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.
Max Weber Maximilian Karl Emil "Max" Weber (/ˈveɪbər/;[4] German: [ˈmaks ˈveːbɐ]; 21 April 1864 – 14 June 1920) was a German sociologist, philosopher, jurist, and political economist. His ideas profoundly influenced social theory and social research.[5] Weber is often cited, with Émile Durkheim and Karl Marx, as among the three founders of sociology.[6][7][8][9][10] Weber was a key proponent of methodological antipositivism, arguing for the study of social action through interpretive (rather than purely empiricist) means, based on understanding the purpose and meaning that individuals attach to their own actions. Unlike Durkheim, he did not believe in monocausality and rather proposed that for any outcome there can be multiple causes.[11]
