I used to use pedantic as an all purpose insult too but it's a kind of Darren-move. Pedantic people often know specifically what they are talking about so they deserve to zero-in on the issue at length, that is a big part of what intelligence actually is. It's hard for some things to be explained bluntly, because reality is complicated.... if you are not seeing how it relates to real reality then you want an idealized fantasy version of something rather than the true, scientific explanation. yes, pedantic people can stereotypically come across like arrogant and insufferable know-it-alls- but real experts are also often very good at understanding what they don't know yet vs what they already do know.
I don't know about model G, I just think socionic has intertype relationship theory are kind of all wrong/half-baked and is a kind of bastard theory of the original functions. I think on surface it sounds deeper and more prettier than mbti- but that's an illusion, and the real thing is like a mental 50% ghost. It amounts to nothing. Socionics attempt at explaining interpersonal relationships comes across like a bad soap opera where everybody is acting and larping but deep down none of these characters really feel anything for anybody- they are just following a script. Typology is just another way of larping. It's not who you are- the same way Robert Reed wasn't really a heterosexual family man.

I used to credit socionics for having a much better intertype relationship theory than mbti but attundial psyche's intertype relationship theory is light-years ahead of socionics.
"the biggest socionic forum in the west" - but realistically, westerners like me can't do much with socionics and getting into mbti is what helps you with the career stuff no matter how much you whine about how 'shallow' it is. Socionics is too communist like, but it can't even do communism right. If you don't get why people are pissed off at the entire thing, it's like you don't have much of a heart- and I've always had a big heart.
My interest in socionics was mostly cultural, I think. I probably had ancestors who were russian despite the fact that I am big on self-expression [[I mean at least in idealized theory]] and russians are stereotypically cold and straight and Fi-like. (even the Fe valuers!) When I was a wee lad, people said that I looked like a little russian baby. So my interest in socionics was probably to be expected. Plot Twist: My great-great-great-great-great (lots of greats) grandfather was the Idea of Gulenko!
People got the Fi of socionics all wrong- and somebody who has 4D Fi whether I'm EII or IEI- it's irritating. In a vacuum I think Gulenko understands socionics pretty well, but as soon as he starts to put together the Fi puzzle though he (and many others like him) fall short. Look at how often he projects his wife into other people. He seems like a smart enough guy to know what projection is, and to try and avoid it in his professional work - but he does that. Then he says 'IEIs are intrinsically vulnerable' and people & incels like Alive foam at the mouth that they aren't the only weak ones. But that's the thing- I don't disagree with him that IEIs have an innate vulnerability that others don't have... the intuitive functions bring about sensor and logical/physical weakness, weak against the 'harsh real world' etc; and the sensing functions bring about relational and spiritual/magical faggy weaknesses. "I'm a jerk and deep down I care that I'm a jerk!" This part I think, socionics understands & can explain well- but how it pieces together other information + how people interact or how people think they can gauge behaviors is where I don't agree with it and think that it lacks usefulness.
