Well theres a truth about socionics and MBTI, though its more like whats not true. Its a truth that some people fail to grasp. Socionics and MBTI is a system of thought, an isolation. It is something that is based completely on assumptive logic. God did not come down from the heavens and present this system to us. There is no divine law in this. Socionics and MBTI are completely idealistic systems. Most people out there in the MBTI and Socionics community are searching for an answer or something in this. They think they will find their type, their absolute prophecy. They think there is a type that is made just for them, and they are supposed to fit in it perfectly. There is sort of a psychological attachment to the concept of actually finding something that completely understands us, some type of perfect system that defines everything that we are. Perfection is not something that we will ever reach. This isn't saying that perfection isn't something that we should try to reach, because I believe that we should. Its just everyone seems to be placing their trust in something that never will work to absolution instead of actually placing trust in their own uniqueness. People should express whats inside themselves, not what some categorizational system tells you you are.
The truth is, a person probably fits into multiple different types. Hell, a real person probably fits into something that types do not represent. Yet, people have turned a theoretical system into something that stereotypes people. Some of you think that they understand other people before they even open their mouths. Its a epic failure. Instead of using socionics as a tool, socionics is using us as tools.
