Hm.... I kind of feel like it is the other way around. I see an equal amount of both to be honest, and that has a lot to do with over exaggeration of inferior functions in stereotype descriptions, but still I feel like INTP would be more likely to mistype as INFP than for an INFP to mistype as an INTP.

I see a lot of INFPs typing as an INFJ, INTP, INTJ, ect ect, even ISFP to a much lesser extent. The only type confusion I've really seen pertaining to INTP is an INTP mistyping as ISTP or INFP.... Every once in a while INFJ.

That's just my opinion though, not sure.

 

I see a shitload of INFPs mistyping as INTPs because they're afraid of the stigma of being a Feeler instead of a Thinker, on the false assumption that it relates to their intelligence. It mostly happens with people who haven't bothered learning the functions and rely on the I vs E, S vs N, F vs T and P vs J typing method.

Edit: I also see a lot of INFPs mistyping as INFJs because it's the rarest type and they're special snowflakes (in their mind anyway).

 

Most people will claim INFPs mistype more often because they have a disparaging view of the type (see above post).
I have seen mistypes happen in both directions especially when the individual is an enneagram 4 or 5. Since INTPs are usually 5 and INFPs are more often 4, and 5s are said by enneagram sites to be more likely to mistype as 4 than vice versa, then maybe INTPs mistype as INFPs for similar reasons; those reasons being that they mistakenly think experiencing strong emotion makes you a Feeling type. Since we have no real statistics on it, it's all speculation.

How about not experiencing strong or deep emotions (not just "not showing," but actually not experiencing), except having occasional outbursts under stress? Are any INFPs like that?

 

I have seen a lot of both. From my personal observations, if I had to put it into percentages, I'd say INFPs mistype as INTPs almost two-thirds of the time and INTPs as INFPs a bit more than one-third.

Incidentally, I see both types mistype as the same selection: as each other, as INTJs, INFJs, ISFJs and ISFPs mainly. Some people just take longer to figure it out for themselves - maybe because they're not that introspective, or they're new to the MBTI.

 

I've typed as an INFP every time I take the test up until the last two times I've taken it, when my result was INTP instead. People who don't know me very well often guess that I'm a T, but my close friends say I am an F. I've done my research, and I'd definitely still consider myself an INFP. Sometimes I feel detached from my emotions, and when I'm trying to make a decision I do think about it logically. However, in the end, I go with what FEELS right, what makes me FEEL happy. I try to aim in the middle and go with what would be considered logical and still feels right, but my feelings about something usually (although not always) take a higher priority. I think I'm just really close to the center of the scale between F and T.
