Philip Pilkington writes: The financial economist Fischer Black – a mathematics PhD and founder of the popular Black-Scholes model of options-pricing that is much used today. In 1986 Black published a paper entitled simple “Noise” that is well-nigh unreadable. One gets the sense that “noise” for Black is a sort of ontological category that disturbs his sense of reality. “Noise” for Black is the equivalent to what “Sin” is to Christians. Everything bad in the otherwise harmonious world can be attributed to this ontological category “noise”. In this regard it is worth quoting from the abstract – which, it will be seen, is so poorly written as to be barely readable.

The effects of noise on the world, and on our view of the world, are profound… Noise in the form of expectations that need not follow rational rules causes inflation to be what it is… Most generally, noise makes it very difficult to test either practical or academic theories about the way that financial or economic markets work. We are forced to act largely in the dark.   Noise in Finance
