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:
“I did not know the woman I would be
nor that blood would bloom in me
each month like an exotic flower,
nor that children,
two monuments,
would break from between my legs....”
—Anne Sexton (1928–1974)
“Only in Britain could it be thought a defect to be “too clever by half.” The probability is that too many people are too stupid by three-quarters.”
—John Major (b. 1943)
