Markus Jokela and Liisa Keltikangas-Jarvinen examined whether four subcomponents of type-A , including leadership, being hard-driving, eagerness, and , assessed among adolescents predicted the likelihood of having in later life.

Adolescents who scored high on personality traits assessing leadership tendencies were more likely to have children as adults 18 years later, regardless of education level.

The findings suggest that status striving may be important for even in modern humans when the relevant traits are measured at the right level - not as educational diplomas or high-status occupations, but as having a dominant personality.

"Our study should lead evolutionary-oriented researchers to reconsider some earlier assumptions regarding the role of in explaining modern fertility behavior," the authors conclude.
