It's actually a reasonable epistemological tactic: in a world where there are more issues you need to be clear on than you can possibly inform yourself about, you need some shortcuts. One shortcut - a shortcut that's failing - is to say, "Well, I'll provisionally believe whatever the expert system tells me is true." Another shortcut is, "I will provisionally disbelieve in whatever the people I know to act in bad faith are saying is true." That is, "schismogenesis."
