It happens all too often. I've been questioned too many times on this site if I accurately typed other people or if my view is even valid. And I rarely see it happen to intuitives. I've been studying MBTI for over a decade now, and I've been the same type since day one. I've read tons of books, articles, and keep up with videos on the topic. Not just that, but I'm an individual who has lived and experienced many different environments and people. And I'm not saying that I don't make mistakes on typing individuals. But I definitely see common patterns with specific types, and that is one huge point of why I choose to continue to study MBTI.As for putting a different type in your profile, while I've never actually done it, I do wonder how differently people would view my posts if I stuck INTJ (or unknown perhaps) under my name instead. I'd argue there's some practical use in assessing others' biases against you. One of the reasons I, personally, find typology interesting is because it highlights how people misinterpret your words and actions based on their own type or biases. It's too easy to misjudge people based on your own perceptions - and comparative data in that respect I think would be useful. For me, anyway.
