Shared variance in creative self-beliefs: examining self-compassion and personality traits in creative adolescents and adults
Diana MP, Long H, Kerr BA, Gray RC and Harris TP · Frontiers in Psychology · May 2026

Among 127 creative adolescents and adults, hierarchical regression found that openness to experience and conscientiousness were the strongest Big Five predictors of creative self-beliefs, with openness showing the largest effect (β = 0.46). Extraversion also predicted creative self-beliefs once age was controlled. Self-compassion correlated positively with creative self-beliefs but lost predictive significance once personality traits (particularly neuroticism) were included, indicating substantial shared variance.

How much of our personalities are determined at birth?
Laurie Clarke · BBC · May 2026

This BBC article explores how genes and environment interact to shape personality. Twin studies suggest 40–50% of Big Five personality differences are genetic, but genome-wide association studies find only 9–18% heritability—a gap researchers are working to explain. Environmental influences are equally complex: major life events have little lasting impact, while personality appears to be "poly-environmental," shaped by many small cumulative experiences interacting with genetic predispositions.

The character model of a scientist: Structure and role
Jian Zhou, Jian’er Yu, R. S. Dewey · Applied Psychology Research · April 2026

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.

Personality Traits and Agency Politicization: Neuroticism and Perceived Political Control in United States Federal Agencies
Gary E. Hollibaugh, Matthew R. Miles · American Review of Public Administration · April 2026

Using a 2022 survey of 1,306 U.S. federal bureaucrats, this study examines how Big Five personality traits shape perceptions of agency politicization. Neuroticism is the standout finding: more neurotic employees are significantly more sensitive to formal politicization, perceiving greater appointee influence. Conscientiousness shows weaker, mixed effects; Openness, Extraversion, and Agreeableness show no consistent moderating role.

Are your students disengaging – or is it their personality type?
Chathura Sooriya-Arachch · Times Higher Education · April 2026

A study of 72 software engineering students found that roughly one-quarter of "problematic" learners are actually high-neuroticism "delayed starters" (anxious, deadline-driven students who spike activity 67% within 72 hours of due dates). By contrast, high-conscientiousness students showed steady performance, high-agreeableness students engaged 76% more in forums, and high-openness students accessed 3.2× more optional materials. The author recommends milestone-based assessments and learning analytics to better support personality-driven learning differences.

The Relationship Between Emotional Regulation and Social Presence on Impulsive Buying Behavior in Gen Z
Yan Tamara Rosyida, I. Noviekayati, Dyan Evita Santi · Jurnal Multidisiplin Madani · April 2026

Among 121 Gen Z participants in Surabaya, emotional regulation negatively predicted impulsive buying (higher regulation, lower impulsivity), while social presence positively predicted it (more social influence, more impulsive purchases). Together, both variables significantly explained impulsive buying behavior. Findings suggest that strengthening emotional regulation and moderating social media exposure may reduce impulsive purchasing tendencies in this digitally native generation.

Physical attractiveness perceptions in small groups: Associations with extraversion, smiling, and speaking time
M. Bowdring, M. Goodwin, M. Sayette · Perception · April 2026

In 36-minute interactions among 240 strangers in three-person groups, higher extraversion significantly predicted greater perceived physical attractiveness, independently of speaking time. More talkative individuals were also rated as more attractive. Contrary to prior zero-acquaintance research, Duchenne smiling was non-significant. Findings suggest extraversion (and verbal behavior more broadly) shape attractiveness perceptions beyond physical appearance in live social contexts.

Do traits matter for allyship? Exploring personality and character strengths as catalysts for allyship
M. Warren, Michael T. Warren, Erika T.H. Lutz · Equality, Diversity and Inclusion: An International Journal · April 2026

Using latent profile analysis across 3,600+ men from 103 countries, this study challenges the prototype of the extraverted, confrontational ally. "Well-Adjusted" men (high on all Big Five traits, low neuroticism) rated both committed and relationship-building allyship strategies as best-fitting. Character strengths (especially bravery, kindness, and social intelligence) explained additional variance beyond Big Five traits, suggesting allyship training should leverage diverse personalities and strengths.

Personality–AI Fit: How Big Five Traits Drive the Adoption of AI-Powered Financial Robo-Advisors
Jung-Chieh Lee, Jiayi Ren · International Journal of Human-Computer Interaction · April 2026

Using PLS-SEM with 530 Chinese participants, this study models how Big Five traits shape adoption of AI-powered financial robo-advisors via perceived intelligence and anthropomorphism. Conscientiousness, extraversion, and agreeableness positively influenced both AI perceptions and adoption directly; neuroticism negatively affected perceptions, impacting adoption indirectly through anthropomorphism. Surprisingly, openness had no significant effect, suggesting financial decision-making contexts prioritize reliability over novelty-seeking tendencies.

Relationship between personality, resilience, and empathy among dental students: A cross-sectional study
Long-Fei You, Jie Qin, Yuwei Sun · World Journal of Psychiatry · April 2026

This cross-sectional study of 291 Chinese dental students examined how Big Five traits relate to empathy, with resilience as a mediator. Extraversion, agreeableness, conscientiousness, and openness positively predicted empathic concern and perspective-taking, while neuroticism was associated with personal distress. Resilience fully mediated links between empathy and agreeableness, conscientiousness, and openness, and partially mediated its relationships with extraversion and neuroticism, suggesting resilience-building as a lever for empathy training.

Leading Through The AI Divide: Managing Skeptics And Superusers
Megan Malone · Forbes · April 2026

This Forbes opinion piece by executive coach Megan Malone reports on a Truity survey of 56,000+ people finding that Big Five personality traits predict AI attitudes at work. High conscientiousness correlates with enthusiastic AI "superusers" who view it as a productivity tool, while high openness and high neuroticism both predict skepticism: openness due to concerns about creative ownership, neuroticism due to anxiety about risk and job security.

Trajectories of automaticity in physical activity: Associations with personality in a 10-week longitudinal study
Gonzalo Marchant, Guillaume Martinent, Virginie Nicaise, and Julie Boiché · Personality and Individual Differences · April 2026

A 2026 French longitudinal study (n=94, 10 weeks) tracked how exercise becomes more "second nature" (requiring less conscious effort and willpower) over time. More conscientious people developed automatic exercise habits faster; higher neuroticism made it harder to feel in control early on. Practically, building consistent routines matters more than choosing a specific activity type.

Understanding Consumer Responses to Robotic Cafés: A Person–Environment Interaction Perspective
Eojina Kim, Seonwoo Ko, Heesun Park · Cornell Hospitality Quarterly · April 2026

Using Big Five personality traits and Latent Profile Analysis, this study segments South Korean robotic café customers into two profiles: "Mindful Consumers" (higher neuroticism, lower openness) and "Future-Forward Consumers" (higher openness, extraversion, agreeableness). The latter reported stronger emotional engagement and word-of-mouth intentions, especially in fully automated settings. The study demonstrates how trait configurations can predict real-world consumer behavior and inform differentiated service design strategies.

Psychological Steering of Large Language Models
Leonardo Blas, Robin Jia, Emilio Ferrara · arXiv · April 2026

This paper explores whether you can change an AI's "personality" by directly tweaking its internal math rather than just asking it nicely via prompts. Testing across 14 language models, the researchers found that injecting personality signals directly into the model's computations (targeting the Big Five traits) works better than prompting alone, and combining both methods works best. However, the traits don't behave quite the way human personality theory predicts they should.

Why Resilience Is Higher in Dog Owners, and Neuroticism Is Higher in Cat Owners
Edward Clark · AOL · April 2026

A James Cook University study of over 320 people found that dog owners score higher in psychological resilience, while cat owners score higher in neuroticism. Researchers suggest this reflects pre-existing personality traits rather than pet influence: resilient people may be drawn to dogs' structured demands, while those with higher emotional reactivity may prefer cats' independence. The direction of causality, however, remains unclear.

Money Talks: Are Psychopaths Better at Business?
Elizabeth Spiers · Slate Magazine · April 2026

UBC psychologist Leanne Tenbrink discusses her book Poisonous People and research on dark personality traits (psychopathy, narcissism, Machiavellianism, and sadism) in professional settings. Contrary to her hypothesis, hedge fund managers displaying psychopathic behaviors earned less over time. She explains how these traits are overrepresented in leadership, why confident dark traits are mistaken for competence, and how job ads and organizational culture can inadvertently attract and amplify them.

Personality-Driven AI Agents: Operationalizing OCEAN Traits for Human-AI Collaboration in the Coding Domain
Akanksha Garg, Ishaani M, Rafael DeLaPena · Proceedings of the Extended Abstracts of the 2026 CHI Conference on Human Factors in Computing Systems · April 2026

This CHI 2026 paper tests whether Big Five (OCEAN) traits can be embedded in AI coding agents. Researchers created three profiles (a no-personality Baseline, a Cautious Guardian (thorough, risk-focused), and a Decision Builder (confident, exploratory)) and had 14 developers use all three on refactoring tasks. Personalities were reliably detectable without hurting task completion, but preferences diverged sharply, suggesting adaptive personality customization may outperform any single universal style.

Personality Traits and Working Relationships among the Employees of a Public Secondary School
Fregel Lou Prado · International Journal For Multidisciplinary Research · April 2026

This correlational study of 80 Filipino public school employees examined how Big Five traits relate to workplace relationship quality. Employees scored high on agreeableness, openness, conscientiousness, and extraversion, with moderate neuroticism. All four high-scoring traits positively and significantly correlated with communication, trust, job performance, and perceived leadership style. Neuroticism showed no significant relationship with any of these factors, suggesting it is a poor predictor of workplace relationship quality.

Which personality traits are necessary conditions for problematic alcohol use? Insights from a 23-year longitudinal study
Giugovaz et al. · Addiction · April 2026

This 23-year longitudinal study of 306 Belgian participants found that low conscientiousness was the only Big Five trait serving as a necessary condition for problematic alcohol use across all developmental stages, from childhood through adulthood. High conscientiousness acted as a near-complete protective factor: individuals scoring above certain thresholds were virtually immune to developing problematic alcohol use regardless of other traits or life stage.

Personality as Compressed Social Information in Cooperative Partner Selection
Ryo Oda · Letters on Evolutionary Behavioral Science · April 2026

This opinion piece argues that personality traits function as compressed social information, allowing humans to efficiently evaluate cooperative partners. The Big Five personality framework is reframed not merely as a psychometric taxonomy, but as a cognitive shortcut that condenses complex behavioral observations into low-dimensional, easily communicable representations. The author highlights Agreeableness as especially central to cooperative partner selection, signaling reliability through both stable cost structures and heightened sensitivity to social norms.
