Some time ago, when the anti-science, anti-evolution, religious literalist movie "Expelled" was making the rounds, it occurred to me that a strict 6-day, young-earth creationist idea of the world requires a particular confluence of perceptual filters in order to exist. There has to be an unquestioned acceptance of literalist religious dogma, a profound ignorance of some of the basic tenets of science, and a willingness to believe in a vast, orchestrated conspiracy on the part of all the world's geologists, biologists, archaeologists, geneticists, and anthropologists in order for this notion to seem reasonable.
I've been chewing on that thought for a while, and looking at the perceptive filters that have to be in place to accept any number of implausible ideas, from moon hoaxers to lizard people conspiracy theories to anti-vaccinationism.
And, since making charts is something I do, I plotted some of these ideas in a Venn diagram that shows an overlapping set of prerequisites for a number of different flavors of nuttiness.
