We're days away from the 10-year anniversary of 9/11. Slate has an excellent piece on the "Truthers" and how they are impervious to reason. Here's a quote from Philip Zelikow (the 9/11 Commission's executive director), who makes this observation about the 9/11 conspiracists:
"I play a very prominent part in their demonology of the world, but the people themselves don't come across like raving lunatics," Zelikow says. "They're often people who in many respects seem quite sincere, very concerned, very patient. They just are fixated." The obsessive nature of conspiracism makes it very difficult to discuss or debate issues with some of the more hardcore believers. "They're not really able to listen to you," Zelikow says. "It's almost like you'll say something and then the tape will just replay its loop again."
