I think that Oceanic has hit on something. There really are multiple reasons for the popularity of conspiracy theories.conspiracy offers the ultimate sense of belonging. With conspiracy, you join an insider group that alone knows what is REALLY going on.
There's the need to impose order / feel in control instead of feeling helpless when something bad that doesn't seem to make sense happens to everyone (the classic evil gov't / corporations / rich people are doing something horrible to us helpless innocent victims).
There's the power of being an "insider", part of the group that REALLY knows what's going on.
And I also think that there's an entertainment aspect to it. Everyone loves a good, juicy story of the evil villains doing outrageous things to us, ESPECIALLY when it's presented as being true!
The "true" possibility helps to capture the imagination (consider the incredible popularity of the DaVinci Code book).
For example, years ago Kentucky Fried Chicken changed it's name to KFC. The rumour spread like wildfire that the name had to be changed because they were genetically modifying the chickens so much that they could no longer legally still be called chicken. Thus they had to change their name to KFC.
Great story! Evil corporations doing unspeakable genetic things to poor helpless chickens until they were no longer even chickens! And then they sell those genetic mutations to us to eat!
Except, of course, Kentucky Fried Chicken realized that advertising "Fried" in the world of healthier diets wasn't a great marketing plan, and that the Kentucky Fried Chicken name was way too long. So they wanted something short, memorable and that didn't contain the word Fried. And yes, they do advertise the word chicken, there were no genetic mutations of chicken into something else and there is no law that would have forced them to quit calling it chicken.
But facts NEVER stop a great story!
So I submit that we should add great (supposedly true!) story telling to the list of why conpiracy theories are so popular.
