I would add the term "epistemological paranoia". Someone with a conspiracist view of the world views the question of 'how knowledge is produced' through a paranoid lens, and this ultimately determines all the logical fallacies that appear in conspiracist methodology.
I would also argue that, not only are conspiracists unable to construct scientific theory, they cannot even come up with an uncontaminated hypothesis, because any hypothesis they present will have a paranoid premise.
In my own field - countering Holocaust Denial - every statement I read from a denier has a conclusion that is predetermined by a paranoid premise. A paranoid hypothesis deliberately framed to avoid engagement with reasoned argument.
Conspiracy theory is thus anti-theory; anti-science; the essence of negationism.
