Bayesian Umps

I previously linked to discussion of a paper assessing the degree to which Bayes Theorem informs judicial decisions. To the extent that judges aspire to play an "umpire" role (and in a slight bow to opening day), I note Andrew Gelman's (Columbia--Statistics) recent post (here) discussing the argument (developed in this paper) that Bayes Theorem informs baseball umpires' decisions on whether to call a "ball" or "strike."
