According to the political scientist
Michael Barkun, conspiracy theories rely on the view that the universe is governed by design, and embody three principles: nothing happens by accident, nothing is as it seems, and everything is connected.
[6] Another common feature is that conspiracy theories evolve to incorporate whatever evidence exists against them, so that they become, as Barkun writes, a closed system that is
unfalsifiable, and therefore "a matter of faith rather than proof"
So, like I said, we better vet this guy...
