Openness to Experience is the strongest personality predictor of political orientation, with high openness associated with liberal/progressive views.
Openness relates to cognitive flexibility, tolerance of ambiguity, and dopaminergic novelty-seeking—all associated with willingness to consider new social arrangements.
High-openness individuals are more willing to question tradition, explore alternative viewpoints, and embrace change. They find cultural diversity stimulating rather than threatening.
Artists, academics, and scientists—professions high in openness—reliably lean liberal in surveys.
Regardless of political views, understanding this link can help bridge divides: conservatives and liberals often differ in underlying psychology, not just values.
