How crazy. I always wondered if there is a connection between the given name and how others treat this person. A "Hans" is different in character than a "Benjamin" and "Isolde" is different to "Hannah". That this has such an effect that you can see the results in their face is astounding.
Based on this it may even be possible to see it in the epigenetic part of their DNS. Just imagine, we could find out how ancient people were named. Or the real name of Özi, the frozen mountain mummy...
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! 😊
