I think you have confused the MMPI with another test. The MMPI is not scored high or low. It is used to evaluate your mental health.
The best I can do to describe it is that they ask you about 500 questions which are variations of a much smaller bank of questions.
By asking the same questions in various ways they presume to be able to judge; truthfulness, paranoia and other personality traits.
It is meant to be followed up with a session with a psychologist or psychiatrist.
I have had to take it every 5 years for the last 35 years to maintain my security clearance.
It takes about a half a day to complete the test and interview.
But some of the questions are really off the wall. One of memorable one is ‘Do you ever have black tarry stool?’. Of course there is the ‘Do you hate your mother’
I recall it did take a very long time, and it did ask the same questions using different verbiage. (As if you couldn’t figure that out, right?)
Anyhow, I do know that I was turned down for one position because I wasn’t “like” the other employees and wouldn’t fit in to their “atmosphere”. I translated that to, “You’re not a robot, and never will be a robot. We don’t want you.” LOL!
Whatever test it was, it was interesting.
Yes, I have black tarry stool every time I eat black tar.
IQ tests don’t mean anything. As a kid, I was the guinea pig for grad students learning to give IQ tests. After a while, you learn the various tests and how to manipulate them. Sometimes I’d have fun pointing out flaws and mistakes (no, you gave me the right handed maze when you should have given me the left handed maze) and they’d stutter and stumble over what to do. The first test I took, the WISC, was at about age 6 and pointed out the wooden car didn’t have headlights and the PhD was flabbergasted and told everyone about it for years. How silly.
By about 12, I was getting bored with it all so would intentionally miss the required number of questions to end the test. The last question of the last test I ever had to suffer through was how many buckets of water to fill the container. Who cares? Simple solution would be to drag the hose over to fill it.
