Ideas and Contributions

Catharine Cox entered the Stanford’s graduate program in psychology about the time that her mentor Terman was beginning his ambitious longitudinal study of intellectually gifted children. Because this project did not afford her with the suitable opportunity for a dissertation subject, she proposed a complementary investigation. Whereas Terman’s inquiry was psychometric and prospective, Cox would conduct a study that was historiometric and retrospective. In particular, she would estimate IQ scores for highly eminent but deceased creators and leaders and then show that these scores correlated with eminence measures that J. M. Cattell (1903) had previously provided. Just one year after publishing the Stanford-Binet Intelligence Scale Terman (1917) had already shown how an IQ score might be computed for a historical figure, in his case assigning an IQ of near 200 to Francis Galton.

CoxCox’s approach was extremely conscientious and methodical. Using more than 3,000 biographical sources she carefully compiled developmental histories for 301 geniuses, and then she and a team of independent raters – including Terman and Florence Goodenough – used these data to derive the IQ estimates. In addition, she showed that estimated IQ correlated with achieved eminence. Furthermore, for a subset of 100 geniuses she computed ratings on 67 character traits. On the basis of these scores she was able to conclude that motivation, determination, and persistence were also critical to high achievement. The resulting doctoral thesis was sufficiently impressive that Terman had it published as Volume 2 in his Genetic Studies of Genius. Not only was this the only volume that did not involve the longitudinal study of his “Termites,” but it is also the only volume that did not include Terman as an author or co-author. At 842 printed pages, it can easily be considered the most ambitious historiometric investigation ever published. Moreover, many of her key findings have been replicated in subsequent research.  

Unfortunately, Cox was soon diverted from this work by (a) her collaboration with Terman on a masculinity-femininity measure and (b) her marriage to Walter Miles (a recent widower with two teenagers). She also started publishing under her married name Miles rather than Cox. However, a decade later she returned to the historic geniuses that were the subject of her thesis. Miles and Wolfe (1936) specifically scored the geniuses on early mental and physical health. Their aim was to show that intellectual giftedness was also positively associated with both mental and physical well-being.
