A word for the phenomenon of "right result with wrong reasoning" [closed]

I call it dumb luck, and apparently so do a lot of other people. It seems to be a very popular title for all kinds of books.

According to Oxford Dictionary online, it means: "Pure chance", which logically can't have much if anything to do with reason.

  • The husband suspects that the wife has an affair. His evidences are wrong, but the wife is indeed having an affair. So finding out about it is sheer dumb luck. Or intuition.
