For research to have high conceptual external validity, it must indeed investigate a broad range of policy variables and ensure that the dependent variables have practical utility. This ensures that the findings can be generalized across different settings and populations. Structural external validity does not guarantee functional and conceptual external validity, as these aspects of external validity address different concerns. Similarly, the similarity in results between field and lab studies does not guarantee that the same psychological processes were at play, as different factors could produce similar outcomes in different settings.
