Replication is a study for which any outcome would be considered diagnostic evidence about a claim from prior research. What had been perceived as replications were not anymore because new evidence demonstrated that they were not studying the same thing. The generalizability space is large because of theoretical immaturity; there are many conditions in which the claim might be supported, but failures would not discredit the original claim. Because replication is defined based on theoretical expectations, not everyone will agree that one study is a replication of another.

The technical storage or access that is used exclusively for statistical purposes. The first experiment uses repeats. This produces, in a sense, one data point. Using the same procedures is an interim solution for not having clear theoretical specification of what is needed to produce evidence about a claim. You can create a design with both repeats and replicates, which enables you to examine multiple sources of variability. Prior commentators have drawn distinctions between types of replication such as direct versus conceptual replication and argue in favor of valuing one over the other (e.g., [9, 10]).
