Exactly. She means what she means and words means what words means not what you would like it to say, subjectively.Any phenomenon is viewed by him as part of certain existing system, that is regulated by certain patters and laws and a certain logical order, understanding which the LSI considers to be his obligation.
Perceiving his surrounding reality from the point of view of its systematization, logical design, and coherence, the ISTj is constantly analyzing the systems existing around himself - the system of logical and ethical interrelations, the systems of social structures, the system of views and opinions, the systems of life values.
So I don't know what kind of interpretation you could give to these words.
I should suppose that any phenomenon means to you "some phenomena" and it means that socialization is excluded by fact. Ok.
In other words, LSIs value social systems and systematization of their surrounding reality, but dont value what society values, like for example, having a decent social life or having a nice car. Ok.
The systematization of their surroundings can't include systematized friendships and acquaintances either. Ok.
The social life of ppl doesnt make them know what role they play in society as a system or in micro systems (like school,work or groups etc). I don't know why you associate chit chat with friendships or anything either, btw.
And finally you are right. Strat can be very impartial sometimes, especially in the relations descriptions. However, in terms of describing types behavior its pretty valuable.
