"Openness to experience is one of the domains which are used to describe human personality in the Five Factor Model. Openness involves six facets, or dimensions, including active imagination, aesthetic sensitivity, attentiveness to inner feelings, preference for variety, and intellectual curiosity. A great deal of psychometric research has demonstrated that these facets or qualities are significantly correlated. Thus, openness can be viewed as a global personality trait consisting of a set of specific traits, habits, and tendencies that cluster together.
Openness tends to be normally distributed with a small number of individuals scoring extremely high or low on the trait, and most people scoring moderately. People who score low on openness are considered to be closed to experience. They tend to be conventional and traditional in their outlook and behavior. They prefer familiar routines to new experiences, and generally have a narrower range of interests. People high in openness tend to have more liberal political views, whereas those who are low in openness tend to be more conservative, and are more likely to endorse authoritarian, ethnocentric and prejudiced views.
Openness has moderate positive relationships with creativity, intelligence and knowledge. Openness is related to the psychological trait of absorption, and like absorption has a modest relationship to individual differences in hypnotic susceptibility.
Openness has more modest relationships with aspects of subjective well-being than other Five Factor Model personality traits. On the whole openness appears to be largely unrelated to symptoms of mental disorders. Religious fundamentalism and to a lesser extent general traditional religiosity tend to be associated with low openness, whereas open mature religiosity and spirituality tend to be associated with high openness."
