How very bizarre. Bachmann's point seems entirely based on some view that we should only listen to authorities, and we should only listed to authorities that are correct all the time.
If your view of truth doesn't stem from "what I was taught", that is, from taking some Big Kahuna's word for it, then what Bachmann says seems nonsensical.
