How long do you think it would take, as an American, to figure out of someone is from New York, Boston, or Alabama? You'd know practically the moment they opened their mouth.
Yeah, it might take you longer to figure out if someone was from Florida or California, but that would probably come out relatively quickly in how they talk about beaches.
Humans group and identify others (often wrongly) really quickly.
I don’t think this is a great comparison. Since I’m American, I’m going to pick something else that would be a bit more foreign: I can “tell” if a person is Scottish or Irish from their accent, but I have absolutely no idea how to know if someone is of a certain caste. I could meet up with a carbon copy of myself and not be able to discern their caste because I have zero knowledge of why I “look like” the one I belong to.
