Rant.<p>Myers-Briggs is one of the dumbest things in psychology. Psychologists, who generally accept the stupidest theories generally admit it's useless, and Big-5 is much better. It's only popular because it's so value-free - nobody gets offended by any of it's factors (except introversion-extroversion: the only useful one).<p>Introversion-Extroversion is the only factor that is really a big factor. There other MB factors - (Sensing (S) - (N) Intuition, Thinking (T) - (F) Feeling, and Judgment (J) - (P) Perception) are so meaningless nobody even remembers them. The other big 5 factors (Openness to experience, Conscientiousness, Agreeableness, and Neuroticism) are much better descriptors of people. Are you interested in stuff? Openness ++. Do your homework on time? Conscientiousness ++. Say "yes" too much? Agreeableness ++. Crazy? Neuroticism ++. Honesty, intelligence, and empathy could be added; but they are a little prickly to measure. But Big 5 is still fairly descriptive of most people.<p>Personality traits are (roughly speaking) normally distributed. It's stupid to classify people as "extroverts or introverts", as most people are basically just "meh". Sure, there's the geek who never speaks, and the cheerleader, but most people just talk with a few friends, and feel a bit sick when they have to talk to strangers. The dichotomy that's implied by using two classifiers ("extrovert / introvert"), rather than just scoring "extroversion" on a scale of (say) 1-10 is just brain-dead.<p>"Introversion does not describe social discomfort but rather social preference". I like reading books, but in high school I could talk to anyone except a hot girl. Now, I guess I would prefer to read than make "connections", but that doesn't totally disqualify me for having a job that requires a lot of communication. Of course, I'm quite good at jobs that require a bit of thinking, and enjoy them more. So, um, I guess I won't be selling Avon any time soon. My loss, I guess.<p>And who says introverts aren't successful? I would pick Warren Buffet, Bill Gates, Larry Page, Allan Greenspan (yeah, he caused the crisis, but virtually no-one else new better), David Letterman, and quite a few other successful people as un-extroverted people. Possibly Barack Obama, and quite a few other presidents too (but I know next to nothing of US history). Maybe Bob Dylan. Possibly John Lennon. Not Ringo though.<p>Having "social skills" can be important. But not all extroverts have them (think - the bully, Mr. Foot-in-mouth, and the guy who just won't shut up), and most introverts have adequate social skills. Most people do.
