So I had my dad typed LII and my mom typed ESI, which would make them Super-Egoes, and in some ways I can see Super-Ego as a possibility, except that they've been happily married for 27 years...But, maybe there just happens to be enough non-socionics factors in play to still make them compatible.
That said, I also think that my dad and my brother-in-law are likely the same type. But, I'm starting to think that my brother-in-law might actually be LIE.
I'm still pretty darn positive about ESI for my mom.
So, what might be some ways to tell whether my parents are Duals or Super-Egoes?
Or, how can I decide b/t LII or LIE for my dad?
