I decided to look over the existing LII descriptions (here and elsewhere) and rate them.
Full-length LII descriptions:
Short LII descriptions:
Socionics.ua, Prokofieva and Kuzmina
Bukalov and Boiko
Meged and Ovcharov
As you can see, in general the Russian descriptions are quite bad. Weisband's description essentially describes an LII as an LSI, and this understanding "infected" many of the earlier descriptions. The best Russian ones were Gulenko's (the classical one online, not in the Model G book) and then Zamanskaya's. I don't know how Gulenko's other descriptions are, but it seemed to escape the old misconceptions essentially. This is his own type after all. Reinin's was possibly even worse than Weisband's, it's indisputably portraying an LSI. Strat was almost as bad, portraying a Beta introvert at times, but maybe more IEI because it also had weak-Se things. Beskova's male description seemed to be portraying an LSE at times. The female one was better but more abbreviated.
The wikisocion "composite" description is quite good; I helped write it but there are things I would change if I was writing it again. (For example, some Fe things are miscategorized as Fi.) I don't know why they were renamed "composite" - they are original descriptions.
The WSS description (which had input from the community, not just Jack) is the most comprehensive and accurate, but still has a few things I don't agree with - here are my comments:
Ti: decent if a bit overdramatic
Ne: asking lots of questions yes, but nosy? what?
Fi: "personal ties are by no means a point of precedence for the LII" is arguably an exaggeration but the follow up is more accurate. "Always" is not a word that should be used in type descriptions, and particularly for the role function.
Se: basically fine, but the last sentence is out of place and not right: "Occasionally LIIs may be sceptical towards the social machinations of others, believing that people are going to gang up on them and try to force them to do something that contradicts their principles." LIIs are really not the paranoid types, that's an Ni valuing thing.
Fe: some parts are good but again:
"may just as easily fall into inopportune bouts of depression that can be inconsiderately expressed to others" - not really, LIIs tend to internalize their negative emotions, especially long-term ones
-doesn't emphasize social inclusion enough.
"appreciate engaging, charismatic individuals" - engaging yes, charismatic less so
Si: the beginning is confusing, but overall this section covers a lot of good points behaviorally at least. Still, talks too much about aesthetics and enjoyment rather than emphasizing convenience and optimizing one's environment, and comfort. Dress also has to do with Se and Fe - "Sensing" is just a bad name in general for Si.
Te: also a bit overdramatic, may not apply to all LIIs
Ni: Doesn't emphasize foresight and criticism enough, ends up talking about Ne and the negation of Ni too much. Also doesn't mention self-doubt.
Also, no way is Albert Speer LII.
Note: I didn't really look at their other descriptions (except for WSS and wikisocion's which I read a long time ago) - Reinin's other ones seem somewhat better, and Stratiyevskaya seems somewhat better for Se valuers. But I do think that WSS and Wikisocion will probably be the best on the whole.
