Sorry, but I openly consider many long-standing theories of personality and intelligence to be mostly bunk by self-absorbed, neurotic and stuck-up psychologists, which is why being associated with Myers-Briggs type indicators and Carl Jung type theories don't carry any special "authority" in my book (Don't think I didn't see that on the site and consider it).
Always remember that these were all just people too, and when you read any of their books or ideas, always do so as though you were having a discussion with someone rather than simply taking them for granted as well-established and authoritative (as many of us have a great, unfortunate tendency to do these days). More importantly, do so as directly as possible, as other people's interpretations of other people's interpretations of someone's ideas are often so warped as to be almost useless, especially when the "awe" of the original source has been magnified to the point where simple heuristics and suggestive models become inflexible doctrine and dogma.
Also, it's pretty hard for a personality test that forces you to construct a clear-cut version of your own personality based on some select dichotomies to not match your own idea of yourself. But then whether or not it's accurate depends on how well you understand and know yourself to begin with, and a person who doesn't spend a lot of time deeply reflecting on their own experiences and understanding themselves will simply walk away with nothing more than a reinforced and over-simplified view of who they think they are... possibly to the point where the test results become self-fulfilling and actually influence future behavior to be more rigid and less adaptable.
Meanwhile the person who has daily considered their actions in depth and knows their own weaknesses as well as strengths would likely not need such a test to begin with, as they already possess a deeper understanding of where they stand. Furthermore, such a method of understanding encourages greater growth, as the means with which one can daily diagnose and fix those weaknesses they identify is always within their possession.
Also, within the context of comparing yourself to others, a personality test like this becomes completely compromised by the very intent to share the results instead of simply using them for self-discovery. It adds incentives that will keep you from being completely honest with yourself, thus your thread actually makes the test even less useful for anyone who participates than it might have been otherwise.
