Crispian Jago, the UK-based skeptical blogger at The Reason Stick and co-founder of the Hampshire Skeptics Society and Winchester Skeptics in the Pub, has just published a fantastic Venn Diagram of Irrational Nonsense. Yes, he says it is a "gross over simplification," but I have to love how the perfect intersection of religion, medical quackery, the paranormal and of pseudoscience appears to be nothing other than Scientiology.
Be sure to check out Jago's other projects, like the Skeptic Trumps cards (a few years ago, he did one for Randi and one for me, among many other folks), and fun resources like his Modern Science Map, his Handy Alternative Therapy Flowchart and his Periodic Table of Irrational Nonsense. The man sure knows how to communicate important information with smart graphic design.
