Self-esteem and higher-order factors of personality: A reply to Simsek

Simsek (2012) argued that earlier research by Erdle and colleagues on the relationship between self-esteem and higher-order factors of personality used “poor statistical methodology”, that “their results may be untenable”, and that the results of his “high-level data analysis” are “the first to show the importance of self-esteem in the differentiation between stability and plasticity”. In this rejoinder, it is argued that the statistical methodology used by Erdle and colleagues demonstrated the effect of controlling self-esteem on the relationship between stability and plasticity earlier and more accurately than that used by Simsek (2012). Moreover, it is argued that self-esteem might not be a biasing factor, but instead might be a theoretically expected substantive correlate of the Big Five and of higher-order factors of personality. Finally, it is argued that a hierarchical structure of personality, with a general factor of personality (GFP) at the apex, might have a neurological basis in the activity of the prefrontal cortices.
