One funny thing in MBTI is the tests often lead people to initially think it's about the four letters in a sense of polarity, when actually your type is formed not by binary ratios between letters but by the functional hierarchy in which those letters are elements of functions (ex. Introverted iNtuition, Extraverted Thinking) that are expressed in the same preferential order based on your type regardless of percentages. For example, the raw letters of an INFJ do not spell "extraverted feeling", but that is the INFJ's second most prevalent function.
Thus the only time percentages are relevant is if you're truly borderline with one or more letters, in which case if you review the potential types you'll likely find that one stands out as more 'you' than the other - for instance, an INFJ's functional hierarchy does not bear any resemblance to that of an INFP, likewise with INTJ / INTP. They are so very different in how their energy is expressed. When in doubt, pondering which of the functions (Extraverted Thinking, etc.) you identify with may be easier than trying to identify your type based on interpreting descriptions like "hard to impress, attracted to sad things," etc.
I see we already have a majority identifying as female. I'll not let myself rush to conclusions, let's just keep getting more IN-folk, well, in here
