Our assessment was fairly accurate. But I agree with xzins that it's a little too inflexible.
I wonder how much of it is like fortune cookies - after seeing the fortune, you can find a way to make it apply to yourself.
To repeat, the Myers-Briggs can be useful.
The inventory itself says that the individual's perception of where they actually fit is more important than the box they get placed in by their answers to the questions.
There can also be float over time, so there's almost a retro-ductive zeroing in on where one fits in the "this era" of their lives.
I would predict float in Jude's result due to Law School. Put a bunch of folks in a touchy-feely seminary environment and they all start floating toward ENFP.
