Title: Why internal validity is not prior to external validity: Paper presented at PSA 2012
Abstract: In Persson & Wallin (2012) 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. This note is an invited summary of these results.
