I think a large portion of the conspiracy theorist population probably has a mental illness that makes them susceptible to delusional thinking. Delusional people can lead very normal fully functioning lives, but mix a certain topic that offers patterns which make their brain go down a certain path, and they suddenly become very adamant about believing something that is illogical and irrational. There is probably litt…
I don't think being a "conspiracy theorist" is delusonal at all if there are overwhelming facts supportig the theory. When did it become crazy to "...have an explanatory proposition that accuses two or more persons, a group, or an organization of having caused or covered up, through secret planning and deliberate action, an illegal or harmful event or situation." Watergate, Iran-contra, prism, the cia drug traffickin…
The vast majority of "conspiracies" are more like Underpants Gnomes business models. There's no explantory proposition anywhere. There's no overwhelming theory - put ten truthers in a room and you'll get ten wildly different theories (if you get a theory at all), and no overwhelming facts.
Watergate didn't require any theory - people connected with the Nixon administration were caught red-handed breaking and entering. It's obvious why they might do what they did and to ask who knew what/when. It was obvious people had a motive for covering up a criminal action. It was just a matter of documenting it.
When Iran leaked the Iran-hostage story via a Lebanese newspaper, nobody had a conspiracy theory before that. There was no "why would Reagan do that?" - the motivation was obvious and it was in print. When the -Contra side came out, no one had a conspiracy theory about a connection there. It was more investigation/leaks and a total surprise.
So I don't see where Conspiracy Theories really equate to uncovering Criminal Conspiracies. They seem to be more exclusive than related to each other.
