Thank you for identifying a 3rd way to produce conspiricism:
I'd thought there were only 2 ways, but am now corrected!
https://www.amazon.ca/Tribal-Leadership-Leveraging-Thriving-Organization-ebook/dp/B0012GTZFC/ identifies that people subject to narcissist-culture, pushed into mode-2 "MY life Sucks." mode, become conspiricist. ( the book is on the 5 cultural-modes, & how to cause oneself to be in the healthiest 4 & 5 modes )
https://www.amazon.ca/Nutrient-Power-Heal-Biochemistry-Brain-ebook/dp/B00J75IQUA/ identifies that people with a biochemistry-distortion of being undermethylated-DNA can be conspiricists, or delusional, or autistic, or "schizophrenic", or depressed... Conspiricism is a real risk for undermethylated, though. I'm undermethylated, & have replicated his successful-treatment 4 times, how ( takes a few months to work, on me )
educated-incompetence ( engineered to be incompetent "education", to protect ignorance against the threat of intelligence ) can also be a cause.
John Taylor Gatto pointed-out that the American education-system was modelled on low-caste education of India, and paid-for by the coal industry to prevent people from becoming like Lincoln or Ben Franklin, anymore, in one of his books...
