A **Bayesian** is someone who adheres to the Bayesian interpretation of probability, viewing probability as a level of certainty in a potential outcome or idea. This is in contrast to a frequentist who views probability as a representation of how frequently a particular outcome will occur over any number of trials.

The term **Bayesian** is also used to refer to an agent implementing precise Bayesian inference (see, for example, Aumann's agreement theorem).
