This research clarifies that altruism and antisocial behavior are independent dimensions rather than opposite ends of one spectrum. Altruism is primarily shaped by familial environments and positive emotionality, while antisocial behavior stems from genetics and negative emotionality combined with low constraint. Because these tendencies arise from distinct etiologies, they can coexist within an individual, functioning as uncorrelated personality expressions rather than mutually exclusive traits.

This longitudinal study identifies three distinct pathways to positive mental health in women, categorized by their levels of Environmental Mastery (EM) and Personal Growth (PG). Achievers excel in both, while Conservers prioritize stability and mastery, and Seekers focus on continuous self-development. Each group exhibits unique strengths in competence, wisdom, and generativity, with their late-life mental health outcomes being significantly shaped by their personality at age 21 and identity formation by age 43.

This study of 220 undergraduates confirms that Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) stem from distinct personality foundations. While both predict prejudice, they reflect different psychological profiles: RWA typically aligns with high Conscientiousness and low Openness, whereas SDO is more strongly associated with low Agreeableness. These results highlight that the motivation for intergroup bias varies significantly between those seeking social stability and those seeking group-based hierarchy.

This longitudinal study analyzed the early-life autobiographies of 180 nuns to determine if emotional content predicts longevity. Researchers discovered a powerful inverse relationship between positive emotions expressed at age 22 and mortality risk between ages 75 and 95. Those in the highest quartile of positive emotion lived significantly longer, showing a 2.5-fold lower risk of death compared to the lowest quartile. These findings suggest that a positive emotional baseline in early adulthood serves as a long-term predictor of survival decades later.

This meta-analysis synthesizes a century of research to clarify how the Big Five traits drive career success. The findings confirm that Conscientiousness is the most consistent predictor of high performance across all jobs. While Emotional Stability also generally predicts strong work habits, traits like Extraversion, Openness, and Agreeableness are more specialized, predicting success primarily in specific roles or niche performance criteria rather than overall job proficiency.

This study investigates how personality determines social status within groups like fraternities and dormitories. Researchers found that Extraversion is a universal predictor of influence and respect for both men and women. In contrast, high Neuroticism specifically predicted lower status in men. While physical attractiveness contributed to status for men, it did not have the same effect for women, whose social hierarchies proved just as stable but took longer to establish.

This study examined how personality traits and emotional tendencies relate to relationship satisfaction in married and dating couples. Both self- and partner-ratings of an individual’s personality showed similar predictive patterns, with positive and negative affectivity emerging as key influences. Traits such as conscientiousness, agreeableness, and extraversion were also linked to satisfaction, while a partner’s personality had a comparatively smaller impact on overall relationship quality.

The emergence of positive psychology marks a fundamental shift from a 'disease model' (which focuses exclusively on repairing pathology) toward a science of human flourishing. This framework emphasizes the study of positive subjective experiences, individual traits like courage and wisdom, and institutions that improve quality of life. By focusing on strengths such as optimism, hope, and self-regulation, researchers aim to understand what makes life worth living rather than merely how to treat mental illness. This proactive approach suggests that building internal resilience and fostering talent are essential for preventing future pathologies and allowing individuals and communities to thrive.

This study identifies 'isms' as the foundational building blocks for measuring social attitudes, revealing a distinct structure of individual differences. A primary three-factor model emerged, with Conservatism and Authoritarianism functioning as major subcomponents of the largest factor. Notably, these social attitudes are largely independent of standard personality domains, with the sole exception of a significant correlation with Openness to Experience. These findings provide a new, content-valid benchmark for mapping belief systems outside of traditional personality frameworks.

This research supports the bidimensional model of acculturation, arguing that maintaining one's heritage culture and adopting a mainstream culture are independent processes rather than opposites. While the unidimensional view suggests an inverse relationship, data from diverse ethnic samples show these two identities can coexist. This flexibility allows for unique correlations with personality and psychosocial adjustment, making the bidimensional approach a more valid framework for understanding how individuals navigate multiple cultural identities.

Research involving over 150 longitudinal studies demonstrates that personality trait consistency increases significantly as individuals age, following a clear upward trajectory before stabilizing. Correlation coefficients rise from .31 in childhood to .64 by age 30, eventually reaching a plateau of .74 between the ages of 50 and 70. These findings suggest that while temperament in early life is relatively fluid, adult personality becomes increasingly 'set' over time. Furthermore, the length of time between assessments negatively impacts consistency, confirming that personality remains most stable over shorter intervals in later adulthood.

This research identifies five robust dimensions of spirituality that constitute the Expressions of Spirituality Inventory (ESI): Cognitive Orientation, Experiential/Phenomenological, Existential Well-Being, Paranormal Beliefs, and Religiousness. While these dimensions correlate differentially with the Big Five, they remain conceptually unique. This suggests that spirituality represents a significant domain of human personality that is not fully captured by the standard Five-Factor Model framework.

This research confirms a robust relationship between Extraversion and pleasant affect, finding moderate to strong correlations across various assessment scales. However, the method of measurement significantly impacts the results. Global, retrospective reports (where individuals recall their moods over time) yield higher correlations than 'on-line' assessments, such as daily diaries or moment-to-moment reports. These real-time methods produce lower, more consistent correlations, suggesting that the Extraversion-happiness link is partly influenced by how people cognitively summarize their emotional experiences.

This study of leaders across 200 organizations found that Extraversion and Agreeableness are the strongest predictors of transformational leadership behavior. While Openness to Experience showed an initial positive correlation, its impact vanished when controlling for other traits, and Neuroticism and Conscientiousness remained unrelated. Interestingly, broad personality domains predicted leadership better than specific facets, and transformational behaviors significantly improved leader effectiveness even after accounting for transactional styles.

This study of 343 participants highlights Conscientiousness as a vital predictor of health-conscious behaviors, particularly those involving household safety. High levels of this trait led to more restrictive smoking rules at home, suggesting that self-disciplined individuals are more proactive in protecting their environment. Interestingly, perceiving health risks only reduced smoking within the home for those high in Conscientiousness, indicating that personality acts as a necessary catalyst for turning health concerns into actual lifestyle changes.

Successful identity consolidation involves committing to adult roles and constructing a coherent sense of self. Research on women shows that ego-resiliency at age 21 predicts better identity outcomes by age 27, a process often mediated by the quality of their experience in marriage. Notably, achieving a stable identity further boosts resiliency. This highlights a dynamic loop where personality resources help navigate social contexts, which then fosters long-term personality growth.

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.

Meta-analytic research spanning 85 years identifies General Mental Ability (GMA) as the premier predictor of professional success. Pairing GMA with integrity tests or structured interviews yields the highest predictive validity (up to .65), effectively measuring both cognitive capacity and behavioral reliability. These combinations offer substantial practical utility for hiring, providing a robust, scientifically-backed framework for selecting high-performing employees across all experience levels.

This meta-analysis of 137 personality constructs identifies how specific traits drive subjective well-being. While personality strongly predicts life satisfaction and happiness, it is less predictive of negative affect. Within the Big Five, Neuroticism stands as the primary predictor of overall satisfaction, while Extraversion and Agreeableness contribute equally to positive affect. These findings suggest that emotional stability and social connection are the foundational pillars of long-term human happiness.
