In ordinary situations involving a small part of the universe, Born's rule
seems to work well for calculating probabilities of observations in quantum
theory. However, there are a number of reasons for believing that it is not
adequate for many cosmological purposes. Here a number of possible
generalizations of Born's rule are discussed, explaining why they are
consistent with the present statistical support for Born's rule in ordinary
situations but can help solve various cosmological problems.Comment: 8 pages, LaTe
