I don't have a source for you but I'm pretty sure I've read studies in the past that actually directly contradict what you're saying, studies where people were exposed to refutations of incorrect ideas, and later actually remembered the bad ideas but forgot that they were refuted. Which is to say, if you already know about the bad idea, having it refuted is presumably a good thing, but if you don't know about the bad idea in the first place, learning about it in order to have it refuted may actually backfire.
