Yeah, I think the HSP thing is actually pretty useful but unfortunately it is marketed as sort of superficial "self-help" stuff so people who are into it get all fluffy and annoying about it. One the one hand I don't blame people for not taking it seriously, but on the other hand, if you actually read into it and the research behind it, it's not crazy. (People like to have opinions about things they haven't actually read.) At least on the sensory level, it does seem to be that some people easily get deeply overstimulated and others do not. Scientifically speaking, it's no secret that some people have problems with "sensory integration", especially people on the autism spectrum, but not always those folks. I'm not on the autism spectrum but I have a very hard time with some sensory stuff (loud noises, crowds, too much "going on" at once) and I do believe it is directly connected to PTSD. There has been research done on that, too. And, as in the video, there are people who experience the sensory effects of other people's emotions, and this seems to be a real thing. It's not a superpower, it comes out of PTSD (I believe) and again, this is fairly evidence-based. (In any case, people who are really into the MBTI should have a little more self-awareness...the MBTI is not exactly taken seriously by the scientific community, to say the least...it has not been studied seriously and with reliable research models the way, say the Big Five has been...it simply hasn't...most serious academics find the MBTI and Enneagram no just hokey but actually new agey psuedo-science! I mean, you can find some academics talking about it here and there, but you can find that with most fringe/new age psych theories including indigo children!)
I assumed INFJ for her type too but I need to learn a little more about MBTI...
