I’ve left out some borderline items from the survey, including “The medical industry and the pharmaceutical industry ‘invent’ new diseases to make money.” (At one level, that’s obviously true about pharmaceutical companies; the question is whether the new diagnostic entities correspond to genuine deficits.) And of course the “lizard people” question depends on what phylum you think Dick Cheney belongs to. But the outlier in the above sample lies so far out that I’m frankly puzzled. Not every statement about organized wrongdoing is a “conspiracy theory” in the pejorative sense of that term.
