Personality and reproductive success

The reproductive success of both men and women is influenced by our personality traits, according to the paper
"Personality and reproductive success in a high-fertility human population"

Alexandra Alvergne, Markus Jokelac, and Virpi Lummaaa

The study, found that women with higher levels of neuroticism and more extravert men, are likely to give birth to a larger number of children in societies with traditionally high birth rates.

Dr Virpi Lummaa said: "Our results show that personality predicts family size differently in men and women, and those men with largest families have personality aspects different from the women with the largest families. Gaining understanding of such individual-level determinants of reproductive decisions helps in the current debate on the role of individual versus social factors in explaining recent fertility changes around the world."
