Why internal validity is not prior to external validity

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


We show that the common claim that internal validity should be understood as prior to external validity has, at least, three epistemologically problematic aspects: experimental artefacts, the implications of causal relations, and how the mechanism is
measured. Each aspect demonstrates how important external validity is for the internal validity of the experimental result.
