The second nail was the completely intra-personalized descriptions present on all of the sites I could find about the subject. All of them are marginally different from another, and none of them correlated between each other in the slightest. I found on one site I fitted best as an IEE, on another, an SLI, On another, a IEI. What? How does that make sense? I originally assumed it was a problem with me not being able to nail down certain aspects of my personality and behavior to paper, but as I read more and more sites concerning the subject it quickly became evident that it was not me who was the problem - it was the rampant bias this theory facilitates with it's highly personal characterizations written by individuals who likely have different views on what the separate personality traits represent.
The third nail was intuition. It came babbling along after the first two and promptly reminded me that you really cannot assign 16 types of personalty/reality interaction to every human being on this world properly without being discrepancies. Human interaction is too complex to be described by a mere 16 types, and even then, it's probably impossible to type a person to anything at all.
For me, this theory makes no sense. Infact, it's a load of garbage. I can't fathom why none of you here have looked into this more deeply and seen it. I wager a few people reading this post will even try and use the theory to affirm my behavior to one of the types. Quite frankly, I won't be surprised. This theory is the perfect escape for a person who can't approach the world and interact with it properly, by their own means. It acts as a dead-end stepping stone in a pool of acid. You'll jump on to it, float for a while, and realize as you get older just how far you've drifted away.
