There may be many different systems of classifying personality types, but the standard evaluation that I came across again recently was the Meyers-Briggs four category assessment from various questions and/or a survey. My classification on this was what I had previously remembered, and it's pretty darn accurate, with some nuances of course. It made me wonder if a lot of the posters here have similar personality types, given how we see the world and value certain things. Do you think this MBTI thing is accurate? Do you think the predictions of matches within it, male or female, generally work? I wonder how you all might weigh in on this topic.
