Biographical determinants of achieved eminence: a multivariate approach to the Cox data

Ranked eminence of creators and leaders was hypothesized to be a function of both substantive (developmental and productive) variables and methodological artifacts. Cox's sample of 301 geniuses was reexamined using multiple-regression techniques. The results indicated that ranked eminence is (a) a curvilinear inverted-U function of education for creators but a negative linear function for leaders, (b) a positive linear function of versatility for leaders only, and (c) a curvilinear U-shaped function of life span for creators but a "backwards-J" function for leaders. Although creators are more intelligent than leaders, the correlation that Cox found between intelligence and ranked eminence was shown to be an artifact of data reliability and, especially, a timewise sampling bias. It was also shown that father's status has no direct impact on ranked eminence.
