Openness to experience (or simply openness) is a personality trait and one of the dimensions of the five-factor model of personality, or Big 5. People with high levels of openness are more likely to seek out new experiences, be comfortable with the unfamiliar, and engage in introspection than those who are lower on the trait. Those with low levels of openness can be perceived as closed-minded, and prefer familiar routines, people, and ideas. Openness is positively correlated with creativity—those who are particularly open to experience have been shown to have more active imaginations and a greater appreciation for aesthetics and beauty—as well as some measures of well-being, including overall happiness.
Levels of openness vary by location; within the U.S., those on the coasts are typically rated as more open than those in the middle of the country. Like other traits in the five-factor model, openness is believed to have a genetic component and exists on a spectrum: some respondents score very high, others very low, and most fall somewhere in the middle. Research provides conflicting answers on the question of gender differences in openness: Some studies have found no differences between genders, while others have found significant variation.
However, unlike the other Big 5 traits—extroversion, agreeableness, neuroticism, and conscientiousness—openness appears, based on some large meta-analyses, to have no significant correlation with anxiety or mood disorders.
