The HEXACO personality model does not provide an accurate organization of the personality domain: it over-relies on lexical research, focuses on one level of the personality hierarchy, and lacks coherent theory. The HEXACO personality inventory overemphasizes internal consistency, factorial homogeneity, and unidimensionality; lacks construct coverage and has construct validity problems.
