A curated collection of research papers, articles, and related news and media exploring the Big Five personality traits.
Friesen, Rebasso, Chow, and Djupe (2026) surveyed 964 U.S. adults during the 2020 election cycle, finding that more extraverted people enjoyed political activities more, regardless of whether those activities were done alone or with others. Notably, extraverted men got a bigger enjoyment boost from politics than equally extraverted women, especially for activities involving debate or disagreement. Since enjoying politics predicts actually doing it, this gap may help explain why women participate less politically.
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.
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.
