Amongst the Persuaded(2004)

The human susceptibility to delusional thinking has, at least, this defining characteristic: easy to spot in others, hard to see in oneself. The filmmaker, racked by the inescapable observation that it is delusional thinking that is the common denominator driver of so many contemporary man-made disasters gins up a vehicle meant to ruthlessly uncover and expose his own particular brand of pathological believing. This film is about us. I believe its true. See the iron jaws of the mechanism at work as the filmmaker falls into the biggest and most obvious delusion of all: the belief that he can master his own delusions by making a film about them.
