^ True, although, as RB pointed out, the test isn't really useful for people who are already very familiar with the cognitive functions. I am pretty certain by now of my own type, for example, and therefore do not see a point in taking the test as the questions contain statements that very clearly hint towards a certain function. For a rookie, this lingo may not be so obvious.
I think the problem with many MBTI tests is precisely that there are too many questions that are worded badly, and more importantly, as RB said, these present false dichotomies that forces one to make choices, which in an accumulative fashion, can result in inaccurate typing.
With certain preferences come certain other tendencies which, I guess is why the authors have decided to lump them together in paragraphs, rather than split them and thereby cause more confusion.
However, I can see your point that it would be nice to have more options to choose from as the test does feel as if it is attempting to confine one into a category quickly.
Also, if you consider yourself an XNTp type already, and you are left with these two options, I think the test has done a pretty good job compared to other tests that may leave you with anything from INTJ to INFP, to INFJ.....etc
