I've Found It, but What Does It Mean? On the Importance of Theory in Identifying Dominant General Factors

Extract
In their focal article, Ree, Carretta, and Teachout (2015) based their definition of a dominant general factor (DGF) on two criteria: (a) A DGF should be the largest source of reliable variance; (b) it is influencing every variable measuring the construct. Although detailed attention has been paid to the statistical properties of a DGF, I believe another criterion of equal if not greater importance is the theoretical justification to expect a DGF in the measurement of a construct. In the following commentary, I will highlight the importance of theory as another important criterion when determining the meaningfulness and usefulness of DGFs, discuss the risks of creating a DGF without any theoretical guidance, and elaborate on the complexities surrounding job performance as a detailed example to illustrate why theory is important before extracting a DGF from performance ratings.
