I do see what you mean, but if someone has no interest in a topic and they aren't studying an area then why would they seek them out?
I don't know much about art and art history. I can probably recall Lowry and a couple of artists from school, and Van Gough, or Monet because I sometimes go to galleries with DH, but there's countless other popular artists who I'd have nothing more than a recollection of, or have heard in passing. There's no doubt that some people would think as an educated professional surely I would know them, but why would I when it's not something I have an interest in?

You're quite right about numerous gaps. One thing I regularly tell trainees is the importance of reading up and reading around a subject.
I think the difference between my position and some on this thread is that I don't judge someone intelligence or look down on someone for not knowing something that I happen to know, nor do I have a list in my head of people/texts I think people should know.
If I asked my department to list the 10 texts they think every English teacher should have read, I'd get 10 different answers. Who am I, or anyone else for that matter, to decide that my 10 must have texts are better than someone else's?
