Are You Smarter? Experts Found These 3 Key Differences Between Older and Younger Siblings

Are You Smarter? Experts Found These 3 Key Differences Between Older and Younger Siblings

Sexual orientation, physical wellbeing and intelligence are all potentially influenced by when you were born into your family.

Siblings have long tried to sort out their differences. Rivalry amongst brothers and sisters seems like it’s more common than peaceful partnerships, when it comes to most families. You would never say two siblings are exactly the same.

But just how different can they be, and how much is nature versus nurture?

A new study done at the University of Leipzig has some answers. Birth order, it’s been found, actually does seem to matter. Of course, the conclusions drawn from the study can’t necessarily be applied across the board and every family is unique. There are some generalities that are interesting, though.

Older siblings have been found to be slightly smarter than younger siblings. Intelligence decreases as you go down the line, researchers say, and it’s thought to be affected by the social status granted to the older siblings. But the youngest siblings are more likely to be healthier than their older counterparts. Younger siblings have a reduced risk of becoming diabetic. And strangely, they’re more likely to be gay.

The study analyzed 20, 000 participants from the UK, United States and Germany. In addition to the factors above, it also zeroed in on just how extraverted, neurotic, extraverted, conscientious, and open and agreeable people were. (Your personality, it was found, isn’t affected by birth order).
