I don't know many of us who would get "away" with this question. Technically taking an pen or pencil from the office is stealing. So in my mind I would have to answer yes to that question. I don't really know how the "lie detector" works. If it doesn't bother me that I took a pencil from work) would it show up as a lie if I answered yes to the question?

Lie detectors work on the assumption that an untruth causes autonomic responses in your body, like elevated heart rate, perspiration, deeper or heavier or faster breathing, and blood pressure. If a lie doesn't make those things happen a lie detector is more apt to register a "truth" or a null. Lie detector tests rely on the assumption that someone will feel guilty enough for his/her body to betray them regardless of the answer.

You hear about lie detectors all the time in police investigations, and sometimes a person applying for a job will have to undergo a polygraph test (for example, certain government jobs with the FBI or CIA require polygraph tests). The goal of a lie detector is to see if the person is telling the truth or lying when answering certain questions. When a person takes a polygraph test, four to six sensors are attached to him. A polygraph is a machine in which the multiple ("poly") signals from the sensors are recorded on a single strip of moving paper ("graph"). The sensors usually record:
  • The person's breathing rate
  • The person's pulse
  • The person's blood pressure
  • The person's perspiration
Sometimes a polygraph will also record things like arm and leg movement. When the polygraph test starts, the questioner asks three or four simple questions to establish the norms for the person's signals. Then the real questions being tested by the polygraph are asked. Throughout questioning, all of the person's signals are recorded on the moving paper.
Both during and after the test, a polygraph examiner can look at the graphs and can see whether the vital signs changed significantly on any of the questions. In general, a significant change (such as a faster heart rate, higher blood pressure, increased perspiration) indicates that the person is lying.
When a well-trained examiner uses a polygraph, he or she can detect lying with high accuracy. However, because the examiner's interpretation is subjective and because different people react differently to lying, a polygraph test is not perfect and can be fooled.



They are not accepted as legal evidence in almost any court as far as I understand it because they have never yet been proven to be an exact science. They are subjective based on the testers experience and interpretation of the bodily responses as recorded on the graph.

They are good at finding lies, but they suck at finding true. Sociopaths who have no problem lying display none of the signs of stress in lying that truthful people do. In college I took a bottle of booze from the liquor store I worked at, and later passed a standard test given to all employees every six months to see if we were stealing skimming, etc.

I was promised overtime if I came in one weekend when they were desperate. Broke a date to do it, but was told I'd get double time. My check came, no time and a half or double time. Boss said "I changed my mind about that"

So I figured out the hours - subtracted taxes and lifted the exact value bottle (rum?bourbon?). When they asked me if I'd ever stolen anything, I said "No", but then, I did not think I had, as by all moral rights I was entitled to it. Plus, the sorority girl I stood up would not go out again.:(

She had great.... hands:(:(

the interesting part for me is listening to the audience. listening to them boo when the chick tried to protect the girl from a difficult question. listening to them cheer when she decided to continue on with the game. listening them ooooooo when a difficult question was asked. that audience didn't purchase their tickets to see people tell the truth. they came to watch someone destroy their marriage. to rip apart their family. they came to revel in the destruction of a human being and they didn't much care for who or how.

i come away from this thinking this must be similar to roman's chanting for death in the arena. it makes me wonder how far that audience was from cheering for a lion to eat a young woman. or an old man. or a child.

It's perverse. At the very least, at least it consists of willing contestants who openly subject themselves to this ridicule. Nobody is forced to go on the show.

As these ridiculous reality shows get worse, I'm reminded more and more of the 1982 Stephen King novel The Running Man, later made into a movie starring Ahnold. It's seeming more and more likely that something like that will come to fruition. :(

Or maybe you're a sociopath.

It's really not the subjectivity or lack of exactitude in court that's the problem. There's a battle of "expert" interpretations of the same "facts" in many cases. The problem with the admissibility of polygraphs in court is the perception of infallibility and the chance/certainty, therefore, of prejudice in court. They're kept out for the same general reason that extremely bloody crime scene photos are often excluded. We want jurys to weigh evidence and decide, but not be inappropriately swayed one way or the other (unless it's my way, of course).

very true. however, many gladiators were free men who entered the arena for money. so imo the comparison still holds. besides, in any society there will always be persons willing to risk death itself for a small cash payout. that doesn't remove blame from those who would seek to exploit such persons for financial gain. though it does mean i don't feel 1 bit sorry for any of the above.

I think it was on msn's site or cnn, they have a video clip where they wer discussing the show. The host was acting all holier than thou, commenting on how horrible it was that is was being shown on tv and how they were ruining peoples lives,,,,blah blah blah. So one of the people on the panel made some comment about well isn't that what you all do when you exploit these clebrities and report on all their secrets and stuff. The host just ignored the question and moved on, relizing he couldn't say much.
