Legal theorists sometimes speak of "the" Bayesian interpretation of evidence, inference, proof, and probability. However, see Sharon Bertsch McGrayne, The Theory That Would Not Die 129 (Yale 2011):
Bayesian theories mushroomed in glorious profusion during the 1960s, and Jack Good claimed he counted "at least 46656 different interpretations," far more than the world had statisticians.1 [1. I.J. Good, "46656 Varieties of Bayesianism," Letter to the Editor, 25 American Statistician 62-63 (1971).] Version included subjective, personalist, objective, empirical Bayes (EB for short), semi-EB, semi-Bayes, epistemic, intuitionist, logical, fuzzy, hierarchical, pseudo, quasi, compound, parametric, nonparametric, hyperparametric, and non-hyperparametric Bayes. ... When asked how to differentiate one Bayesian from another, a biostatistician cracked, "Ye shall know them by their posteriors."
