Unified Conspiracy Theory
|Some dare call it|
The Unified Conspiracy Theory is a conspiracy theory, popular with some paranoids, that all of reality is controlled by a single evil entity that has it in for them. It can be a political entity, like "The Illuminati", or a metaphysical entity, like Satan, but this entity is responsible for the creation and management of everything bad.
Michael Barkun coined the term "superconspiracy" to refer the idea that the world is controlled by an interlocking hierarchy of conspiracies. Similarly, Michael Kelly, a neoconservative journalist, coined the term "fusion paranoia" in 1995 to refer to the blending of conspiracy theories of the left with those of the right into a unified conspiratorial worldview.
When facts appear to be threatening one's favorite conspiracy theory, creating a superconspiracy can be very useful as a way of dismissing them as 'part of the cover-up'.
This was played with in the Umberto Eco novel Foucault's Pendulum, in which the characters make up a conspiracy theory like this...except it turns out to be true.
