Thank you for this verification. When I read about interaction styles it seems like four types seem to fit their descriptions best: INTJ, ENTJ, ENFP, INFP. Also there are four types that make me scratch my head and wonder why they got grouped that way: ISTP, ESTP, ESFJ, ISFJ. I'm not saying that the designation is wrong though. It's just that when I look at the four types INTJ, ISTJ, INFJ, and ISTP, it seems like the ISTP type as a whole doesn't share as much in common as the other three do.Originally Posted by ?
