Here's the message psychology/psychiatry/most world religions feed you: you're broken, you have problems, you have this disorder, that disorder, etc.... Either way, the message is that something's wrong with you and you need to turn yourself into what society deems as "correct."
Here's the message Socionics feeds you: you have a mind and your mind came in a type. Your mind was not a mistake. You just need to figure out how to use it.
