Took a test once, never again
Process is like this, at least for a 24 hour retail shop:
1. Run through the list of Yes/No questions, first few are innocuous to get a baseline, no recording.
2. When they ask something like, "Did you ever steal anything?", you admit your transgressions, notes taken.
3. Repeat step 2 until you forget. Feelings of shame and embarrassment (unless you enjoy being a thief).
4. Hook up skin galvanometer, pulse monitor, and one more sensor which I have forgotten.
5. Repeat the question list.
6. When they reach the embarrassing question, they ask, "Besides A and B, have your ever stolen anything?"
7. You think of something else, go back to #6, until you get pissed off, and say "No" even though you did.
8. Feel the sweat squirt into your palms, hear the needles swish, (this was in 1974, mind you), and know you fail the test. Resist punching out the examiner and leave.
The test penalizes people who have good memories and who have consciences. Psychopaths should pass easily, as will Alzheimer patients.
I once advised a young woman who was applying to the FBI. At about step 7 she realized that padding an expense account, although advised by her supervisor to do this, was actually wrong. Good Catholic girl tried to bluff her way past, failed. She later became a successful MD.
Now I've read the CIA doesn't care about your sins, they just want you to confess all and show you trust them with your soul. They can always use a good thief.
