The Benefit of a Chunk

I wonder if an unearned generalization has the character of like, okay, if a chunk, you know, these matrioshka dolls. What's a good analogy for this? What would be a better analogy? I don't know. But I wonder if someone else says a generalization or tries to give you a chunk and you have it dealt with the connections, I wonder if it's just a matrioshki doll with nothing inside of it.
