Just saw this poll; interesting coincidence that I recently took this test at my workplace, as part of a psychology related training course.
Interestingly, the person who ran the course has worked with some very successful portfolio managers and noticed that most have second letter as N (INTUITION)
I'm an INTJ as well.. too bad this isn't a sufficient condition to being a great investor ;)
Curious if there's a way to find out personality profiles for Buffett and Munger...
