While I agree those ladies were a bunch of loonies, I don't think the test is supposed to be predictive (this is how you will be), rather descriptive (this is how you are).

Although I've had this same argument with people over the function of dictionaries being descriptive (this is how words are used) rather than prescriptive (this is how you should use words).

I got "The Mediator" or something and my boss got mad at me for being an "arty farty hippie". Apparently the correct answer was to be "The Analyst" like my coworkers

I worked for one of those companies that paid like 15k per employee to spend like half a day figuring out which of 5 types you are. Somehow I got all 5 and confused quite a few people.

Pretty judgemental for a P.

Depends on moods, and also, many people have issues at making the difference between what someone is and what they'd like to be. Like many people want to be helpful, but not many are helpful outside their own social circle. (Which is fine, but not the same as being helpful towards everyone.)
