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.

This research examines how authoritarian and submissive personalities develop through social learning rather than innate traits. Submissiveness often originates from adolescent training in obedience and conventionalism. Conversely, authoritarians tend to be ethnocentric and maintain double standards, often surrounding themselves with like-minded circles. This creates a social bubble where they assume their views are universally held, illustrating how specific environments shape long-term social attitudes.

This work introduces foundational research in personality measurement, emphasizing key issues such as the nature of psychological constructs, as well as the importance of reliability and validity. It highlights measurement approaches that not only assess traits but also advance theoretical understanding of personality. The authors particularly support methods grounded in at least a basic theory of the construct being measured, aiming to strengthen both scientific rigor and conceptual development in the field.

Psychological defense is the process of regulating painful emotions like anxiety and loss of self-esteem, often through unconscious mental processes. While early theories focused on internal conflicts regarding sex and aggression, more primitive mechanisms like denial protect against external reality. Despite a period where 'cold cognition' dominated social psychology, modern perspectives view defenses on a developmental continuum, ranging from simple, early-emerging tactics to more complex, mature forms of self-regulation.

This chapter explores how individuals maintain behavioral consistency by actively selecting environments that align with their traits. This 'person-situation fit' suggests that stability in behavior across time is not just an internal mechanism but a result of people choosing settings where their natural personality can be genuinely expressed. However, the author notes that progress in this field is hindered by a reliance on 'mechanistic interactionism' and traditional laboratory experiments, which often fail to capture the dynamic ways people navigate real-world environments. The central challenge for modern researchers is to develop methodologies that can quantify how personality drives situational choice without abandoning the rigor of conventional empirical investigation.

This review examines the evolution and structure of extraversion, tracing its development from early typological views to modern trait-based models. It integrates foundational theories with contemporary perspectives linking extraversion to affect and personality frameworks. The authors propose a cohesive model outlining its core components and underlying structure, offering a clearer understanding of how extraversion emerges and functions within broader personality systems.

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.

The study of how individuals manage stress has evolved through three distinct theoretical generations. Early psychoanalytic models initially merged personality and coping as one, while the subsequent transactional approach shifted focus toward situational factors and cognitive appraisals. The current 'third generation' provides a more nuanced framework that maintains clear distinctions between stable personality traits, situational coping strategies, and final adaptational outcomes. By refining these operational boundaries, researchers can better understand how specific personality profiles influence the choice of coping mechanisms and, ultimately, long-term psychological resilience.

Research identifies three replicable personality types among adolescents (Resilients, Overcontrollers, and Undercontrollers) that generalize across different racial backgrounds. Resilients are characterized by high intelligence and ego resiliency, leading to academic success and low delinquency. Overcontrollers are also successful but prone to internalizing problems like anxiety, while Undercontrollers face a broad spectrum of academic and behavioral challenges. These findings emphasize that the unique constellation of an individual's traits, rather than just isolated dimensions, significantly shapes their life outcomes and susceptibility to psychopathology.

This meta-analysis of 45 studies identifies hostility as an independent risk factor for coronary heart disease (CHD) and all-cause mortality. Using structured interviews to measure hostile potential yielded a correlation of r=.18 with CHD. Notably, the Cook-Medley Hostility Scale and similar cognitive measures were significant predictors of mortality (r=.16), even after controlling for traditional medical risk factors. While recent high-risk studies have introduced more null findings, the overall data suggests that a hostile personality profile significantly impacts long-term cardiovascular health and longevity.

Holland's typology emphasizes that professional flourishing depends on congruence between an individual’s personality and their work environment. When a person's RIASEC type aligns with their workplace characteristics, they experience higher job satisfaction, stability, and performance; conversely, a lack of fit typically results in frequent career shifts and dissatisfaction. Recent research has further strengthened this model by linking Holland’s vocational types to the Big Five personality factors, such as correlating the 'Social' type with high Agreeableness and Extraversion, providing a more comprehensive psychological map of career success.

This review of 115 longitudinal studies involving 45,000 marriages emphasizes that relationship success is a dynamic trajectory, not a static state. By evaluating decades of data, the authors developed an integrative model showing how individual vulnerabilities, external stressors, and adaptive communication processes interact over time. This shift toward longitudinal analysis allows researchers to better predict marital stability and identify specific turning points where relationships either thrive or dissolve.

This study investigated how different groups—including parents, friends, and strangers—agree on an individual's personality traits. Researchers found that while knowing a person in the same context helps, it is not required for agreement; in fact, acquaintances who had never met agreed as much as those who had. Acquaintances were significantly more accurate than strangers, not because they assumed the person was like them, but because they correctly identified the target's unique characteristics. These findings suggest that agreement between different judges primarily stems from mutual accuracy rather than shared social circles or simple communication.

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.
