On the Fediverse fellow fedizen GPIO27 provided a good observation:
There are some societies called “high context” societies; usually rural, close-knit groups where everyone knows everyone, and everyone also knows everyone else’s business. There is no privacy. You can’t really keep a secret. And people in such societies are very, very cautious, very jealous of their reputation, very careful in their interactions, for this reason. Also very non-trusting of outsiders.
“Low context” societies are more anonymous, like big cities with large numbers of people. You can be private, you can be anonymous, you can go about your business with nobody knowing what you are up to or even know who you are. People in such societies tend to be more brash, direcvt, confrontational (“I’m walkin here!”) and more welcoming of outsiders, since everyone is more or less an outsider.
With social media, everyone knows each other’s business, there’s no privacy, and people are indeed behaving more like a high-context society-- all across the world.
