Conspiracy Theorists vs Conspiracists
Let me add to the topic by providing this from David Runciman in his review for The London Review of Books [January 9th, 2014, Page 31] of Alex Ferguson's My Autobiography:
"Alex Ferguson is a conspiracist, which is not the same as being a conspiracy theorist. Conspiracists see patterns of collusion and deceit behind everyday events. Their default position is that someone somewhere is invariably planning something. Conspiracy theorists go further: they want to join up the dots and discover the overarching pattern that makes sense of seemingly unrelated happenings. They are looking for the single explanation that underwrites everything. A conspiracist thinks that nothing is entirely innocent. A conspiracy theorist thinks that nothing is entirely incidental. Conspriracists can be devious, suspicious, confrontational and difficult to be around but they are also capable of making their way in the world, leveraging their paranoia into real power. Conspiracy theorists are often simply nuts."
