People joke about disliking people with certain names, but maybe that’s with good reason?
I’m fairly sure that if you have a large enough sample size of people from the same culture, you’ll be able to find trends in what kind of person people are based on their given names. Of course you’re not going to end up with the hardest of trends, but a “people named Boy are slightly more likely to commit crimes than average” wouldn’t be out of the realm of realistic conclusions.
Why would your name define what kind of person you are? There’s a lot of factors involved. Of course people may treat you slightly differently, and during your childhood years names can be more than enough reason for some good ol’ bullying. But much more influence probably comes from the parents.
You need to be a certain kind of person to name your son Boy, to use the same example. Different kinds of people will tend to have different kinds of preferences, and the names they give their children will reflect part of that. And of course, a parent is highly influential on a child’s personality.
So there you have it, the name-personality link.
