So, I have an introverted and extroverted thread currently active. In it, I found something called the MBTI test(I know, it's common knowledge ), and discovered that my personality type is INTJ. I did some research, and the characteristics for that type perfectly describe me, even the negative ones. Obviously it would be more accurate if you had this test administered professionally, but I found a free version on the internet that might determine your type. http://www.humanmetrics.com/cgi-win/jtypes2.asp. I had some of my friends also take this test, and we are all IN_J, which are supposed to be rare types. Is there any verified evidence that 'birds of a feather' do flock together? Anyway, please vote in the poll if you have taken the test. Here is the result for the U.S population. Let's see how the forum compares!
