Is there a word for success because of (as opposed to in spite of) ignorance / inexperience / unfamiliarity with the field in which you made your attempt, where a more experienced / knowledgeable person would have failed.
Will of course usually involve a degree of luck.
e.g. being ignorant of a field, you weren't aware of the difficulty of a task, and showed enough determination and actually succeeded, whereas someone who knew it better might have given up or reduced their efforts at a certain point knowing that it was too difficult to continue
Alternatively, you made a bad decision, which through a stroke of luck, turned out to be the one that worked (e.g. for Poker players - a bad Texas Hold'em player may call with a 2 & 7 and then win the hand because 2, 7, 7 appears on the flop)
(in light of some of the answers)
The phrase is not intended to be meant as complimentary (e.g. "the ability to think out side the box").
Also just wanted to emphasise that ignorance is a contributing factor to the success - i.e. someone more knowledgeable would have been likely to fail.
At first I was thinking a bit like "Pull a Homer" which is a fictional phrase defined in The Simpsons when Homer, through pure luck, presses the correct button to prevent a nuclear melt-down. But that's not quite correct because a knowledgeable person would have known the correct button to press.
