It's now been discovered that not only is the second-born sibling loved less (we all know the eldest child is the true favourite), they're also more likely to be troublemakers.
Second-born children were found to be bolder in school and more likely to be criminals. Yikes.
A new report from an MIT economist found that people born second in the family “are inclined to be more rebellious than their older siblings."
"In families with two or more children, second-born boys are on the order of 20 to 40 percent more likely to be disciplined in school and enter the criminal justice system compared to first-born boys even when we compare siblings."
It's thought to be from the 'role-model' effect
"The firstborn has role models, who are adults. And the second, later-born children have role models who are slightly irrational 2-year-olds, you know, their older siblings," the scientists told NPR.
So basically, it's their older brother's/sister's fault for being a bad influence... Or at least that's what this second-born tells herself.
