Myers-Briggs used to annoy me because there were always a lot of questions I could go either way on. The third time I took it I figured out what to do. I divided my answers into two columns. Anytime I had an unambiguous answer, I'd put it in both columns, but if I felt split I'd put opposite answers in each column. I was curious as to whether this would yield interesting results, and it did: I got a 50/50 split in two of the variables (that is, I'm evenly matched in IE and TF), and an extreme bias in the other two (I'm about as N and P as you can get). This matches how I feel about myself pretty well. I found another amusing way to verify the approach: if you combine the opposites to my extremes you get SJ, and the SJs turn out to be my arch-enemies. I read the description of SJ and it makes me squirm and think, why would anybody be like this? These people are neurotic bureaucrats. The world would be better off without them!
Edit: I'm joking, of course. SJ is so much my polar opposite that I have a hard time understanding or empathizing with them. I just find it ironically hilarious to read a typology that's designed to foster understanding and find myself dismissing 1/16 of humanity as basically adding no value.
Edit 2: As of this moment, the SJs are less than 3% of the respondents to the poll. Evidently I've come to the right place. :)
