Practice telling the lie over and over gain until it forms a kind of truth in your head and you don't even really remember what the truth is.

just relax and breathe normal ,think that the lie is the truth.dont stress and true to keep your heartrate down.

kame

they are known for being inaccurate , by simply keepin g your heart beat at a normal level you should decieve it well .

Houjo

A sedative could work. An upper will skew the results. Or lots of practise regulating your heart rate and breathing.

Tim

i think they just have to believe wat they say is true.. because wen, u do ur body wont react like ur lying

Jason

It only detects changes in levels of nevousness, etc... If he can convince himself that he's telling the truth the detector won't know otherwise.

The Lie Detector Test tests your stress level and heart rate. Keep calm and don't EVER hesitate.

They have to beleive the lie

Or not be worried about being caught in the lie

They will need to control thier body, heat beat, body temp

donielle

Valium or Xanax

Lie detectors rely on several things for accurate readings.
1.blood preasure
2.pulse
3.heartbeat & breathing

If you control your breathing you can control the others.Flexing the muscles in your legs from the very beginning of the test will help throw off the machine,but you have to do it all through the testing.
Pick a spot on the wall and concentrate.Relax after the beginning of the test.
Convince yourself prior to the test that a "lie" is true.(if your guilty)

Don't put your life in those situations...Don't lie...Well, not too much....HA HA HEE HEE...:}

They have to keep saying the lie until they believe it. Then when they take the exam just keep repeating the same lie they have practiced. The more they say it the more real it becomes and more convincingly they can repeat it.

There are also ways to biometrically fool the detector. By inducing panic throughout the test, especially on the baseline questions the results will come up inconclusive. (Puckering the anus or kegels will cause a jump in heart rate and make the machine look like you are nervous, but if done on the baseline questions no inferences can be drawn.) Many people, innocent or guilty, may feel nervous in a confrontational environment.

But you shouldn't lie. That is bad.

Panic during the original two calibrating questions. This means that any questions asked following these questions will be on the same level as the original calibrating questions. It is a hard skill that takes a long time to learn. I am experienced in this skill but unless you are in law enforcement I will not teach you so don't ask.

keep your heart rate down and breath normally oh an you must believe the lie is actually the truth the other ways are secret I could tell you but then the FBI and CIA would be after me an I'm not getting busted for some stranger who can't figure out how to beat the lie detector
