I realized that Ti people point out flaws left and right and get pleasure from it. If the flaw exists anyone has the right to correct it.
This I already knew though but... it made me realize this (and I hope ENTps and ESTps read the following carefully)...
Fi people look for power relation errors left and right, and get pleasure from it. If the flaw exists anyone has the right to correct it . So basically if you sin in a relational way and break trust, every fricking Fi person will either read your guilt, or see it and scorn the hell out of you. A pretty neat societal mechanism.
