i'm very familiar with Mick West. His debate with Eric Weinstein is probably one of the most informative examples of conspiracy miasma. (eric and his brother might actually be the miasma kings)

My thought is that it requires someone *wanting* to see the truth and be genuinely skeptical of their own beliefs. Unfortunately the mindset that turns people into conspiracy theorists (namely a concerted effort to avoid cognitive dissonance) is the same that keeps them there.
