The heritability of cognitive abilities and several psychological traits increases with age, while the influence of the family and social environment decreases. In other words, when it comes to cognitive abilities, nature becomes more important as you get older.
One explanation: As people grow older, they become increasingly in control of their environment, so they begin to choose, change, and create environments that suit their preferences and talents shaped by their genes.
The results of this study by Robert Plomin and his colleagues, titled "Ten Reproducible Findings in Behavioral Genetics," cast great doubt on the popular belief in the existence of so-called. "female and male gender socialization" (WGS and MGS), which supposedly greatly shapes a person's personality.
FGS and MGS can manifest in adolescence (adolescence), but weaken with age, and then your behavior in all environments (from work to family) is largely due to the genes of your maternal and paternal ancestors.
