There is a reason I didn't select any personality types for my profile. As I was perusing this lovely site, I've noted that there are many people who are quick to look for what type someone classifies as, and immediately feel that they already know the true extent of that character, and can instantly place a stereotype upon the person one tends to be. A personality type test merely places a generality that overall covers the basics; an IMHC reading or MPH4573.6 cannot define the essence that constitutes my being or my mind. A characteristic may be generalized in description; but the quality possessed by an individual molds to a form that fits only the shape of that person, for its purpose and origins could never be replicated to the exact structure within another, no matter how seemingly similar they may appear. We all come from different cultures, backgrounds, environments, people, places, experiences, mindsets, etc; so it is impossible to place me in a category that may only apply to the generalities I do consist of, but not the details. The details vary greatly, and may even shape the generalities completely different than what they at first appeared to be. I am my own person, as we are all, and we should let that alone define us. A reading will not define me.  
However, I am not closed-off to the idea of reading into the types of descriptions they do have. I find it quite interesting. I would use it as a guide to help me grow and develop by helping me recognize my blind-spots and faults, but definitely not to permanently categorize myself.
