Key Factors:
- Among the many “Big Five” personality traits, conscientiousness is particularly predictive of dwelling an extended life.
- The persona trait has additionally been linked to health-related behaviors resembling smoking and sleep, which can assist clarify its relation to longevity.
- Latest analysis suggests conscientiousness can be associated to immune system perform.
One cause scientists and laypersons alike are interested by persona is that the idea is so intuitive. It corresponds to our fundamental remark that particular person conduct is organized into patterns and that these patterns differ between people.
Science, for its half, is interested by description, and persona fashions describe individuals—and the variations between them—in helpful methods. A preferred and well-studied mannequin is the Big Five, which measures 5 fundamental and comparatively secure traits: Neuroticism, Openness, Agreeableness, Extraversion, and Conscientiousness. Particular person variations in ranges of those traits are assumed to account for noticed variations in patterns of conduct.
But science and laypeople alike are additionally interested by prediction, in utilizing one variable to forecast one other, in peering into the longer term. Character, it seems, will help us do this as effectively. Huge 5 persona trait measures are predictive of assorted points of individuals’s lives, from Internet usage to academic achievement to marital satisfaction.
One final result area attracting a lot attention amongst persona researchers is longevity. Over the previous 30 years, proof has accrued to recommend that points of persona certainly predict longevity, and that personality-related differences on this final result are comparable in measurement to these linked to socioeconomic standing and intelligence.

For instance, the psychologists Stephen Soldz and George Vaillant of Harvard Medical Faculty (1999) examined information from 163 males adopted prospectively for over 45 years. They discovered that “Conscientiousness in school was the very best predictor of what occurred to the boys sooner or later, whereas Neuroticism in late midlife was the very best correlate of life course functioning throughout a wide range of domains.”
Howard Friedman and colleagues on the College of California, Riverside (2010) studied a pattern of 1,312 individuals who have been assessed for persona as younger adults in 1940. The researchers then assessed individuals’ wholesome growing older in 1986, and picked up their loss of life certificates by means of 2007 to measure longevity. Evaluation of those information confirmed that “neuroticism predicted worse bodily well being and subjective well-being in outdated age and, for girls, greater mortality danger, however for males, neuroticism predicted decreased mortality danger. For each sexes, extraversion predicted old-age social competence, whereas conscientiousness predicted males’s old-age productivity.”
Reviewing (2011) the hyperlinks between persona traits and longevity, Benjamin Chapman of the College of Rochester and colleagues concluded, “there may be good proof that greater stage of conscientiousness and decrease ranges of hostility and Kind D or ‘distressed’ persona are related to better longevity. Restricted proof means that extraversion, openness, perceived management, and low ranges of emotional suppression could also be related to longer lifespan. Findings relating to neuroticism are combined, supporting the notion that many part(s) of neuroticism detract from life expectancy, however some parts at some ranges could also be wholesome or protecting. Total, proof suggests numerous persona traits are important predictors of longevity.”
Jason Strickhouser and colleagues (2017) carried out a ‘metasynthesis’ (evaluation of a number of meta-analyses) to look at relations between persona traits and well being variables in over 500,000 individuals. They found that “when entered concurrently, the Huge 5 traits have been reasonably related to general well being … results have been bigger amongst agreeableness, conscientiousness, and neuroticism than extraversion or openness to experience.”
Conscientiousness Stands Out as a Predictor of Longevity
Over time, the evidence relating to longevity has converged fairly decidedly on one explicit Huge 5 trait: conscientiousness. For instance, Howard Friedman and colleagues (1993) used persona information from 1,178 men and women concerned in a 70-year longitudinal research initiated by Lewis Terman in 1921. They found that “conscientiousness in childhood was clearly associated to survival in center to outdated age.”
Mining the identical data set, Leslie Martin and colleagues (2007) carried out a potential longitudinal cohort research of 1,253 female and male Californians over seven many years (1930-2000), discovering that “conscientiousness, measured independently in childhood and maturity, predicted mortality danger throughout the complete life span.”
Margaret Kern and Howard Friedman of the College of California, Riverside (2008) carried out a meta-analysis of the affiliation between conscientiousness and longevity involving 20 impartial samples with 8,942 individuals from six completely different international locations. Outcomes confirmed that “greater ranges of conscientiousness have been considerably and positively associated to longevity.”
Reviewing the proof linking conscientiousness to well being and longevity, Tim Bogg (Wayne State) and Brent Roberts (College of Illinois) (2014) concluded that “accrued proof helps better integration of conscientiousness into public well being, epidemiological, and medical analysis, with the final word purpose of understanding how facilitating extra optimum trait standing would possibly foster higher well being.”
Just lately, Nicholas Turiano of West Virginia College and colleagues (2020) built-in information from 44,702 individuals in 12 completely different cohort research to find that “a constant sample emerged of upper ranges of conscientiousness predicting a diminished hazard of dying.”
Why Do Conscientious Folks Are inclined to Dwell Longer?
So, relating to longevity, the trait of conscientiousness seems to be probably the most consequential predictor. However scientists and laypersons aren’t solely interested by prediction; we additionally need to clarify—to know why issues relate in the way in which they do. Past mere description and prediction, explaining the phenomena of the world is the apex of scientific ambition. So, how might conscientiousness result in longevity?
Typically, complicated human outcomes are multi-determined, which implies that persona components might exert their affect on longevity by means of numerous pathways. One such pathway runs from persona to conduct to longevity. Research has documented that persona traits predict sure well being behaviors, resembling smoking, diet, train, alcohol use, and risk-taking, which in flip are identified to have an effect on longevity.
For instance, Sarah Hampson and colleagues (2006) on the College of Surrey in Nice Britain examined academics’ persona assessments of 963 elementary schoolchildren. They then assessed individuals’ smoking, alcohol use, physique mass index (BMI), and self-rated well being 40 years later. “Childhood persona traits have been considerably related to all 4 outcomes.” Increased conscientiousness was associated to much less smoking in maturity and, for girls, decrease BMI.
Shantel Spears (2019) at West Virginia College and colleagues have lately argued that persona might also have an effect on longevity by means of its results on sleep. Their 20-year research involving 3,759 individuals discovered that “decrease conscientiousness predicted elevated loss of life danger by way of the direct, oblique, and whole impact of …sleep period.”
Conscientiousness can be prone to have an effect on longevity by way of organic pathways. Certainly, Angelina Sutin of Florida State College and colleagues (2018) analyzed a pattern of over 12,000 individuals for the hyperlink between organic markers of well being—together with physique mass index, waist circumference, blood markers (A1c, HDL ldl cholesterol, and many others.), and bodily efficiency (lung perform, grip energy, strolling pace)—and numerous correlated aspects (parts) that represent the conscientiousness trait (self-control, order, industriousness, traditionalism, advantage, and duty). Results confirmed “4 of the six aspects of conscientiousness have been related to almost all the well being markers.” Increased conscientiousness predicted “more healthy metabolic, cardiovascular and inflammatory markers, and higher efficiency on bodily assessments.”
Yannick Stephan of Euromov College in France and colleagues (2019) obtained seven-year mortality data from over 11,000 individuals, evaluating the aspects of conscientiousness, in addition to demographic components, illness burden, smoking, and bodily inactivity. They discovered that, controlling for demographic components, the industriousness aspect alone “was related to an nearly 25% decrease probability of mortality.”
Most lately (2021) Páraic Ó Súilleabháin on the College of Limerick and colleagues provided evidence that persona might have an effect on longevity by means of an individual’s immune perform. Their research checked out two organic markers—interleukin-6 and c-reactive protein—identified to consider age-related morbidity in a pattern of 957 adults examined over a 14-year interval. Outcomes recommended that “a part of the explanation why individuals who rating greater on the persona trait of conscientiousness dwell longer is on account of their immune system, particularly on account of decrease ranges of a organic marker referred to as interleukin-6.”
Excessive conscientiousness, then, seems to repay by way of improved longevity by means of a number of behavioral and organic pathways. So, how conscientious are you? A quick Huge 5 trait evaluation may be discovered here. In the event you’re low on conscientiousness, there may be nonetheless hope. One can learn to grow to be extra conscientious by means of purposeful follow. Psychotherapy may assist enhance conscientiousness. Lastly, research has proven that persona basically and conscientiousness specifically can change, and have a tendency to improve with age. So, your low conscientiousness might enhance by itself over time—that’s, if it doesn’t kill you first…
