A friend of mine did them in Norway...
Mr. Lars asked him if he found his own mother "sek-sually attractive"...
Apparently the tests are virtually copies if not literal copies of what the RNoAF uses for selection to their pilot training.
He (both psychologists) claim that the test will tell wether you are suited to be a pilot or not, "And they are very good at what they do"...
I am inclined to agree with previous posters that it is a great scheme to get money from the companies that use them.
