Yes, although I never thought about this before I bumped into this research, it is somewhat logical that the society will treat a bit differently someone called "Zmaj" (a Serbian name meaning "dragon") than someone called Predrag (a Serbian name meaning "very dear"). And if the society treats you a bit differently, you'll probably end up a bit different. : )

I love the way you managed to extend this matter to the potential genetics/history research, knowing these things (especially reaching the knowledge in this way) would be fascinating! 😊
