Kevin Standlee: Fandom Is My Way of Life

To put it in technocratic terms (that being all you appear to understand): if the electorate has no confidence in the system, one of terms in your utility equation is zero.

Unless you don't think that voter confidence in the system has any relevance, which is a patently absurd on its face.

Every time I fly, I feel a lack of confidence in the planes. Call it paranoia, because I know better, but I just feel scared someone will have done something wrong, and I'm going to die. Yet the planes still deliver me safely each time.

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.
