Possibilities for Probabilities and
Reasoning about Boltzmann Brains


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 Borns rule are discussed, explaining why they are consistent
with the present statistical support for Borns rule in ordinary situations but can help solve various cosmological problems. One application is to Boltzmann brains, which can be kept at bay by
Bayesian reasoning.
