Can you fool a Lie Detector?

Answer 1

there is a possiblility if someone is trained to control the way their heart beats or their pulse rate. It is extremely difficult.There are "tricks"....ie: Taking sedatives to calm yourself down, putting a thumbtack in one of your shoes (under your big toe for example) and during the "Test" questions....you push your toe down on it....on one of the "LIES" they have you say...this INCREASES the recorded response.....they'll say "Gee..this guy really SHOWS when he lies...he tenses waaay up, when actually you did not, making a REAL lie easier to skate by on.

Look up books online, on the subject.....you CAN beat these machines...they are FAR from perfect...why do you think judges won't allow them into a courtroom???!

Good luck.

One trick that works is

You can also think of something really exiting when they ask your name the color of the wall and any obis questions like that and when they ask the questions you need to lie on it will show your heartbeat as normal.

Answer 2

Knowing the person administering a polygraph for pre-employment once, I asked to be given a second polygraph where I would purposely give false answers. I remained calm and didn't "figit" while giving lies to the questions, and PASSED, so I can say it is possible...at least in my case.

Answer 3

Lie detector's are commonly trusted devices, however, to fool one requires very little effort on your part.

You simply think of the most exciting thing you can, imagine yourself doing it; lie detectors need to take a 'base-reading' which allows the machine your normal skin conductance and heartbeat levels, the questions asked during a base reading are simple questions, like "What year is it? What is your name? What colour is that wall?"

If you think of a very exciting thing when those questions are being asked, you will fool the lie detector later, when the real questions start.

Answer 4

It's nearly impossible nowadays unless you are a true Sociopath. In it's infancy, polygraph tests were able to be fooled by people with good control of their breathing , heart rate etc, like a master in meditation. However , now the equipment has become so sensitive , with a skilled operator , they are in the range of 97% effective. Almost as accurate as DNA tests.

Answer 5

You may have to come up with a convincing lie quickly. Think of the lie as the truth. Make sure you do not say "um", "uh", "er", or anything else like that. Do not move too much, Do not shake your legs. Try not to sweat too much. Do not touch your face. Do not bite your lips. Do not stare at the questioner too long. Do not look right when talking. Do not lean away while talking.
