It probably has something to do with the fact that "these people" are worried that failing a test filled with completely arbitrary and asenine questions might cost them the chance to obtain their dream job. I realize that this test has been in use for many years and does create a somewhat accurate personality profile, but obviously it's not the 'be all end all' component, or they wouldn't be giving the people who failed an opportunity to clarify any problems flagged by the test. (On the FAA's dime, no less.) At any rate, I'm quite certain that anyone who failed the aforementioned test for any reason has every right to be concerned about it without having you ridicule them. I'm surprised that your arrogant post hasn't gotten you flamed yet; you certainly deserve to be, you dolt.
I don't see how I would be considered a dolt, and the post was not arrogant. Folks here are complaining about a standardized test that accurately profiles an individual based on measured responses to scientifically-formulated questions. The test is designed to measure your accurate responses to questions by asking them in different ways. If the test were to ask if you have ever smoked marijuana, and you say, "No", and then it later asks if you have ever taken recreational drugs, and you say. "Yes," then it knows you are lying. While its main intent was to diagnose mental issues, the MMPI also functions to determine the test taker's individual personality structure.
"Failing" the MMPI means that the answers to some of your questions were outside the boundaries set by the test. As we have read on here already, there are people who have answered the question of, "Have you ever lied?" by responding, "No." THAT IS WHAT THIS TEST IS DESIGNED TO DO. In much the same way as the Myers-Briggs test, the MMPI can detect people trying to game the system, even if the people did not do so intentionally. That is why they are being told to retake the test - if the new test results line up correctly, then there should be no problems. If, however, the answers line up outside the boundaries again, then either the person is not qualified for this position or he/she is trying to answer them non-emotionally. Your first answer is always the right answer on these tests. There is no "right way" to answer a question, because attempting to do so will trip you up in a later question. The questions are neither arbitrary nor asinine, but rather qualifiers.
Short of having psychologists on the payroll to test each individual in an interview setting, this is the cheapest and most accurate method of initially weeding out those that are not cut out for the position.
This is from someone who is married to a girl going in to a clinical psych program, who, oddly enough, just got through talking about the MMPI in class.

Now watch me (hopefully) get a PEPC invite and fail the MMPI. Then I'll be right back here with the rest of you.
