Pushing for 8 pages of this nonsense! =D
As for the few people questioning it... yes MBTI *IS* on very rare occasion used in businesses to profile their people.
And yes, of those cases, it is also rarely misused by someone who doesn't really understand it.
There have been cases where someone would be turned down from an application where they didn't meet the "desired personality", because their boss read somewheres in some magazine or newsletter that certain types are more difficult to work with than others.
There's dozens of different personality tests out there, MBTI's only a small sliver of it; enneagram, colours, and a few others are used. I had to actually take a colours evaluation for my college course last quarter... apparantly green = NT and orange = NP, and the E/I is a seperate scale.
In any case, there are businesses that do in fact profile people's personalities, but they're generally very rare, and of the few who do, not all of them will be misusing it; most just use it for teambuilding exercises so people can get along better, rather than forcing them to comply to some misunderstood standard.
