Whose prior is it anyway? a note on 'rigorous large-scale educational RCTs are often uninformative'.

Abstract

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 over-adjust for effect size inflation and involve a fixed prior distribution, disregarding the trials’ varied intentions.
