Non est Disputandum de Generalizability? A Glimpse into The External Validity Trial

Abstract: While empirical economics has made important strides over the past half century, there is a recent attack that threatens the foundations of the empirical approach in economics: external validity. Certain dogmatic arguments are not new, yet in some circles the generalizability question is beyond dispute, rendering empirical work as a passive enterprise based on frivolity. Such arguments serve to caution even the staunchest empirical advocates from even starting an empirical inquiry in a novel setting. In its simplest form, questions of external validity revolve around whether the results of the received study can be generalized to different people, situations, stimuli, and time periods. This study clarifies and places the external validity crisis into perspective by taking a unique glimpse into the grandest of trials: The External Validity Trial. A key outcome of the proceedings is an Author Onus Probandi, which outlines four key areas that every study should report to address external validity. Such an evaluative approach properly rewards empirical advances and justly recognizes inherent empirical limitations.
