The way it has manifested most clearly in the situations I've encountered it is a basic difference in approach to writing and reading as concepts. They don't see writing or reading as a way to communicate, they see it as a puzzle they have to solve by following rules, so that they can return to communicating once the puzzle is out of the way. Unless they're in very casual/online settings, or very motivated to find specific information, they avoid the puzzle because it's annoying.
