SAEDNEWS: Researchers Found That Personality Traits Are More Influential in Having Children
Researchers at the Queensland University of Technology in Australia reported that men who exhibit a range of personality traits—such as emotionality, extraversion, agreeableness, and conscientiousness—tend to have more children.
Historically, competition has been a driver of greater success for both men and women, leading to achievements in careers, sports, arts, the ability to acquire and provide resources, and ultimately survival. New study findings suggest that personality traits can also influence the number of children a person has.
In this study, participants answered a wide range of social and demographic questions and completed the Big Five personality test (BIG 5). A total of 3,000 men and 1,500 women were included in the research.
Experts identified key personality differences between the sexes and their relationship with having more children.
The test measures personality variables based on five dimensions: neuroticism, extraversion, agreeableness, openness to experience, and conscientiousness.
However, there is still limited information on the advantages or disadvantages of these traits regarding having more children, and science has yet to fully understand how personality and reproductive behaviors are connected.

The results showed that a combination of specific traits in men—extraversion, agreeableness, conscientiousness, and diligence—correlates with having more children. Additionally, among the Big Five traits, extraversion was linked to a higher number of children in men, while in women, only higher agreeableness was associated with having more children.
Further analysis is needed to fully understand these patterns in women. The study was published in the journal Personality and Individual Differences.
