Not ad hominem - I'm criticizing your thought process, and how inadequate it is to handle MBTI identification.
You even admitted yourself, you're not really an INFJ; you and the other INTP/Js are here for the lolz. You also attempted to suggest that you can find a correlation between sentiment mining and MBTI - anyone who knows MBTI and data will know that that is total BS (I have a post grad in research analysis, so yeah, I know something about that) - this demonstrates your lack of understanding of how to intuit MBTI values.
So seeing as how you a) don't really care that you're in an INFJ forum, and b) don't really understand how to measure MBTI in the first place, then you are in no position to criticize my understanding and knowledge of MBTI typing.
I've actually set up a couple based on MBTI - ISFJ/ESFP, and they're engaged to be married. So yeah, I think I know a little about how that works. What have you done?
