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.

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.

Using German panel data and a job search and bargaining model, this study finds that Big Five personality traits shape wages and employment through multiple channels. Higher conscientiousness and emotional stability raise earnings and shorten unemployment for both sexes, while agreeableness reduces wages and bargaining power. Women's tendency toward higher agreeableness and lower emotional stability accounts for roughly as much of the gender wage gap as differences in work experience do.

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 longitudinal research reveals a reciprocal relationship between personality and professional life during the transition into adulthood. While personality traits at age 18 significantly predict both objective and subjective work experiences by age 26, the reverse is also true: early career experiences actively shape personality development. Most notably, the study identifies a 'corresponsive' effect, where the same traits that lead an individual to choose a specific career path are further strengthened and reinforced by the demands of that environment.

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.

Drawing from the longitudinal Intergenerational Studies, this research proves that personality and cognitive ability independently drive career success. Conscientiousness consistently predicted both job satisfaction and higher income, while Neuroticism hindered extrinsic achievements. Furthermore, general mental ability was a primary driver of status and earnings. While adulthood traits are more predictive, childhood personality still contributes unique variance to lifelong professional outcomes.
