Analyzing relationships of necessity not just in kind but also in degree: Complementing fsQCA with NCA

Collaborators: Barbara Vis and  Jan Dul

Analyzing relationships of necessity is important for both scholarly and applied research questions in the social sciences. An often-used technique for identifying such relationships—fuzzy set Qualitative Comparative Analysis (fsQCA)—has limited ability to make the most out of the data used. The set-theoretical technique fsQCA makes statements in kind (e.g., ‘‘a condition or configuration is necessary or not for an outcome’’), thereby ignoring the variation in degree. We propose to apply a recently developed technique for identifying relationships of necessity that can make both statements in kind and in degree, thus making full use of variation in the data: Necessary Condition Analysis (NCA).With its ability to also make statements in degree (‘‘a specific level of a condition is necessary or not for a specific level of the outcome’’), NCA can complement the in kind analysis of necessity with fsQCA.
