I was first introduced to the Myers-Briggs test about 15 years ago when I was helping an MBA student analyse a teacher in the movie "Stand by me"....About an inner city teacher in the US who had to deal with unruly students.
She had to explain what she thought his personality type was.
She got/I got a 95 on the assignment....Never got that mark again for the remaining assignments..Bit of a fluke...But yeah, interesting...Someone told me HR departments for some companies use the results of the test when team-building.
