who classified personality as extroverts introverts and ambiverts
Extraversion and introversion The trait of extraversion–introversion is a central dimension of human personality theories. The terms introversion and extraversion were popularized by Carl Jung,[1] 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.[2] 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.
Big Five personality traits The predictive power of the Big Five personality traits is robust across life domains: personal, interpersonal, and social or institutional. Recent research indicated that personality traits may be equally strong predictors of mortality (adding as much as five years to one's life), divorce, and job performance as socioeconomic status and cognitive ability.[140] High neuroticism precedes the development of all common mental disorders.[141] However, research in support of this finding is limited and further evidence is required to fully uncover the strength of the predictive power of personality traits on life outcomes. Social and contextual parameters also play a role in outcomes and the interaction between the two is not yet fully understood.[175]
