Self report testing is flawed and unreliable. It relies on your self knowlege. People often do not understand themselves shrug most likely because the conscious self you experience is just the surface lvl of the mind, which mind you is not readily acessibe.. e_e because your mind isn't your brain. These classifications are theories attempting to make sense of why ppl differ, why certain patterns persist in how they interpret and act on information.
:P so with that said, the abstract model may be flawed and the methods used to see if you fit the model are certainly flawed. regardless its fun to think about, at least for me. The tests however are in large useless. You can test INTP now and in a few years some other type. I wouldn't rely on it, they merely sell it to make a buck.
There however is no solid ground to really hold onto, not even in the "hard" sciences... which is why probably the very idea exites me as someone who prefers the open ended & ever changing.
Yes, it's very straightforward but ultimately you aren't going to experience someone breaking down your character with all the information at their disposal. Self-testing is unreliable, but so is testing by a pyschologist, or by another person. My closest friends are INTP and INFP, I express a lot of disparate ideas and fields of interests. I'm introverted based on the fact I feel most comfortable infront of my computer screen, I don't seek socialising as 99% of the time it's people inviting me out. I keep distances from groupthink and its mob functionality so I rely on intuition in almost all cases, I question everything that's said to me, the intent of that information, the accuracy and if they understand the meaning of their words.Self-reporting?
I think a lot, I feel less: The only confusion here is I don't let my emotional side out, but when I take the plunge I can get emotional but that'a a product of a lack of exposure. If someone comes to me for advice, they're not going to get an emotional pat on the back that maintains the irrationality of their delusion to go back to their ex, or anything of that caliber. I think of practical situations in almost every situation, except with the proclivity to not be regimented to a cold individual who has never tried to interpret others because it's not natural to him, I develop in areas which I feel I lack. Emotions is certainly one of them, but these emotions are usually ephemeral and irrational, often based on complexes like wanting something because I can't have it (stop seeing a girl before the fantasy hasn't been satisfied, for example a romantic trip.)
Lastly, I'm prospective because I gauge a lot of topics that have little crossover, dipping my toes into here or there but not committing to one domain.
And who's to say I don't have self-knowledge of myself? I've questioned every facet of my behaviour, changing weaknesses into strengths, genuinely taking a look at myself, why I'm interested in x, why I behave like this in situation y. I used to have depression and implemented a multi-faceted system of supplementation (oxytocin, 5HTP), exercise, anti-inflammatory diet, sleep. I feel a certain emotion around others, I explore that, understand what's the association, why do I find them attractive and why I'm drawn to them. I constantly question why I do these things, more so than another psychologist would ever be able to because I'm honest with myself when it's needed.
Y'know I've always wondered why people omit self-reports as if they can't be valid. I'm not trying to get people's recognition for being a personality type, it was a task I done to assess my behaviour. With that in mind there was no benefit of deception, practically speaking so I was honest with myself. It was for myself so there was no guilt, shame or objective that would require deception.
Well how about exaggeration? Well, that's a possibility and can be situational based on memory of current affairs, but I took the test nice and slow it wasn't a race for time.
I've consistently scored INTP/INTJ, INTP a few times and INTJ once. Based on 4 Tests The first few domains have not changed, even across time frames. I get an INFJ when I was 17 or something, but I attribute that to the lack of knowledge of the self and an overestimation of ones characteristics.
I don't rely on it, I use it as a model framework. Infact, it seems you rely on the functions quite a lot. While I'm sure you have room for categorical overlaps, you think of these concepts empirically. I'm doing literally the exact same as you, I take the classifier and use that to assess typical expected behavioural patterns, note is type indicator (typicality). Again, it's a closed book, It's not a concrete subject they're just models to represent information.
