Because so far no one on these forums has actually produce reliable evidence to prove that any specific MBTI excells above and beyond in income.... there are a lot of crap research with bad sampling and the MOST APPAULING misreading of the data... there is a whole thread on cleaverness - which is simply full of misinterpretation.
In reality, at senior level in big firms it doens't seem to skew a huge amount from what I can see for a rep population.... slightly lower SJ, but not huge... But there is no evidence of that...
The most we manage to squeeze out the last set of data someone posted a link too, is that N types were likely to be more gifted, but it would need to be statistically proven.
So please, if you can find data to suggest that there will be a non representative spread of MBTI across different income band, which is reliable and doens't misreport the data, then we may have something to talk about, but until then I think it's plausable to think it's MBTI bull shit...
(I do think there will be a small skew in reality but not massive).
Ok 55% Normal pop of the UK is SJ (and I'm talking from memory so dont' quote me)....
At average income one would expect a similar proportion of SJ's
At senior levels ditto...55%.... there is nothing been produced to suggest MBTI skews income... nothing that has reliability/properly reported
