I could be a 5w4, or a straight up 5. I relate more to the type 5 Ennegram description than to the INTP description, although there is much I relate to there as well (obviously).
A lot of INTPs can be type 9s, but I'm too direct and aggressive for that tag. Not to say that 9s aren't aggressive....they are often passive aggressive, which drives me nuts.
I have a hard time trusting people who say they never get angry. My first thought is usually, "Oh, I get it! You punish people by withholding and other passive aggressive shit." Meh to that.
