Abstract

No replication is truly direct, and I recommend moving away from the classification of replications as “direct” or “conceptual” to a framework in which we accept that treatment effects vary across conditions. Relatedly, we should stop labeling replications as successes or failures and instead use continuous measures to compare different studies, again using meta-analysis of raw data where possible.
