NCA discussed at QCA expert meeting

Several experts who have published on necessary conditions have attended the 4th International QCA expert meeting in Zurich, Switserland, 7-8 December 2016 to discuss the development of QCA. Gary Goertz argued that cases without the outcome and without the condition can be used for studying necessary causal mechanisms, Barbara Vis (photo) discussed how qualitative data can be transfered into set membership scores, Patrick Mello presented his views on improving robustness of QCA findings, and Jan Dul explained why NCA identifies more necessary conditions than  QCA, and presented the "calibration evaluation tool" that showed the (large) effects of QCA's calibration of original data on QCA's necessity consistency and NCA's necessity effect size. Peer Fiss, one of the leading QCA researchers in management, expressed his appreciation for the growth of NCA and for the calibration evaluation tool. The differences between NCA's and QCA's necessity analysis are discussed on this page.
