the aftermath, including subsequent contributions by Cox, Terman, and numerous other researchers extending into the 21st century. The article closes by treating the ways that the intellectually gifted and the historic geniuses are not comparable, thus indicating the need for more recent replications and extensions of her work.

高尔顿、特曼、考克斯：天才遗传研究的独特卷 II

除了一个例外，特曼的《天才遗传研究》中的所有卷都报告了对一千多名智力天才儿童进行的纵向研究的结果。唯一的例外是第二卷，考克斯的独著《三百个天才的早期心理特征》，而是对 301 位杰出的创造者和领导者的回顾性研究，使用历史计量方法来估计他们的智商（以及评估 100 67 个性格特征）。本文讨论了该卷如何与该系列中的其他四卷相适应。在给出历史背景之后，讨论转向考克斯博士论文的出现。然后是对后果的叙述，包括考克斯、特曼和许多其他研究人员的后续贡献，这些研究一直延伸到 21 世纪。
