That is why there are "other" typology descriptions out there ... most type descriptions are written the way that you described, all written by some ENTp or INTj in some dark office somewhere with indirect data and maybe a few personal experiences. *points at self*

That is also the reason why there is so much relationship type bias prevalent in those descriptions, do you really want another set of type descriptions "exactly" like those type descriptions?

But if that is your cup of tea, fine and dandy ... no one said anyone had to contribute if they do not want to contribute.
