Exotic probability is a branch of probability theory that deals with probabilities which are outside the normal range of . The most common author of papers on exotic probability theory is Saul Youssef. According to Youssef, the valid possible alternatives for probability values are the real numbers, the complex numbers and the quaternions.
Youssef also cites the work of Richard Feynman, P. A. M. Dirac, Stanley Gudder and S. K. Srinivasan as relevant to exotic probability theories.
Of the application of such theories to quantum mechanics, Bill Jefferys has said: "Such approaches are also not necessary and in my opinion they confuse more than they illuminate."
Famous quotes containing the words exotic and/or probability:
“Anthropology has always struggled with an intense, fascinated repulsion towards its subject.... [The anthropologist] submits himself to the exotic to confirm his own inner alienation as an urban intellectual.”
—Susan Sontag (b. 1933)
“The source of Pyrrhonism comes from failing to distinguish between a demonstration, a proof and a probability. A demonstration supposes that the contradictory idea is impossible; a proof of fact is where all the reasons lead to belief, without there being any pretext for doubt; a probability is where the reasons for belief are stronger than those for doubting.”
—Andrew Michael Ramsay (1686–1743)
