Study Finds Eldest Siblings Less Cooperative and Giving

Birth Order: Study Knocks First-Borns Off Their Pedestals

First-borns have a reputation for being just about perfect. They perform better on standardized tests and usually achieve a high degree of tangible success, being most likely to head the boardroom table.

But they're also known for their loyal and nurturing natures, which is why I am surprised a study found they are less cooperative, trusting, and reciprocating than their younger siblings. How can this be? My guess is when another child comes, they are forced to share their parents' attention and later their toys, friends, activities, and even rooms.

Researchers more or less agree with my theory, saying new siblings siphon off parents' attention, which creates more competition and less cooperation. If it was this simple, though, wouldn't children grow out of it? You'd think! Yet the study's sample was over 500 college students. I'd say it's because we still regress around siblings no matter how old we get, but, considering the study didn't use siblings, it seems it never stops!
