An example of anti-epistemology run riot would be New
Ageism - "faith" was originally developed by scriptural religions, but with sacred texts and standard teachings to put boundaries around what you were allowed to have faith in. New Ageism kept the notion that unjustified belief was a noble thing, but dropped the scriptures, with the result that they now have faith in unicorns, UFOs, homeopathy, pyramid power... The term anti-epistemology refers to bad explicit beliefs about rules of reasoning, usually developed in the course of protecting an existing false belief - false beliefs are opposed not only by true beliefs (that must then be obscured in turn) but also by good rules of systematic reasoning (which must then be denied).
Anti-epistemology was formerly known as Dark Side Epistemology but this seems to have been an overly poetic term that led to confusion -
it refers to bad explicit epistemology, not to the defense of bad particular beliefs.
dark side epistemology refers to a set of techniques developed to argue for a confusion or a lie. A victim of dark side epistemology not only learns to protect the targeted false beliefs, but also
systematically acquire new false beliefs, further departing from reality.
