On MB tests I usually test as an IXXP.
(S)LE.
5 and 6 come up often.
quite so.
I haven't learn't MB theory. And I guess you need to learn it if their definitions of S, N T and F functions or other stuff are wrong.
others often type me as 6 or some Fe enneagram type I guess. as for socionics, here, most type me as SEI, few as ESE, couple as LII, couple as ILI, one or two EII, one IEE, one or two SLI, several said IEI, a couple SEE, noone said SLE lol, a couple said a possible EIE, a couple mentioned LIE, that's about it I guess.
*EDIT
ne socionist typed me as ESI, one LII, and finally one SEI.
