I think one reason may be that people are used to the "completeness" of physics; it's the science that people seem historically most ready to declare "done", and it does explain a lot very well. This may make it particularly unsettling to learn about this vast frontier of ignorance.

Really? Who are these people that consider physics to be complete? I'm kind of skeptical that there's a large body of folks that know enough about physics to even ponder its completeness, but who also are unaware of the discrepancies between general relativity and quantum mechanics.
