It's interesting because only children and oldest children score highest on intelligence tests and tend to have a reputation for being the highest achievers. And you can kind of understand that with oldest children. They need to play a parental role within their family and they often reflect their parents. Whereas youngest children are often real radicals who get to live on their own terms a little bit more. Only children are fascinating. Because only children tend to be a little bit more of a wild card. You can stick with your parents model. Or you can take all of that intelligence and verbal ability and go in a totally different direction with it based on other factors of your personality or upbringing. So you could be conservative. Or you could also be really radical. And I find the potential in that range plus the higher achievement that only children tend to have to be an exciting thing.
