Bayes' Theorem, Bayesian statistics and Bayesian inference have been the subject of sharp dispute in various writings about legal rules of evidence and proof. This article disentangles the many meanings of "Bayesianism." It sketches several competing interpretations of probability, some leading schools of statistical inference, and the elements of Bayesian decision theory. In the process, it notes the aspects of Bayesian theory that have been applied in studies of forensic proof.
