Following 1,110 low-income, mostly first-generation Mexican-origin adults for 16 years, researchers found that job loss disrupted the usual maturing of personality. Afterward, people became less agreeable, less conscientious, and less open to experience, and the normal decline in neuroticism stalled. When a spouse lost a job, partners also grew less agreeable and open, but showed an immediate rise in conscientiousness. Declines in agreeableness, conscientiousness, and openness were steeper when the husband was the one who lost work. People who lost jobs also showed less stable overall personality profiles, though effects were small and relative standing on each trait stayed stable.

In a 16-year study of 1,110 Mexican-origin adults, job loss disrupted normal personality maturation: conscientiousness and agreeableness declined, and neuroticism's typical age-related decline stalled. Openness dropped both before and after job loss. Rank-order stability was unaffected, but personality profile stability weakened. A partner's job loss also mattered (especially a husband's), which triggered lasting declines in the spouse's agreeableness, conscientiousness, and openness, though conscientiousness sometimes rose compensatorily.

This PRISMA-guided systematic review synthesized 14 studies (2020–2025) on Big Five/HEXACO traits and vocational outcomes in adolescents. Conscientiousness and Openness were positive correlates of career maturity, decision-making self-efficacy, and vocational identity in several studies, though Conscientiousness's effect often weakened or reversed once RIASEC interests or self-efficacy were added as predictors. Neuroticism (and its HEXACO counterpart, Emotionality) was the most consistent trait, reliably linked to greater decisional difficulty and career self-doubt. Extraversion and Agreeableness showed more selective associations, aligning with enterprising/social interests. RIASEC personality–aspiration congruence varied by culture (moderate in a collectivistic Asian sample versus low in a rural Latin American sample) though this contrast rests on just one study per context.

When people feel more satisfied at work, they gradually become more conscientious and emotionally stable, and those personality shifts in turn make them even more satisfied, creating a self-reinforcing cycle. Two large studies confirmed this goes both ways, with effects building and then fading over time rather than operating steadily. This suggests workplaces aren't just where personality shows up, they're where it develops. Organizations that invest in employee satisfaction may be inadvertently cultivating more reliable, emotionally resilient workers, while employees should recognize that their job choices can fundamentally reshape who they are over time.

This study proposes a Character Model of Scientists (CMS) comprising four dimensions: personality traits, cognitive preferences, values, and habitual behaviors, each containing four elements drawn from a literature review of 24 studies. Big Five connections are explicit: scientists score higher in openness, with conscientiousness and agreeableness (cooperation) also represented. The model links to established Big Five theory, noting personality dimensions are harder to develop through training than values or behaviors.

The Big Five personality factors serve as powerful heuristics for predicting outcomes across multiple life domains. At the individual level, traits are linked to health, happiness, and identity. Interpersonally, they shape the quality of family and romantic relationships. Finally, at the institutional level, personality influences occupational success, political ideology, and community involvement. These findings underscore that personality dispositions are not just internal states but active drivers of significant life consequences.

This study examines the connection between the Big Five personality traits and Holland’s RIASEC occupational types. The findings reveal that while these models overlap, they measure distinct aspects of an individual. The strongest links exist between Enterprising roles and Extraversion, as well as Artistic roles and Openness to Experience. In contrast, the 'Realistic' type showed almost no correlation with the Big Five, suggesting that personality and vocational interests provide unique, complementary insights into a person's profile.

This meta-analysis identifies robust links between Holland’s Big Six vocational interests and the Big Five personality domains. The strongest connections include Artistic with Openness (r=.48), Enterprising with Extraversion (r=.41), and Social with Extraversion (r=.31). These findings indicate that career interests are not distinct from personality; rather, they serve as specific, practical expressions of a person's broader dispositional traits in a professional context.

This study explores how intelligence, personality, and vocational interests overlap. It distinguishes between intelligence as 'maximal performance' (testing well) and 'typical performance' (everyday thinking). By analyzing these connections, the researchers identified four 'trait complexes'—social, clerical, science, and intellectual. The findings suggest that Openness and Neuroticism are particularly linked to how we naturally engage with intellectual tasks and cultural interests throughout our lives.
