Researcher Feifei Bu said: “Educational disparities exist not only between families but also within families.
“It is interesting that we observe a distinct firstborn advantage in education even though parents in modern society are more likely to be egalitarian in treating their children.”
Having a sister makes you a better, kinder, more confident person
Another study by Brigham Young University found that sisters gave siblings better mental health.
395 families with more than one child, who were at least between the ages of 10 and 14, were examined as part of the study, which was published in the Journal of Family Psychology.
Researchers looked into the dynamics between each family then followed up a year later. They found that having a sister, older or younger, helps you from feeling lonely, self-conscious, afraid, unloved and guilty.
“What we know suggests that sisters play a role in promoting positive mental health, and later in life they often do more to keep families in contact with one another after the parents pass,” says Alex Jensen, assistant professor in the School of Family Life at Brigham Young University.
“They help you develop social skills, like communication, compromise and negotiation. Even sibling conflict, if it is minor, can promote healthy development.”
