@IrisShadow Sounds like we might be pretty similar.
For those of you who are confused about your types, try looking at the cognitive functions and then eliminate the ones you don’t use: http://www.cognitiveprocesses.com/Cognitive-Functions/index.cfm
Personally, I think examining the cognitive functions is the best way to help determine which type one actually is, after mbti tests have narrowed down the options.
For example, an INFP uses completely different cognitive functions than an INFJ: Fi>NE>Si>Te vs. Ni>Fe>Ti>Se. They really aren’t that similar cognitively, so it should be relatively easy to rule out one or the other. Although the INFP is labeled as a “perceiver,” it actually leads with a judging function (Fi). The only reason it is a “p” instead of a “j” is because the judging function is introverted. The exact opposite case is the INFJ, which, while labeled a “judging” type, actually leads with a perceiving function (Ni).
