Most people, even otherwise smart and successful people, don’t really know how to read. Words, for them, can interact with existing frames in their mind, but can’t create new structures. Most people also don’t really know how to listen to music, look at a beetle, or cook a meal. Much of the world exists as an apparition for all of us: we see it, but we can’t interact with it in a meaningful way because we don’t know enough about it. This seems obvious with coleopterology, not with reading, but I think it’s true. Just as doing sums doesn’t mean that one understands math, parsing sentences doesn’t mean that one understands how to read.
