Sometimes I wonder if part of it has to do with the way thoughts are organized. Think about politics in general, and you can be fine; but think about Timecube, or the apollo missions, or whatever else, suddenly you see a large conspiracy.
The biggest thing that made me think this, actually, was talking with someone who felt that global warming was a huge conspiracy by the government, started from the '50s (in "The Unchained Goddess", which I linked) on up all the way to today, and planted so that the government gets more power from the corps. Yet he was also 100% supportive on the War on Iraq, Afghanistan, etc., calling himself "pro-War". The same body he felt responsible for a conspiracy to control people, he trusted to use the military. It's like he has one "thought group" that involves the "War on Iraq", and another "thought group" that involves "Global Warming", and the two shall never meet.
