Decker provides cogent response to Dombrowski et al ' s " all there is is g " bifactor intelligence research

 https://doi.org/10.1177%2F0734282920977718AbstractThe current article provides a response to concerns raised by Dombrowski, McGill, Canivez, Watkins,& Beaujean (2020) regarding the methodological confounds identified by Decker, Bridges, Luedke, and Eason (2020) for using a bifactor (BF) model and Schmid –Leiman (SL) procedure in previous studies supporting a general factor of intelligence (i.e., " g " ). While Dombrowski et al. (2020) raised important theoretical and practical issues, the theoretical justification for using a BF model and SL procedure to identify cognitive dimensions remain unaddressed, as well as significant concerns for using these statistical methods as the basis for informing the use of cognitive tests in clinical applications
