Personality and Life Expectancy (Conscientiousness and Non-Cognitive Skills)

Following on from growing evidence that higher levels of conscientiousness are associated with greater health protection, Kern and Friedman (2008) show that conscientious individuals tend to live longer. Associations with longevity were strongest for the achievement (persistent, industrious) and order (organised, disciplined) facets of conscientiousness.

This suggests that there may be links between longevity and what economists refer to as non-cognitive skills. Even more interesting is the approach taken to de-compose (overall) conscientiousness into a range of non-cognitive skills, including persistence, industriousness, organisation and discipline.

The importance of concientiousness is also documented by Terracciano et al (2008). Furthermore, this study shows that the association of personality traits with longevity is largely independent from the influence of smoking and obesity; longevity was associated with being conscientious, emotionally stable, and active (a facet of extraversion).

Low levels of neuroticism and high levels of extraversion are also associated with a lower later-life risk of developing dementia, according to recent research in Neurology (reported in the Leitrim Observer).
