From my limited experience (being a child and raising one child) I would say that the problem is more that we (as adults) pretend that the simplified thing is the whole picture.

Every time someone told me: "this is a simplified version to give you a basic understanding and later you will be able to learn more accurate versions" that was tremendously helpful and sometimes it sparked my curiosity and motivated me to look stuff up myself.

I mean we should get ahead of the realisation that it doesn't add up.
