All models are wrong, but some are useful.

I have found the MBTI to be useful despite the empirical inaccuracy of the test itself. Even without taking the test, people can self-identify as one (or more) types. This then serves as a meaningful basis for discussion as well as raising awareness that people are deeply different in terms of their ways of thinking. It is quite an eye opener the first time you see someone self-identify as a personality type that is very different to your own.

None of the personality theories are 'proven' of course. We won't get that until we have a fuller understanding of the brain. But it is well accepted within psychology that personality is a thing. And personality types (Big 5, MBTI, etc) are useful models for now despite their shortcomings.

This is a fairly good post with some additional thoughts on the MBTI debate: https://dynomight.net/in-defense-of-myers-briggs.html

Check out “the human element” which is the basis for firo-b.

It actually has international data to support its model.
