Definition of Conspiracy theorist

Conspiracy Theory is a 1997 thriller directed by Richard Donner. It stars Mel Gibson as Jerry Fletcher, an eccentric taxi driver who believes that many world events are actually government conspiracies.

A conspiracy theory usually attributes the ultimate cause of an event or chain of events (usually political, social, pop cultural or historical events), or the concealment of such causes from public knowledge, to a secret, and often deceptive plot by a covert alliance of powerful or influential people or organizations. Many conspiracy theories imply that major events in history have been dominated by conspirators who manipulate political happenings from behind the scenes.
