Last year , a friend posted to his blog a brief excerpt of an NPR radio show which pitted a Special Relativity challenger against one of its supporters. During the introduction, the reporter mentioned a test developed by a UC Riverside mathematician. This test, The Crackpot Index , is a combination of satire and seriousness. In reality, it highlights a number of common pitfalls that are repeatedly made by those challenging the establishment. If you score too high on this test, you will be labeled a Crackpot.
