Interestingly enough I tested as ISTP this time, that's a first. Pretty close to the middle there on the S/N scale, and I have an idea of which answers did it, and I didn't really like how those questions were phrased.
Still, I find it intriguing. I can't help but think that this accurately reflects an underlying change in how I see myself and the world. Some of the questions I know I would have answered differently ten years ago.
