In this question, @user14111 refers to the book Lord of the Flies as being typically classified as science fiction. I remember reading it years ago, and having seen a movie adaption, but hadn't remembered any science fiction elements (apparently it is set during an offstage nuclear war.)
At any rate, it made me curious --is Lord of the Flies typically classified with SF? The references I looked up were ambiguous on the question, although the second one indicates there was an earlier draft with more of a SF orientation.
EDIT: To be clear, the question is not SHOULD this book be considered Science Fiction, but is there any reputable consensus one way or another about it? I had never personally considered it in that category, but user14111 had seemed to take it as a given that it is typically classified that way. As I said, the sources I consulted were ambiguous.
