my friends husband has already failed 2 tests. the guy gets super nervous. any suggestions. this is for police enforcement.
"Just remember my friend, if you believe it, it's not a lie" Just goes to show how fallable those machines are. No one should ever submit to a lie detector test if their life or liberty are on the line. It's all mumbo jumbo and subject to the tester's "interpretation".
I've heard to put a thumb tack in your shoe and step on it each time a question is asked. That way you get the same response every time.
I think its that you step on the tack when you answer truthfully to the questions at the start that they use to get a baseline for the important questions later.
I'm not sure that nerves have much do with it. But then again, neither does telling a lie or telling the truth. I can say that from experience, having failed a polygraph test several times. A polygraph test isn't a lie detector, it is an interrogation tool. It measures physiological responses, but those responses are only loosely associated with honesty. The results are open to interpretation. A polygraph test result is only as good as the interrogator. Polygraph testing is ******** and the polygraph operators know it. It isn't about passing the test. It isn't about telling the truth. It is about convincing the polygraph operator through the machine. The two questions that always hung me up were over my drug history (which I was honest about) and whether or not I was a terrorist or acting as an agent of a foreign nation. Looking back, it wasn't worth the ******* stress. Now, to me, no job is worth taking a polygraph for. I will never take one again. It is likely that the interrogator doesn't believe your friend is lying. It could be that the interrogator just can't put a stamp of approval on your friend until his physiological responses are within ranges that they can accept. In that case, he can keep plugging away. If he can request a new interrogator, that may help.
"Why are you nervous, George?" "I get nervous when I talk to policemen." "Of course you do, George. You know who doesn't? Thieves."
I would never trust law enforcement to administer a fair test. They're looking for the guilty person, so their results would be skewed that direction.
I don't know. Maybe I could beat the machine (the lie detector). Uh! Who do you think you are? Costanza?
I heard if you hold your breath, you can pass. Investigator: Butthead, have you ever stolen any money from Burger World? Butthead: No. (Light goes green) DING! DING! DING! Butthead takes in the deepest breath he can.
I've done a little research on this in the past as there as several articles on the internet that tell how to beat a lie detector test. The key is "fooling" the operator of the test when he is asking the "baseline" questions....i.e. questions that are easy to respond to like....Are you 30 years old? Do you live on Oak Street, etc. etc. Supposedly while he is asking these these questions you can do little simple things like 1) Curling your toes or 2) constrict your anal sphincter (not kidding) Both will result in throwing off your blood pressure just slightly enough to give you a false reading on your baseline comparison score. Personally, I would never volunteer to take a polygraph. After all, if they were 100% correct, then courts would allow them as evidence.
It's all about heart rate and blood pressure. Anything that can mess up their "standard questions" at the beginning will give them inconclusive data, so they can't assume you are lying. I was told to get blasted on caffiene before the test, to the point where you almost shaking. Everytime you answer a question, the machine will read spikes. I guess if they ask you to lie about something as a gauge, this wouldn't work as well as the "stepping on a tack"/anal sphincter methods.
Some courts have abolished the complete bar against admission of polygraph exams and now use the standard expert witness test. The key is the person administering the test.
It may be somewhat about blood pressure, but I know some lie detectors tests that place two electrodes a couple of cm apart. Then you ask a question and the resistance between the two points will change ever so slightly due to sweat.
