Reblogging for the comments I’ve seen others post. Ambiversion, although perhaps accepted widely in other personality systems and in general, is not applicable to MBTI. I am an INFJ; but I am definitely social. For a while, I doubted I was even my type for this reason. But the “I” does not mean I am 100% introverted, don’t like socialization, would always prefer to be alone, and to some degree, antisocial. MBTI is not based solely on the aspects of Introversion v. Extroversion, Sensing v. iNtuition, Feeling v. Thinking, and Judging v. Perceiving. This is why “quiz” or “test” websites can be inaccurate if only based upon these things. MBTI is based off of 8 cognitive functions: Ni, Ne, Se, Si, Fi, Fe, Ti, and Te. That is what makes up types like “ENFJ” and “INTJ”. There is no room for Ambiverted functions. These functions determine things like your social, mental, and emotional responses to things. Your function stack, along with your shadow functions, are particular to your type. For example, INFJ’s dom function is Ni. All of the dom functions are reliant on intro v. extro. This is a quite common misconception among people interested in MBTI.
Although, I wouldn’t compare this to the kind of SJW movement of MBTI. The way OP phrased it, it does sound SJW-ish, but that’s not the point. You just have to figure out what functions you use the most. There are most certainly online tests that test for function use, although all online tests are not 100% correct. Remember, you know yourself best!
