Sometimes, when confronted with woo, it is hard to know exactly what sort of woo you're dealing with. To simplify this challenge while sparing you the agony of enduring any more explanations of ear-candling or aromatherapy than is strictly necessary, Crispian Jago has compiled a handy Venn Diagram of Irrational Nonsense.

The curiously revered world of irrational nonsense has seeped into almost every aspect of modern society and is both complex and multifarious. Therefore rather than attempt a comprehensive taxonomy, I have opted instead for a gross oversimplification and a rather pretty Venn Diagram.

In my gross over simplification the vast majority of the multitude of evidenced-free beliefs at large in the world can be crudely classified into four basic sets or bollocks. Namely, Religion, Quackery, Pseudoscience and the Paranormal.

However as such nonsensical beliefs continue to evolve they become more and more fanciful and eventually creep across the bollock borders. Although all the items depicted on the diagram are completely bereft of any form of scientific credibility, those that successfully intersect the sets achieve new heights of implausibility and ridiculousness. And there is one belief so completely ludicrous it successfully flirts with all forms of bollocks.

Religious Bollocks ∩ Quackery Bollocks ∩ Pseudoscientific Bollocks ∩ Paranormal Bollocks = Scientology
