Actually, the term "Dark Side Epistemology" seems to be tending towards over-generalization (being used to describe any persuasive art, say, rather than explicitly defended systematized bad rules of reasoning). "Dark Arts" isn't even a term of my own invention; someone else imported that from Harry Potter. It seems to be trending towards synonymy with "Dark Side". I may have to deprecate both terms as overly poetic and come up with something else - I'm thinking of Anti-Epistemology for systematically bad epistemology.
