I'm a 6w7, and I keep thinking that I'm an introvert, which might be because I am, or I just have an introverted enneagram, I seriously don't know. An ENTP 5 would probably easily be mistaken for an INTP, most of the INTP traits seem to line up with enneagram 5. I think the 5 and 6 ENTPs are less likely to be as assertive too, 5s being the least assertive. The only ENTPs I don't really have a feel for are the 3s, apparently they should have a few more judging traits than the normal ENTPs, they'd probably nearly mistake themselves for ENTJs, I think substitute might be a 3, I can't remember, Entropie and CJ are 3s too... well, probably. I think the 3s are kind of rarer.
I'm a 3w2...What can I answer for you?
