Any principle offered to underwrite the imposition of alpha-adjustment procedures must be applied consistently. Hewes (2003) and Tutzauer (2003) propose that alpha adjustment can appropriately be mandated when the set of tests concerns the key claims of a single theory. But consistent application of this reasoning though, commits one to bizarre beliefs and research practices—which suggests that this reasoning does not provide a satisfactory rationale for imposing alpha adjustments.
