Whose Prior Is It Anyway? A Note on "Rigorous Large-Scale Educational RCTs Are Often Uninformative"
Educational Researcher, v48 n6 p382-384 Aug-Sep 2019
A recent paper uses Bayes factors to argue a large minority of rigorous, large-scale education RCTs are "uninformative." The definition of "uninformative" depends on the authors' hypothesis choices for calculating Bayes factors. These arguably overadjust for effect size inflation and involve a fixed prior distribution, disregarding the trials' varied intentions.
