I have come to the conclusion that there are two distinct types of introverts with two very different sets of personality traits. Based on the statements and ideas contained in threads such as these,
it appears that many introverts (not just INTPs) would prefer to be extroverts. In fact, it seems that this may even be the case for over half of the introverts who participated in those threads. Even some of the posters who wanted to remain introverted admitted that they would like to be a little more outgoing. This desire for more extroversion in roughly half of all introverts implies, of course, that the remaining half are happy with their introversion and don't want to change.
Why do we have two distinct sets of introverts? I maintain it is that the set of introverts who wish to be extroverted are, in fact, introverts only by circumstance, and would do well to change their ways. These people are probably shy, unconfident, lacking in social skills or possess some other quality which forces them into introversion, thereby leading them into a realm of depression and loneliness. I see now that I was incorrect in offering the advice of embracing disdain (http://forums.intpcentral.com/showthread.php?t=4255) as an element of an introvert's means of overcoming feelings of misery or self-loathing, because these circumstantial introverts don't wish to embrace disdain and would rather be extroverts, for whom general disdain is probably alien. No, in fact, my advice and encouragement would only be useful for those introverts who enjoy their introversion but who feel social pressure to conform to an extroverted mindset.
As a true introvert, I find the desire to be more extroverted alien. If anything, I would like to be more introverted and have fewer social interactions in the day. What can we do for these poor lost souls (you know who you are!) who wish to be more extroverted and who often feel blue on account of being relegated to introversion against their will?
