When you’re the last-born child of the family, you have to contend with being the smallest and weakest of the bunch.
“That makes them more inclined to be rebellious (the better to overturn the system),” Kluger wrote. “It also makes them funnier, more intuitive and more charismatic than their older siblings. If you can’t use strength and size to prevent yourself from getting pushed around, you learn to disarm with charm and to pay attention to other people’s thoughts and motivations in order to stay one step ahead of them.”
Younger siblings are more likely to participate in high-risk sports than their older siblings, according to researchers from the University of California, Berkeley and Guildford College. This translates to bigger risk-taking in the professional world, according to Kluger: “Last-borns are more likely to blow up the tracks and buy new trains — reinventing a company entirely, rather than simply reforming or improving it.”
Another study found that last-borns are more relaxed, easy-going, and funnier.
“Multiple studies have shown that the baby of the family is likelier than other siblings to be a writer or artist or especially a comedian — Stephen Colbert, the youngest of 11 siblings, is a great example of this,” Kluger wrote. “All this, again, speaks to the last-born’s ability to get inside other people’s heads. You can’t write a powerful poem if you don’t deeply understand what moves your potential readers.”
