i think only for the ones identifying with the science too much hehe

if a psychologist/coach claims the mbti is useless compared to the big 5 they lost their way imo; and the same goes for the mbti-camp thinking big 5 is useless lol

either one should be taken with a grain of salt as basically all tests lack something in test properties

for an actual complete profile people should use multiple tests and for it to be useful the person taking it should have at least some trust in it (or in the person analyzing it)

ultimately, it's not the label but the power of introspection that matters
