Same thing happened with me in the Enneagram. I went something like 8-1-8-3-8-5-8-6-8-6-7-8. I always refer to the type that I started out with, because it was good then, and it's good now. No matter how one might divert, one will always return to their true type, unless they made some original fuck up of a mistake because their skills of introspection were so poor, and so they apparently stayed settled on a type which was not their original typing; that is, they settle on their 'true type'.
Reply to this if you want, but if not, I really don't give a shit, because right now, I'm confused. I'm confused because socionics is so unformalised that I have no fucking clue what is right and wrong, so I can judge absolutely nothing.
