I/E is obviously a thing. S/N has big correlations with g so it’s obviously tracking something. F/T is perhaps less obvious statistically(?) but introspectively and anecdotally-observationally still pretty clear, and P/J is the most questionable and confusing part of MBTI so I won’t defend it. Hypotheses and conceptual frameworks shouldn’t be pet causes.
Data: Wikipedia claims E/I is very correlated with E, S/N is very correlated with O, F/T fairly correlated with A, J/P fairly correlated with C and somewhat correlated with O, and Neuroticism isn’t measured in MBTI. So this backs up your claim that P/J doesn’t measure any concrete “thing”.
Clicking through the citation gives that N is not well-correlated with anything in men (a tiny bit with E/I), and somewhat correlated with the F/T in women. Also F/T has a small effect on extraversion in men, but it’s S/N and J/P which has the effect on women.
As far as I know S/N as measured by MBTI does not have big correlations with anything and it doesn’t even correlate with other scales designed to measure the same type of thing(intuitions etc.). Same for F/T.
