I think that's called culture, but last time I said that someone told me to be careful saying that or I'll get killed for implying there's a such thing as national character. I don't even know why I would get killed for that because that's still not racist (I mean, if you're around a bunch of people who act a certain way and promote acting a certain way, aren't you likely to pick it up? so statistically culture should relate to personality, even if there are exceptions too) but the word "national" is now always followed by "socialist" or something.
