I briefly flagged the preceding comment for "psycho-bullshit" before concluding that it was just a really forceful way to say the developer personas were pseudoscientific (of course they are, nobody is claiming otherwise) but I think it's worth calling out that MBTI is also pseudoscientific; it has no real validity, or even test-test reliability.
I would guess that lack of repeatability happens a lot with any self-reporting scheme, but I am sorry that I accidentally picked such a polarizing "people generalization" scheme to use as contrast. Maybe I should have used "introvert versus extrovert" or something
Anyway, their sibling comment told me what I wanted to know, so in that way I'm wasting more of my time contributing to this
