To give a grand meaning to their small problems. Discuss. (Borrowed from a recent episode of Endgame.)
MSNBC: "I mean in a way Obamaâs standing above the country, above â above the world, heâs sort of God."
Actually, I think it was an insightful observation. You might feel the same if you allowed it to bounce around in that circus tent of yours.
The two, creation of conspiracy theories and creation of God, need not necessarily follow in complete lockstep. However, they may have a common seed. The one of a need for there to be grand and important answers to to comparatively trivial problems in the overall scheme of things. Religion, of course, goes beyond that. As Freud observed, religion will exist as long as there is wishful thinkiing and a fear of dying.
By the way, have you seen the movie "Flight From Death"? Based on Ernest Becker's work. iTunes has it. Also introduces terror management theory. This approach would likely make "conspiracism" a kind of mini [or pseudo]-immortality project. Dig a bit and you'd come back around to Freud, and the existentialists. : )
