Fun stuff in there. But this is wrong-
The world he was originally created for was one obsessed with science. The Victorian era saw the birth of Charles Babbage's own "calculating machine", a forerunner of modern computers. Many early fictional detectives – Edgar Allan Poe's Dupin, Jacques Futrelle's "Thinking Machine" – were characters who prided themselves on their systematic, unemotional approach to solving mysteries.Mania involves all kinds of cognitive biases. Especially the one where you believe you are thinking especially clearly. The illusion of competence. Heh.
Holmes, too, boasts of his lack of emotions – "I am a brain, Watson. The rest of me is a mere appendix" – and his ability to separate fact from theory. "I make a point of never having any prejudices," he tells Inspector Forrester in The Adventure of the Reigate Squires, "and of following docilely wherever fact may lead me." Like Babbage's Difference Engine, there is no personality involved, only the application of a method. "He was," says Watson, "the most perfect reasoning and observing machine that the world has seen."
