Abstract: We develop a framework for accumulating evidence across studies and apply it to understand the theoretical foundations of replication. We focus on two ways of assessing empirical results across studies: target-equivalence, where empirical targets across studies are the same, and target-congruence, where empirical targets’ sign is the same across studies. Our results show how each of these assessment criteria are related to distinct formulations of external validity. We stress the importance of holding aspects of a research design fixed across settings when accumulating evidence across studies, which ensures that questions of external validity can be addressed using replication.
