I see nothing in your lists of categories covering "bogus" knowledge, such as visions, intuition, hallucinations, faulty conclusions, jumping to conclusions, fallacious reasoning, prejudices, "common sense", revisionism, deceit by others, faulty memories, "recovered" memories, bias, preconceptions, indoctrination, propaganda, emotions, superstitions, rationalizations, bandwagon groupthink, etc. etc.

I always like to point out that it is our natural aversion to truth that causes the most trouble.
