A Revised Sociogenomic Model of Personality Traits

Research output: Contribution to journalArticlepeer-review


In this article, I seek to update the sociogenomic model of personality traits (Roberts & Jackson, 2008). Specifically, I seek to outline a broader and more comprehensive theoretical perspective on personality traits than offered in the original version of the sociogenomic model of personality traits. First, I review the major points of our 2008 article. Second, I update our earlier model mostly with insights derived from a deeper reading of evolutionary theoretical systems, such as those found in life-history theory and ecological-evolutionary-developmental biology. In particular, this revision incorporates two evolutionary-informed systems, labeled pliable and elastic systems, that provide new insights into how personality traits develop. Third, I describe some of the implications of this new understanding of the biological and evolutionary architecture that underlies human phenotypes such as personality traits.
