I've never been anything other than an INFJ. I'm fairly comfortable with that stereotype most of the time, except when people decide to view the NF temperament as a whole and end up accusing me of things I don't do just because INFPs, ENFJs, or ENFPs do them.
I'd never really be willing to change my type. The closest I ever got was removing it from my profile. I've invested quite a bit of thought, argument, and several ideas about myself into this type. At this point, if I somehow become 100% convinced I wasn't an INFJ, I'd probably find it easier to leave the forum than admit to everyone that I'd been building on the wrong idea of myself for the past 3 years. :blushing: I mean, I've literally developed and defended prejudices about other types relative to my perception of my own, made friends and enemies of people based on their type, pushed people out of and into my own type because of traits they possessed that I related to or didn't relate to, so... let's just say it would be a little messy for me.
Luckily, I have thousands of excellent, eloquently worded rationalizations at my disposal to defend against any possible argument someone might make against my type, due to the theoretical, subjective, and rule-based nature of this system, so that's not likely to happen anytime soon!
