3) “From Ontological Traits to Validity Challenges in Social Science: The Cases of Economic Experiments and Research Questionnaires”

Abstract

This article examines how problems of validity in empirical social research differ from those in natural science. Specifically, we focus on how some ontological peculiarities of the object of study in social science bear on validity requirements. We consider these issues in experimental validity as well as in test validity because, while both fields hold large intellectual traditions, research tests or questionnaires are less closely connected to natural science methodology than experiments.
