Dominant People More Likely to Reproduce

Mar 27, 2009
Men and women with socially dominant traits have better chances for reproductive success, a new study claims.

The research conducted by Markus Jokela and Liisa Keltikangas-Jarvinen from the University of Helsinki studied teenagers' personality traits, including those that are often referred to as type-A personality characteristics. People with type-A personality are often described as aggressive, competitive, energetic and dominant.

The findings of the study showed that teenagers with dominant characteristics were more likely to have children 18 years later, regardless of their educational level.

The results imply that reproductive success can be closely connected to a person's character and determined people may have better chances to succeed not only in career but also in reproduction.

The researchers say that further studies are needed to re-evaluate the importance of evolutionary psychology in modern fertility.

The study was published in the Journal of Personality.
