>> Nothing about "this study applies to this specific situation" is counter to Popper. However, if it fails to replicate in other situations, it tends to suggest at the very least "might be too specific to this situation to have practical application". Maybe not technically, but it does imply that "this specific situation" should be defined specifically, hence controls. I agree that broad applicability, and replicability are strong indicators of truth value. That said, there are pursuits of rational knowledge outside of Popperian ideals. That's not represented in the way Science, as an institutions works.
