Well, I'm here and I know all qualified psychometricians know that MBTI is formally Invalid and Unreliable.
I also know that MBTI was invented by a mother and daughter who had no qualifications at all - and in particular they had no psychometric qualifications and so had no way of making a Valid and Reliable personality test.
Also their test is plaigerised from, "PersonalityTypes", by Carl Jung who was a collaborator in WW II and a guru of the New Age religion.
In fact qualified psychometricians regard MBTI as Invalid and Unreliable as astrology. And all qualified astronomers know that astrology has no truth value.
In fact MBTI is used here simply to reinforce narcissism.

You know... I hate to say it, but I think you might be right. I see all these patterns in people, but I think it's only because I was given the pattern, and then fit all my perceptions into it.
The only reason I haven't rejected it yet is because it's the whole basis for this site. If I reject it, I have to leave, because there's no good reason for me to be here if I accept that it's invalid. Everything I've studied is pushing me towards the idea that it's an incomplete or inaccurate picture. I mean, if you accept the theory and several common extensions of it on face value, it seems to me that my use and awareness of abstract logic should be lower than all NT's, about equal to an average ENFP and INFJ, and higher than all other types. When I met some alleged NT's who seemed clearly less intelligent than myself, I decided to write them off as misidentified ST's... but then it kept happening, and I realized there had to be a better explanation. So I applied various, subtle methods of measuring various kinds of intelligence, and I found little correlation with type (even the ones that were supposed to exist by the very nature/description of the type). And when I examined it closely, I found that the way the theory is applied has so many loopholes and exceptions that you could feasibly use it to justify yourself being any type you wished. People are always encouraged that they're right about themselves, regardless of what type they think they are.
There are a few basic patterns according with groups of letters that you could have predicted from observation anyway, but much more is speculation. Basically, all it really does is confirm our suspicions, rather than explain any new differences between people that weren't apparent.
The problem is, most people don't have access to or interest in the resources they'd need to get a more thorough understanding, so this is the best they can do in furthering it. It does help people in dealing with basic differences in some cases (and that's what I like about it), don't get me wrong. But I think it's more that it shows people how differently they could perceive things, and makes them more open to those who think differently, than anything in the theory itself.
So my question is... if MBTI is invalid, what do we do? Just leave? Give up? What's left here for us? You seriously make me contemplate whether I have any business staying here because of my own doubts about it...
Anyway, do you have any ideas about what might be superior to MBTI?
