Being T type you are lesser emotional in consciousness compared to people of F types. It's seen in your nonverbal. In other case I'd type you as F type.
If you'll communicate close with your dual/semi-dual/activator - you'll notice they are significantly more emotional and rise your emotionality higher than you have now.
> my emotions might be more of a subconscious hue, but I am always able to pin them down, understand why I feel this way and how I feel, I tend to monitor my emotional life.
If there are Fe people near you - they may help you to be in better contact with own emotions. But your emotionality generally stays supressed (in consciousness) compared to F types anyway. In Fe types you'll notice the difference easier.
> BUT it might be cultural differences - I know you are from Russia, and Polish people are considered more loyal, devoted friends once you get to know them
I have no basis to think we have significant difference between our nations in this. Our cultures as industrial are close and people are same anywhere. You may think other way because how your TV show Russians, - too negatively because you are in NATO - the organisation made by USA for war against USSR and is kept to hold and control Eastern Europe, 1st of all - Russia which still has serious army power and nuclear forces able to erase USA from the map.
> 1. I don't think I belong to XSTX group - I am not practical, don't make any moves, I am not initiative nor active.
I mistake sometimes in types, but LSI is the most possible from how I've felt you.
Lesser active may relate to introversion and non-types factors as higher anxiety.
> I think that I'm leaning more towards humanitarian causes, occasionally joining some voluntarily activities, trying to help random people out, accomodate groups, love ideas like communism, have strong political views in terms of moral issues etc.
All types may to be socially active and share collective humanistic ideas. Some more often.
If you'll study Russian language, one of serious "alive" communism-like organisations in Russia is "Суть времени" (
Essence of time) by Sergey Kurginyan. I read a little of them and watched youtube
channel (auto-translator may help in some degree).
> 2. What would Se in the creative position look like? I admit that I'm lil bit domineering/aggressive, but not in that obvious, physical way.
mainly S
to understand nuances needs of your own thinking, reading of theory, watching examples of types and intuitive feeling them. ESTJ types are Si but you may also find as "domineering" in some sense. Se rarely shows in rude physical way among adults (it would be illegal)
> I procrastinate a lot (mainly action), I am not risky at all, shy away from taking initiative.
JS types are not risky. shy, overcoming redundant confrontaion - much from introversion
> 3. What would Ne PoLR look like? I pursue many random ideas, without deepening them, consider myself more conceptual than practical, explore many possibilities mentally, have many shallow interests.
Just weak N. Novices to understand clearly nuances in you or other people need higher level of knowledge.
S types have N and may produce ideas, but they base their behavior on such insights in lesser degree compared to N types
Types are balance. It's not like T types have no emotions or S types have no insights, - they have them lesser them thinking and more attention on material world. This balance may be higher or lesser in different people and sometimes to understand what is more in you is not easy. For example, I could not to decide am I extravert or introvert and needed to use IR with close people to understand this.
You don't need a discussions about your type. You need own researching of the typology texts and thinking about it yourself, about your impressions from people of different types. Like I did in past. I've gathered by photos and communication from several experienced in typology people opinions about my type, tried tests, gave tests to people to easer understand their types, read typology books and after ~1 year have stoped on LSE version, which I hold for many years without doubts. You as ST type should do similar - consecutive studding of the subject (books are better, for example by Filatova on amazon) to get systemic understanding of Socionics and use this on yourself and people near you.
So I think we'll close this subject for a while. May others will add something useful too.
