What's your personality type?
Personality theory is an interesting class. There are so many ways to define and assess personality, and no, the class is not so much about all the popular personality tests as it is studying the theorists and theories behind personality. The Meyers-Briggs is an interesting test, and I've actually taken several versions of it. It's based on part of Carl Gustav Jung's work. My results have been pretty darn consistent, even though the tests sometimes seem quite different from each other. I always turn out as either INFP or INFJ, with clear preference for introversion over extroversion, but very little preference towards either perceiving or judging (which is the part that was not part of Jung's typology). Descriptions of either of those two types fit me quite well, and one thing that stands out in both of them is a tendency to have good writing ability, which is something that I have been told that I possess.
INFP - "Questor". High capacity for caring. Emotional face to the world. High sense of honor derived from internal values. 4.4% of total population.
