first of all Sol is russian. socionics is in his blood. second, expertise in socionics seems to primarily correlate with longevitiy, since people either quit or stick around and since there's no truly objective means of judging accuracy, there needs to be something to hold things together. its like is someone going to learn from someone who is no longer here, what about when they absorb everything, do they move on too. eventually the only continuity and therefore coherence is in a person sticking around. like an oral wisdom tradition. thus sol has a kind of prestige simply in virtue of experience and effort which in lieu of anything better counts for more than nothing. im only half joking with all of this
