Parents may believe they treat all their children equally, but a new study indicates that sons and daughters are raised in distinct ways. Researchers found that daughters are more likely to receive advice on dating and relationships, along with increased protection and financial support. Conversely, sons are reportedly encouraged to be competitive, receive assistance with sports, and are afforded more sexual freedom.
The study, published in the journal Human Nature, surveyed 105 adults about the types of care they received as children. The findings revealed 73 distinct parenting behaviors that fell into 13 categories, showing significant gender differences in how children are raised.
Parenting roles also appear to differ between mothers and fathers. Fathers were observed to favor spending time practicing sports with their sons and teaching them practical or mechanical skills. Mothers, on the other hand, dedicated more time to providing emotional support, relationship advice, and general life guidance to their daughters.
Researchers suggest these differences stem from habits inherited from ancestors, evolving when boys and girls faced distinct challenges. To maximize their children's chances of success, parents historically invested differently based on gender. Sid Dougan, a PhD student at the University of Texas at Austin and lead author of the study, explained that while men and women have faced common adaptive challenges, certain challenges disproportionately affected one sex over the other, impacting survival and reproductive success.
For instance, sons' reproductive success in evolutionary history was more heavily tied to physical competition, status, hunting, and warfare. Parents who helped prepare their sons for these demands may have passed on their genes more effectively, leading natural selection to favor psychological mechanisms that motivated such investment patterns. This could explain why both mothers and fathers encouraged competitiveness and athletics in sons.
Women, conversely, faced a greater evolutionary risk for poor partner choice. Because males could historically have children with multiple females while females were limited to one partner at a time, parents who invested more in helping daughters navigate relationship challenges may have been more successful over evolutionary periods.
While previous studies have found similar overall amounts of care for sons and daughters, this research highlights differences in the type of parental effort. The study acknowledges its limitations, noting the sample was relatively small and predominantly comprised individuals from white, suburban American households. Future research aims to replicate the study with larger cohorts and in different cultural contexts, such as small-scale hunter-gatherer societies, to further explore these trends.
