The panel was about skepticism and sci-fi, and one of the questions was, “Why do skeptics have such a bad reputation?” Why are they known as contentious, awful people?
John’s answer was essentially: Because they are unpleasant people. Paraphrasing: If debunking really Does It for you, then you’re probably a Stomper of Dreams.
As an unpleasant person, I have to kind of agree, but my answer went like this: There’s really no nice way to say, “Um, actually, that psychic isn’t really speaking to your dead relatives.” Saying it at all makes you the Dreamkiller, and that’s that. Either that, or you say nothing, in which case no one knows you’re a skeptic at all. Result: all skeptics are mean and unpleasant.
But I think there’s a third answer here: Popular entertainment has spent decades portraying skeptics as soulless or incomplete. Just check TV Tropes. Skeptics are Straw Vulcans — hyper-rational beings who are nonetheless incomplete and dead inside. Then they ‘come to their senses’ and become a Skeptic No Longer. Only when their character arc sees them learning to embrace at least a little unprovable bullshit do they become good and fully human. I think it’s a minor factor, but not an insignificant one.
