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 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 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.

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.

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.

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.

This longitudinal study followed a cohort of gifted children across several decades to determine how personality and family stress impact longevity. Researchers discovered that psychosocial factors, particularly impulsive or undercontrolled personality traits and the experience of parental divorce during childhood, serve as significant risk factors for premature death. These early-life stressors and traits also linked to unstable marriage patterns in adulthood, suggesting that long-term health is deeply influenced by the intersection of individual temperament and stable family environments.

This study connects James Marcia’s four identity statuses—Achievement, Foreclosure, Moratorium, and Diffusion—to the Big Five traits. Researchers found that Identity Achievers exhibit high Conscientiousness and Extraversion with low Neuroticism. Conversely, Foreclosure correlates with low Openness, while Moratorium and Diffusion involve higher Neuroticism. These findings demonstrate that our psychological 'status' in developing a self-identity is deeply linked to our underlying personality structure.

This meta-analysis explores how the Big Five personality traits predict success across various career fields, such as sales, management, and law enforcement. The research identifies Conscientiousness as a universal predictor of high job performance regardless of the occupation. Other traits are more specialized; for instance, Extraversion is essential for roles requiring social interaction, while both Extraversion and Openness to Experience are key indicators of how quickly an individual will master new training.
