Based on the OCEAN model, there are different scientific analyses and studies that show the relevance and impact of its factors and facets on work performance:

• Consciousness and Agreeableness are relevant to success in many jobs, from low to high levels of job complexity.. Sackett, P.R. and P.T. Walmsley (2014), “Which personality attributes are most important in the workplace?“, Perspectives on Psychological Science, Vol. 9(5), pp. 538-551, http://doi.org/10.1177/1745691614543972
• The “Competence” (or self-efficacy) facet, within the Consciousness factor, and work performance correlate significantly.  “Stajkovic, A.D. and F. Luthans (1998), “Self-efficacy and work-related performance: A meta-analysis“, Psychological Bulletin, Vol. 124(2), pp. 240-261, http://doi.org/10.1037/0033-2909.124.2.240
• Overall job performance is difficult to predict, however, the facets of the different OCEAN factors allow for predicting specific areas. Judge, T.A. et al. (2013), “Hierarchical representations of the five-factor model of personality in predicting job performance: Integrating three organizing frameworks with two theoretical perspectives”, Journal of Applied Psychology, Vol. 98(6), pp. 875-925.
• Not only in the work performance, the personality also influences the educational evolution and the vital development and for that reason, the OECD is going to carry out international macro studies to know data and to establish possible actions.  Kankaraš, M. (2017), “Personality matters: Relevance and assessment of personality characteristics”, OECD Education Working Papers, No. 157, OECD Publishing, Paris, http://dx.doi.org/10.1787/8a294376-en
• Personality can predict health (especially mental health) and well-being. The most influential factors are Kindness, Responsibility and Neuroticism (emotional range). Strickhouser, J.E, E. Zell and Z. Krizan (2017), “Does personality predict health and well-being? A metasynthesis”, Health Psychology, Vol. 36(8), pp. 797-810, http://doi.org/10.1037/hea0000475

If to learn more about the impact of personality (among other factors) in our lives the “papers” are not your thing, we recommend you to deepen in the findings of the longitudinal study Dunedin.

“In 1972, the Dunedin School of Medicine in New Zealand decided to study the children born in the city in that year and follow them throughout their lives. The results of the Dunedin Study are today the greatest source of information to determine what makes us who we are”
