There is no agreement yet among the personality psychologists whether the General Factor of Personality (GFP) or the Big One, recently extracted from the inter- scale correlations of the Big Five and a number of other personality inventories at the apex of the personality hierarchy (Rushton, Irwing, 2008, 2010), is a substantive personality dimension or a mere research artifact. While the above mentioned key researches of the phenomenon state that GFP evolved as a result of natural selection for socially desirable behavior and there is evidence of the shared genetic dominance between the GFP, mental and physical health, and life history traits (Figueredo, 2010), others claim that it might be a result of a common response perspective on otherwise relatively independent traits (Riemann, Kandler, 2010).
