Analyzing 213,259 adolescents across 30 countries via PISA 2022, this study found curiosity, perseverance, emotional control, empathy, assertiveness, and stress resistance each positively predicted science achievement, while cooperation showed a small negative link. Curiosity and perseverance were the strongest predictors. These trait-achievement associations were notably stronger in individualist societies, suggesting cultural context shapes how personality translates into academic performance.

When it comes to aging well, diet, exercise, and social interaction may get most of the attention – but researchers are increasingly finding there's more to the story.

This study compared 125 older adults (71–101 years) from Sardinia's Blue Zone versus a nearby non-Blue Zone. Openness, conscientiousness, and agreeableness correlated with better psychological well-being; neuroticism correlated with lower Health-Related Quality of Life (HRQoL). Blue Zone residents showed higher openness, better coping and emotional competence, and more leisure engagement than non-Blue Zone peers, suggesting adaptive personality traits and active lifestyles jointly support successful aging in this exceptional-longevity population.

This Stanford Encyclopedia entry surveys analytic philosophy on wisdom: its relationship to virtue, its epistemic domain, and whether living well is required. It doesn't engage empirical personality psychology directly, but the traits it associates with wisdom map onto Big Five facets: open-mindedness and imagination onto Openness, empathy and perspective-taking onto Agreeableness, and reflective self-assessment onto Conscientiousness. Note: these are just my inferential mappings, not claims made in the text itself!

This paper builds a computational atlas encoding 44 personality models (not just OCEAN) into a shared format, enabling cross-model comparison. Key finding: OCEAN/Big Five models rank third in marginal information value; adding clinical or interpersonal models teaches AI systems more than adding another Big Five variant. Data-driven clustering also reveals 15 semantic groupings cutting across traditional disciplinary categories, offering lexical-level evidence that personality science may have overlapping constructs under different names.

Using large, nationally representative samples from 27 countries (N=143,313), this study finds women score higher than men on Neuroticism (d=0.40), Agreeableness (d=0.35), Conscientiousness (d=0.19), and Openness (d=0.11), with no difference on Extraversion. Gender gaps were largest in individualistic countries for most traits, but reversed for Openness. At the facet level, differences concentrated in one facet per domain, notably Anxiety (Neuroticism) and Compassion (Agreeableness).

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 used eye-tracking with 30 construction workers (extreme scorers on the Big Five) to examine how personality traits relate to hazard-related visual attention in work-at-height scenarios. High-Agreeableness and High-Conscientiousness workers showed the most hazard-oriented attention—longer fixations on critical zones, higher risk-area fixation probability, and the top two Visual Attention Efficacy scores (0.839 and 0.765). High-Openness and High-Extraversion workers displayed broader, more exploratory scanning but weaker focus on high-risk areas, yielding the lowest efficacy scores (0.163 and 0.137). High-Neuroticism workers showed fragmented, unstable attention patterns, landing at an intermediate efficacy level (0.230), consistent with Attentional Control Theory's account of anxiety impairing top-down attentional control.

Study of 139 male Saudi pre-medical students found openness to experience and extraversion positively predicted performance on both academic writing (r=0.292, r=0.171) and oral presentations (r=0.310, r=0.205), while conscientiousness, agreeableness, and neuroticism showed no significant correlations. Writing and oral proficiency were themselves strongly correlated (r=0.500), suggesting shared cognitive processes. Findings support tailoring communication training around personality profiles (fostering curiosity and social engagement) rather than relying solely on traditional academic predictors like conscientiousness.

Survey of 165 Chinese international high school students found clear links between music taste and Big Five traits: K-pop and electronic music fans scored higher on extraversion; those preferring Chinese pop, Chinese-style, and classical music scored higher on conscientiousness and agreeableness; and rap, rock, and indie/folk fans scored higher on openness but lower on emotional stability. The study (a student-authored project using simplified scales) suggests students gravitate toward music matching their personality and emotional needs, with streaming algorithms, fan culture, and exam stress further reinforcing these patterns.

Study of 520 parents and adult children in strained relationships found distinct personality predictors of estrangement for each group. Among parents, higher extraversion (particularly the enthusiasm facet) predicted greater odds of being estranged by an adult child, possibly reflecting expressive, contact-seeking styles that adult children experience as pressure rather than warmth. Among adult children, higher openness predicted lower odds of initiating estrangement, likely due to greater tolerance for value differences and flexible conflict resolution. No other Big Five traits were significant in either group, though higher education also reduced estrangement odds among adult children.

The study found that among 451 Turkish campers, Big Five personality traits collectively predicted both leisure activity involvement and behavioral loyalty (repeat campsite visits). Specific trait-level findings indicated that emotionally stable individuals were more likely to revisit familiar sites, viewing challenges as adventure rather than stress. Conscientious campers favored reliable, safe sites and showed stronger loyalty, while extraverted campers were drawn to socially active settings. Those higher in openness tended toward variety-seeking, potentially weakening loyalty. Agreeableness supported loyalty when group dynamics and service quality were positive. Leisure involvement mediated personality's effect on loyalty, and this pathway was amplified when place dependence was high.

In 116 Indonesian psychology undergraduates, neuroticism was significantly positively associated with academic stress (r = 0.207), while extraversion (r = -0.331), agreeableness (r = -0.346), conscientiousness (r = -0.199), and openness (r = -0.366) showed significant negative associations. Openness had the strongest protective effect. Findings suggest sociability, empathy, discipline, and cognitive flexibility buffer academic stress, while emotional instability heightens vulnerability, extending Western personality-stress research to a collectivist educational context.

In 296 adolescents tracked over two years, student-teacher agreement on Big Five traits was highest for Extraversion (highly observable, low evaluativeness) and lowest for Neuroticism (less observable, more evaluative). Conscientiousness showed stronger agreement for girls than boys. Teachers consistently rated Extraversion, Openness, and (for girls) Neuroticism lower than students' self-ratings. Both personality traits and social competencies showed high temporal stability, with teacher ratings more stable than self-ratings, and agreement remained consistently low across the study period.

This narrative review of 31 studies finds that chronic stress is consistently associated with higher neuroticism and lower levels of the remaining four Big Five traits. The neuroticism link is the strongest and most well-replicated; evidence for reduced conscientiousness is moderate; associations with extraversion, agreeableness, and openness are meaningful but largely cross-sectional. The relationship is likely bidirectional, and social support, coping strategies, and socioeconomic status all moderate these effects.

Wu, Van der Linden, Liu et al. (2026) asked whether creativity is better predicted by individual personality traits or by an overall personality profile. Using 197 Chinese college students, they found that people who score high across all five traits simultaneously (open, conscientious, outgoing, agreeable, and emotionally stable) tend to be rated as more creative by peers and themselves, and perform better on creative thinking tasks. No single trait explained as much as the combined profile.

Aravindh et al. (2026) surveyed 260 retired older adults in Chennai, India, finding that roughly one-third showed problematic or at-risk internet use. Among Big Five traits, conscientiousness was negatively associated with internet addiction while neuroticism and openness were positively associated; extraversion and agreeableness showed no significant links. Younger age, higher education, and prior government employment were also independent predictors of problematic use.

Zavhorodnia and Shepelova (2026) studied 147 Ukrainian university students (mean age 24, 78% women) during wartime martial law. Emotional stability was the strongest protective factor for subjective well-being, followed by openness, extraversion, and conscientiousness. Agreeableness unexpectedly predicted well-being decline, likely reflecting emotional exhaustion from caregiving demands in a predominantly female sample. Openness mediated effects of extraversion and novelty tolerance, and emotional stability moderated openness's protective role.

Wilson and Calanchini (2026) examined how cultural tightness — the strength of social norms and intolerance of deviance — predicts personality at regional levels. Across U.S. states, tighter regions scored higher in conscientiousness and lower in openness. Cross-nationally (56 countries), tighter nations scored lower in extraversion and the creativity facet of openness. Agreeableness, neuroticism, and most conscientiousness facets showed no consistent relationships with tightness.

A 2026 South African study (n=118) found work engagement positively linked to all Big Five traits except neuroticism, which correlated negatively. Extraversion and conscientiousness were the strongest predictors. Basic psychological need satisfaction (especially "joyful connection") explained additional engagement variance beyond personality traits alone. Research purpose: This study investigated the associations among work engagement, personality traits, and basic psychological needs from an organisational neuroscience perspective. Motivation for the study: Few studies have explore...
