A. People are gonna be all like "Stereotypes are silly and can be misleading when you're learning the theory," but regardless:
B. When Wikisocion stops being down (down at the time of writing
http://www.wikisocion.org/en/index.p...ikisocion_home) you'll find some interesting social roles. I found these somewhere:
Common social roles (ILI/INTp)
1. The computer geek who lives in virtual reality and understands computers and Internet communication, but is at a loss for how to act in real-life social situations.
2. The mystic or spiritual philosopher who is into all things mystical, esoteric, or eastern and makes little sense to the material-minded.
3. The encyclopedist or librarian type who knows literally all there is to know about vast areas of knowledge, but does not use his or her knowledge at work.
Common social roles (ILE/ENTp)
1. The lawyer who will argue about anything with anyone, making no distinction between logic and rhetoric.
2. The clown with a spontaneous and often critical wit.
3. The outgoing nerd who makes jokes about things like parabolas and wears things like fishermen's vests to work and to parties because all the pockets are convenient for holding stuff.
Common social roles (LII/INTj)
1. The lone repository of truth — the last stalwart in a crazy world of illogic and delusion.
2. The self-sacrificing workaholic who works so hard not to earn money (usually underpaid anyway), but because he doesn't feel he deserves to slow down and give anything less than 100%.
3. Mr. or Ms. Literal, who says exactly what (s)he means, and trusts that you will too.
C. On the subject of LIIs, I think some common buzzwords are "concept-constructing" and "optimise". The former because we love to create solid theoretical structures which explain things well, and try to make it as universal or widely applicable as possible. Think Kant or philosophy in general. The latter because I often find optimising and doing things not inefficiently to be more important than have the greatest impact as possible. I'd rather spend time tinkering with a system -- say reading my emails or managing work -- than be out trying to accomplish more business.
D. Finally, we should remove the "Rational, Extrovert, Ethics" part of the stereotypes. I think it adds cognitive load because you have to read it and it primes you to think from a socionics theory POV, not a "how do I stereotype this type" POV. Also, no way are EIEs the everyday form of "rational".
