I recently had a series of unpleasant exchanges with some ET members in which I was accused of being a crank, and I thought the same of them (and still think so). But it got me wondering: have any other members here experienced something similar? It turns out there is a whole history of crankism in many fields. Offhand one would think an exact field of study like mathematics with its rigid definitions and rules of proof couldn't possibly be subjected to crankism, but one would be wrong in that assumption. Here's a book on cranks in mathematics: http://www.amazon.com/Mathematical-...=sr_1_2?s=books&ie=UTF8&qid=1322136563&sr=1-2 One wonders just how an individual goes off the rails to be a crank in exact fields like math and science, but it certainly makes the deep divisions in politics and religion more understandable. My focus in this thread is restricted to cranks in trading. Any other horror stories of dealing with cranks here or elsewhere as it relates to trading?
