Extrovert

The trait of extraversion–introversion is a central dimension of human personality theories. The terms introversion and extraversion were popularized by Carl Jung, although both the popular understanding and psychological usage differ from his original intent. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reserved and solitary behavior. Virtually all comprehensive models of personality include these concepts in various forms. Examples include the Big Five model, Jung's analytical psychology, Hans Eysenck's three-factor model, Raymond Cattell's 16 personality factors, the Minnesota Multiphasic Personality Inventory, and the Myers–Briggs Type Indicator.

Extraversion and introversion are typically viewed as a single continuum. So, to be high in one necessitates being low in the other. Carl Jung and the developers of the Myers–Briggs Type Indicator provide a different perspective and suggest that everyone has both an extraverted side and an introverted side, with one being more dominant than the other. Rather than focusing on interpersonal behavior, however, Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents" (focus on one's inner psychic activity) and extraversion as "an attitude type characterised by concentration of interest on the external object" (the outside world).

Extraversion is the state of primarily obtaining gratification from outside oneself. Extraverts tend to enjoy human interactions and to be enthusiastic, talkative, assertive, and gregarious. Extraverts are energized and thrive off being around other people. They take pleasure in activities that involve large social gatherings, such as parties, community activities, public demonstrations, and business or political groups. They also tend to work well in groups. An extraverted person is likely to enjoy time spent with people and find less reward in time spent alone. They tend to be energized when around other people, and they are more prone to boredom when they are by themselves.
