Feel free to test my hypothesis. Go up to random people in the mall, and start handing them pamphlets about how we're all being controlled by underground Reptilian aliens or that the sun is really a wormhole for aliens to use to stage an invasion against us, and try to engage them in a conversation about it. Take note of how they don't question the notion you just presented to them, politely take the pamphlet, and try to get away from you as fast as possible. This is them wanting to get away from the crazy person.
