Abstract

Crupi and Tentori (2012) propose a condition of adequacy for any Bayesian measure of explanatory power, which they call Explanatory Justice. They criticize a measure recently defended by Schupbach and Sprenger(2011) for failing to satisfy this condition, and they offer a new explanatorily just measure of explanatory power. In this paper, we investigate Explanatory Justice’s merits as a condition of adequacy. We offer three arguments against this condition, thus supporitng the idea that a measure of explanatory power should rather be unjust. Then, in order to ensure that the debate advances beyond a mere battle of intuitions, we offer some new results derived from the empirical study described in (Schupbach, 2011a). All of this strengthens the case for Schupbach and Sprenger’s measure while simultaneously posing new challenges to Crupi and Tentori’s alternative proposal.
