I could find an infinite number of examples like this, which completely disprove your assertion that confidence in the quality of something affects the quality of that thing.
You're saying that if you weren't terrified of flying, you wouldn't consider the quality of the experience better? That's crazy!
You seem to be assuming a totally objective measurement of quality applicable to something that has a subjective element. What I'm saying is that it doesn't matter to me if your contrived "quality" system says something it utter perfection if my perceived quality of that thing is zero. It's like telling a kid to eat his vegetables because they are good for him. We know they're good for him. He may even agree that they are good for him. But he hates the taste, and therefore won't eat them, even though by "objective" standards, he should be doing so.
