Narcissism and conspiracy beliefs

Summer reading. Something to ponder on.
Maybe one get some answers if and when one dives into the text. But a few thoughts only, based on the title and abstract. States and traits? Boosted narcissism as something you are, basically. Or more like something that a certain system of thought might tempt you to. Because conspiracy theories, even the most far-reaching -Trump as a Savior, chemtrails, etc. – I mean, there are lots of people who are attracted to such world declarations. Sure, there’s something “narcissistic” about it. Us and them. The darkness, the threat, the stupidity, are on the outside of ourselves, etc. But on deeper level is it real Narcissism?
