Science Shows Having A Sister Makes You A Better Person


I have a sister. We get along great. As kids though, we fought and had our growing pains. That’s normal because we still loved each other. Science has finally caught up with the truth that having an older or younger sister makes your life better. So hooray for sisters!

The results of the 2010 study were published in The Journal of Family Psychology. It involved examining 400 families with multiple siblings; one of whom was between the ages of 10-14. Having a sister promoted positive mental health in their siblings.

The results also showed these brothers and sisters also had a greater capacity to empathize, communicate, and resolve conflicts. Laura Padilla-Walker, a professor in the university’s School of Family Life and the study’s lead  author, said that even with all the fighting that may occur, “as long as they have affection, the  positive will win out.”


When siblings fight, they must learn to regulate emotions. This is a crucial skill for later in life. And even though sisters and siblings argue, it’s an undeniable truth that life with a brother or sister is less lonely. It’s not shocking that girls talk and are more communicative than boys. If you have a sister, you’re more likely to talk out life’s problems.

There’s good news for the ladies too. Boys who grew up with sisters are better communicators with women in general. What’s most interesting about the study found that after the siblings parents have passed away, sisters do more to keep the family together.

So despite the minor hiccups or arguments you might have with your siblings, they’re just small bumps in the road. Remember your siblings will be with you through your entire life. Keep them close and your relationship strong.
