> Not once have I read an article that discusses introversion and extroversion as flexible personality traits. Myers-Briggs assumes that people have "types", which is not very nuanced. Anything which references Big Five Personality Factors is IMO better (http://en.wikipedia.org/wiki/Big_Five_personality_traits http://en.wikipedia.org/wiki/Big_Five_personality_traits). It also has better traits (or types) - it's quite useful to think of people having a certain level of Introversion, Conscientiousness, Openness to experience (aka inquisitiveness, previously known as "culture" but that's not PC), Neuroticism and Agreeableness. All those traits are interesting. The main advantage of Myers-Briggs seems to be that its traits are all value-neutral (while Openness to experience is basically good, and Neuroticism is basically bad), and the Keirsey Temperament Sorter claims it can sort you into career bins (like "Fieldmarshal" or "Healer"), and compare you to famous people whos behavior seems "consistent" with that personality type. Perhaps someone should write some book classifying historical figures into Big 5 categories.
