INTP: I mistyped as it for several years and so did a lot of other people. People still tend to think I'm an INTP and, frankly, they might not even be wrong. I seem to use Si and Ti prominently and, in general, tend to neglect my extroverted functions if we are going with the grant stack form of the mbti and I'm not really "anti-Ne" as much as it's more of a sandbox skill for me, so I can see why people would think it's not my inferior.
INFJ: I mistyped as INFJ for like... 5 years. I fit a lot of the shitty descriptions of INFJ, tunnel vision, farsighted, the 20 year plan spanning well to far into the future, seeking an ideal that isn't realistic or feasible. Being that my senses are shit, interior Se sometimes looks plausible as well from an outsiders view. Shitty descriptions also overhype INFJ's Ti usage. I think a lot of my friends might mistype me as this.
IxTJ: By dichotomy, I tend to get either INTJ or ISTP test wise depending on the day (with INTJ being most often), so realistically while a far ass reach it'd be a close one. I'm no Te user, but I can definitely feign the image, especially at my worst. I actually can fit descriptions of these types superficially, especially when the cognitive functions are ignored.
