From what I understand, this is a burgeoning area of serious academic study. A lot of it seems aimed at psychoanalyzing conspiracy theorists. There are people who are arguing some good points though too.

A sign greets the scholars on the opening evening."I get the feeling that a lot of philosophers can poke a hole in anything," Ted Goertzel complained, his voice radiating prickly impatience. The site was the University of Miami, where nearly 50 scholars from institutions across Europe and America had gathered to discuss conspiracy theories in a room named for Dwayne "The Rock" Johnson. Goertzel, a retired Rutgers sociologist, was addressing a panel of philosophers who had indeed just spent an hour poking holes in popular notions about conspiratorial beliefs. One had presented a paper with the cheeky title "Why Do We Believe Conspiracy Theories Exist?"
Goertzel wasn't buying it. "I think the reason we think conspiracy theories exist is because they exist," he declared.
It was neither the first nor the last contentious moment of the conference, which took place on the university's Coral Gables campus from March 12 to 14. The event had been organized by Joseph Uscinski and Joseph Parent, a pair of political scientists who did a commendable job of looking past their own field to invite people from different disciplines. And when I say "different disciplines," I don't merely mean "people who study different things." I mean "people with entirely different tool kits for understanding the universe."
The result was a friendly but frequently combative gathering of tribes, each of which had to suss out the other gangs' languages and worldviews. Here's a rundown of the rival clans:
The social psychologists. For this group, the study of conspiracy theories is mostly a matter of conducting experiments. The psychologists have developed several questionnaires that are supposed to show how prone a subject is to different sorts of thinking, including conspiracism. In a typical study, volunteers might answer those questions, read an article (or be "exposed to" the article, as the experimenters like to put it), and then give their responses to the story. Then the researchers start looking for correlations.
